Bellow Sealed & Piston Valve with Diapharagm & Electric Actuator

CAT# 11 / QTY: 500 PAGES: 20 (4+16) CLR : Special Blue / BLACK

Bellow Sealed & Piston Valve

Introduction - Bellow Sealed ValveIndexBellow Sealed Valves are a new breed of Industrial process valves,

designed to eliminate Valve leakage and also known as 'Zero Leak

Valves' or 'Emission Free Valves.'

In these valves, conventional gland packing is supplemented by a

metallic Bellow Cartridge joined to the valve bonnet at one end, and the

stem at the other end. A bellow is a long accordion-like tube. As the

valve stem strokes, the bellow expands or compresses with the stroke

movement. There are no sliding or rotating seals through which process

fluid can pass.

Thus the fluid will enter the valve from the seat of the valve & come in

contact with the bellow, but will not come in contact with the stem. Since

the stem is the only moving part in the valve, it is a source of potential

leakage through the gland due to constant friction caused by the axial

movement.

In a bellow sealed valve this potential leak is totally avoided due to the

metallic bellow which blocks the leak path effectively by not allowing the

media to come in contact with the stem and thus the gland.

A bellow is the heart of this type of valve. There are two types of bellows:

formed and welded leaf.

Dangerous fluids are a permanent menace to man and environment.

Leakages need to be avoided during operation. The ever-increasing

concern for environmental issues has led to use of both leakage and

maintenance free bellows sealed valves.

Bellows sealed valves guarantee Zero leakage to atmosphere and

therefore is an efficient and economic contributor towards security of our

surroundings.

Reliable durability because bellows are produced from a single piece of metal. Guaranteed 10,000 cycles or more life cycle

Because of wide opening between plies of bellows,bellow compression function will not be impaired bybits of foreign matter in fluid.

Easy to test for quality, bellow can be produced with uniform quality.

Quality control

Formed BellowsType Welded Bellows

Of doubtful reliability because of a number of welded joints. Plies can be affected by Heat, and thus cycle life is hard to predict.

Wedge-shaped openingbetween plies will trap foreign matter in fluid, leading to bellow failure.

Very difficult to inspectwelded spots for quality,hence quality difficult to control.

Bellows seal valves are Zero emission and maintenance free. An uninterrupted

metallic barrier is positioned between the piping and the environment. The

components that during valve operation are subject to relative movements are welded

onto the extremities of a metallic bellows that absorbs and compensates the shiftings.

Hence these valves are suitable for any fluid and are recommended when Zero

emission characteristics are required to protect the environment and the health of the

workers from pollutive leaks, to prevent expensive wastes due to loss of energy and

fluid, and to eliminate the not negligible cost of replacement of the packing. In

conclusion, the valves are particularly suitable for dangerous, inflammable, lethal and

explosive media.

The particular characteristics of these valves have been obtained by means of correct

sizing and material selection, by a shrewd and long test in laboratory and plants

under severe working conditions allowed by the rating, and a quality system. The

adopted bellows are fully in compliance and are made of Austenitic stainless steel or

Hastelloy. The life (corresponding to the number of cycles) is much longer than that

required by the relative standards. Generally bellows Seal Valves are fitted with rising

not rotating stem to avoid additional torsional stresses on the bellows.

?Valve body in cast or forged construction to suit your requirements.

?Spindle with bellow assembly easily replaceable-easy of maintenance.

?Gland packing available as standard in addition to bellow – to arrest any gland leakage in the event of bellow damage.

?Wide choice of bellow materials – including inconnel, Hastalloy, Monel, etc.

?External pressurization of bellow – leading to longer bellow life.

?Welding of bellow done under most stringent conditions.

lBellows selected for higher stroke length than necessary – ensures longer life of bellows.

lTemperature compensation considered as standard during sizing and selection of bellows.

Formed bellows – which is made with the help of rolling a flat metal sheet into a tube with longitudinal fusion welding, in

short the tube is hydraulically formed into bellows with rounded and widely faced folds.

Welded Leaf type bellows – It is a washer like plate of thin metal which are welded together. The common difference

between Formed bellows and Welded leaf type bellows are as follows.

There are two types of bellows:

Advantages

Inclined Design In Forged Construction

Encapsulated Design

3 Piece Design

The more commonly used bellows is a Formed type instead of welded because of its advantages.

For better flow characteristics.

Are bellows seal globe valves can be provided with encapsulated bellows, which are protected from particles,

velocity of following media, and bellow erosion etc. thus ensuring long life of bellow.

These 3 pieces design accommodate any length of bellow with no change in body/bonnet pattern.

Valves with bellows designed for higher cycles are available on request.

Special design can be used for chlorine application

It has been proven through various studies about process plant emissions that 75% of leakages cause:

1) Environment pollution.

2) Production loss

3) Process problems and

4) Energy loss.

Bellow Seal Valves are highly recommended for Thermion - 66, down herm vapor, hot oil, HTM, Vacuum, Steam,

Ammonia, Refrigerant, Phosgene, Chlorine, Hydrogen, Oxygen, CO, Hazardous and Poisonous Liquids / Gases,

Radioactive substances etc.

Why Bellow Seal Valve?

ORDINARY VALVE

(Observe leakage through gland)

BELLOW SEALED VALVE

(Gland Shut-Off With Metalic Bellows)Fig. 1



CONVENTIONAL VALVES

Gland packing

None

Very common. Due to the design conditions, gland leakage occurs with in a few cycles, no matter which make valve or what quality of gland packing

Needs to be replaced very often

High

Considerable amount through gland leakages. Normally large amount when leakage remains unattended.

Very high for replacing gland packing

Very High .Gland packing needs to be replaced /repacked often. This cost along with equipment down time, man hours spent etc. very high.

Very Low -in Months. Due to Leakage through gland, certain parts erode, making the valve irreparable after some months, Valves needs to be replaced

Highly unsafe especially when the media is hazardous and poisonous.

Initially low but very high after some years if cost of packing, downtime, man-hours spent, number of valves replaced etc are taken into account.

PISTON VALVES

Piston ring

None

Occurs as soon as the rings (which are made of gasket material) wear out.

Rings need to be Changed frequently

Very high

Large in case of leaks

Very High for replacing rings

High as rings need to be changed atleast once in six months

Low.

Can be used only for limited media like low pressure steam, hot water etc.

SUDESUDERating to DIN 2401



The Piston valve is seat less and glandless valve. At the

heart of the piston valve are piston and sealing rings. A

burnished piston seals against metal reinforced graphite

rings to achieve leak proof shutoff. This unique design

ensures long life even at temperature up to 800°F (427°C).

Seal tightness in a piston valve is obtained by a cylindrically

shaped plug, connected to a spindle, and operated by the

actuating force, which enables it to move through thinner

diameter of two packing rings. When the piston is in the high

piston, that is, held by only the upper valve ring, (which also

ensures tightness to the atmosphere), the valve is open.

When the piston is lowered and is held in place by both the

upper and lower valve rings (and thus ensuring seat

tightness between the valve inlet and outlet), the valve is

closed. Because of the use of packing rings, which have

alternate layers of graphite and stainless steel, the piston

valve is considered a “soft-seated valve”.

The contact between the piston and rings(sealing effect) is

positively assured by means of the pressure exerted by

stud bolts with depending on valve materials, Belleville

washera are fitted to compensate expansion due to

temperature variations.

A typical feature of the piston valves- compared with globe

valves-is that the piston is always held by at least one

sealing ring. Therefore, there is no vibration during closing

and opening operations.

Another primary feature of the piston valve is that the two

cylindrical seating surfaces, the bottom valve ring and the

piston come in contact when the fluid flow is already nearly

cut off. Another unique properly of the piston valve is that

with the valve completely open and the piston completely

supported in the inner diameter of the upper valve ring, it is

protected against erosive/corrosive elements as well as

prevented from having foreign matter deposited upon it.

Piston-valves –contrary to globe valves –are bi-directional.

That is, they can be installed in a process line in both

directions of flow. However, the most common installation is

with the fluid inlet pressure below the valve piston.

Since no metallic sealing surfaces are present, therefore is

perfect interchangeability of all components. A new set of

spares can be immediately fitted without the need of

adaptation to other existing parts. Therefore, inline

reparability and maintenance is easy, does not require

specialized, and will always make the valve like new.

First application, still widely used, was the tight shut-off of

low and medium pressure stem.

Piston valves have been selected to meet the server

demands of a large number of requirements in fluid

handling applications in the industrial sector. As such, they

are used in process lines containing many different fluids

such as steam, superheated water, thermal transfer fluids,

ammonia, LPG, hydrocarbons, acids, alkaloids, etc. their

ability to provide perfect seat shut off and packing tightness

and their along term troubles-free operation, ensured by

reinforced seal rings, have served to greatly expand the

number and types of applications.

Although the seat rings are suitable for use in temperatures

in excess of 1022°F (550°C), their use is limited to the

restrictions applicable to the body material, as well as that of

other metallic pressure retaining valve components. It

should be noted that carbon steel bodies can not be used in

temperatures above 800°F (427°C)

The piston valve which has achieved world-wide

recognition mainly due to tight sealing against high

temperature and pressure.

SUDESUDEParts of Piston Valve

The sealing system is astonishingly simple and

extraordinarily effective; always leak-tight across the

ports and to atmosphere.

The shut-off assembly comprises of a stainless steel piston,

two resilient valve rings and a ferrous-metal lantern bush.

The sealing surface consists of the cylindrical surface of the

piston and the corresponding inner surface area of the

sealing rings. This provides a very large sealing surface

compared with globe-one of the reasons for the piston

valves excellent seal.

The upper valve ring is of special material provides a reliable

seal to atmosphere. The middle layer of the ring is of special

(PTFE) and is fully contained between laminates, the valve

body and the piston, in both the open and shut positions.

The pressure on the valve ring is provided by the nuts

securing the bonnet to the valve body. Belleville washers are

fitted under the bonnet nuts to ensure that the pressure of

the bonnet on the valve ring kept constant. This maintains

uniform contact of the PTFE with the bush, to the lower valve

ring, which is contained in the body. The resilient sealing

rings are thereby compressed and transform this thrust into

a radial acting pressure. Being supported against the wall of

the valve body, the laminates of the valve rings are

compressed around the piston and thereby produce an

outstanding seal.

Piston valves are fitted with Belleville washers as standard-

in conjunction with the resilient sealing rings. This produces

a spring-action selling system. Owing to the different co-

Maintenance-free

Compensation for thermal expansions

efficient of thermal expansion of the various valves

components, fluctuations of pressure and temperature

create thermal expansions which inevitably lead to

leakage. The Belleville washers however maintain constant

pressure on the resilient valve rings and automatically

compensate for any thermal expansions that may occur.

The piston valves stay tight without maintenance.

Foreign matter in the medium cannot harm a piston valve.

When the valve is being shut and the piston enters the lower

ring, it automatically sweeps out any particles of sand,

welding globules or other impurities present in the medium.

The possibility of damage to the sealing system through

abrasive matter suspended in the medium-a well-known

problem with conventional globe valves-is-effectively

eliminated with piston valves. Fibrous and contaminated

media can be reliably shut off without trouble.

Piston and the body: permeability to gases is reduced to a

minimum and a optimum seal to atmosphere is guaranteed.

The lower valve ring provides the seal across the ports. The

lantern bush serves as a distance piece between the two

rings.

The thrust produced by tightening the bonnet nuts acts

axially from above, this thrust is transmitted from the upper

valve ring via the lantern.

Comparison of Bellow Seated Valve & Piston Valve

Bellow sealed valve have formed/welded bellows

instead of glands. Bellow puncture over a period of

usage-very much like the bellows in mechanical seals.

The piston valve is a glandless valve. A burnished

piston seals against metal reinforced graphite rings

Acceptable energy saving

Piston valve –user industries

The outstandingly good seal offers two advantages which

should not be over looked; there is no loss of medium (cost

factor); and toxic or aggressive media cannot endanger the

environment since they remain in the piping system. Piston

valves are leak tight-both across the ports and to

atmosphere.
