Direct action regulation valve

Type RVD

RVD is a direct action pressure regulator. It isdesigned for controlling steam, oil, air and water

. We produce it with the screw connectionsof R1 / 2 " up to R6 / 4" and for nominal pressures ofPN 16 to PN 25

All internal valve parts are made of stainless steel(1.4301). Membranes are a combination of stainlesssteel and Teflon. Housing made of cast iron, ductileiron or cast steel.All direct action valves regulated pressure o deviates

from the set pressure. Deviation is depending on thecurrent flow. Valves with direct action also have asmaller opening force so there are produced only forthe smaller sizes (DN). If it is needed a bigger DN, itis recommend to use pilot operated valve, likeRVSU type valve witch have servo device. ValveRVD has the lowest price so you should always beapplied when technological requirements allow it.

RVD type can be mounted in any position. Also itallows the adjust of the regulated pressure without a

system stop. On flow rise, regulated pressure tends todrop. The maximum deviation from the presetpressure is up to 10% of regulated pressure.

RVD valve is designed to control pressure exceeding2.5 bar. For pressure regulation below 2.5 bar, it canbe used modified version of RVD valve labeled asRVD - N.

RVD valves are used for pressure ratio (at the inletand outlet) four to one (p1 / p2

Regulation valve

Type RVSU

Regulation valve type RVSU is a mechanical servopressure regulator. This valve is designed to control

steam pressure or air. It consists of two parts, themain valve and pilot valves. The pilot valve, uses themembrane located at the bottom of the valve controlsthe main valve, so this system is called - servo valve.Steam pressure regulation with the valve typeRVSU is very precise. Practically, the steam pressurebehind the valve does not depend on the current flowof steam or pressure applied to the flow of 0 to 100%of maximum flow. The advantage of servo regulationis virtually unlimited ratio of input and outputpressure.

All inside parts of valves are made of stainless steel,membranes are a combination of stainless steel andteflon(PTFE), and the casing is made of cast iron orsteel.Capacity depends on the valve inlet pressure and theregulated pressure. For the calculation of capacityuse is Kv values obtained by measuring the valve.These coefficients are given in table below-right.These coefficients are given in table below, andbelow the table are given the equation for flowcalculation.Valve type RVSU found is widely

applied in many industries. It has a long work lifetime, low cost and relatively simple maintenanceprocedures.

Water supply program

Type RP10 - 1

PV

S1

S2PS

The picture (right) is shown the basic version of apressure regulator type RP10 - 1 On the basis of thisversion was developed full range of control valvesfor water.

The main valve is controlled by a pilot valve (PV).Through ball valve S1 and choke valve PS waterflows to above side of the main valves memebrane-diaphragm. If the pilot valve is closed then thediaphragm will push the plug unit-disc of the mainvalve in the closed position. If the pilot valve is fully

open, then the liquid from the space above themembrane will flow out in the pipeline behind themain valve.

At that moment pressure above the diaphragm islower then the pressure ahead of the main valve, themembrane will move up and change the position ofthe valve to open. In this way, the pilot valve controlsthe main valve.

The degree of valve lift depends on the pressurebehind the valve (pressure regulated), which is leadunder the diaphragm pilot valve that balances withthe spring over memebrane. Compaction of springscan be changed on the spot. Speed of opening andclosing of the main valve is set by the choke valve PS.

RP series valves are made for nominal pressure PN6,PN10, PN16 and PN25.

They come in flanged or screw connection:

Screw connection: from R1" to R2"Flange connection: from DN50 to DN300

Maximum fluid temperature is 120C

This valve can be lead into a fully open or fullyclosed position with ball valves S1 and S2. If thevalve S1 is closed, the valve is lead into a fully openposition, if the valve S2 is closed, the valve has beentranslated into a fully closed position.

All inside parts are made of stainless material(stainless steel and Teflon) and housing is made of acast steel or cast iron.

The pilot valve is made of stainless steel.
