BERMAD 700 & 800 Series,Control Valves for Waterworks & Industrial Applications

At the heart of BERMAD’s waterworks activities, covering every water supply and distribution system application, is the BERMAD700 Series line of control valves and its high-pressure version, the 800 Series. Developed by BERMAD's creative engineeringand based on cutting-edge technologies, these Series offer a variety of control features from pressure reducing, relief andsustaining; through level, pump, surge, flow and burst control; to solenoid and electronic control. Optimally designed andexpertly integrated by BERMAD engineers into systems providing just the right models and configurations, the BERMAD 700& 800 Series control valves meet every national, regional, and municipal water supply need, as well as the special needs ofindustrial facilities, high-rise and public buildings, and luxury hotels.

For National, Regional and Municipal Distribution Networks, system design and operation starts with careful examinationof expected flow and pressure ranges, the parameters that determine major system components, including pump stations,reservoirs, supply lines, water treatment plants and desalination systems. These components are then integrated into pressurezones with leakage reduction means, to ensure a continuous, reliable and smooth supply of waterthrough an efficient and cost-effective network.

For Industrial Facilities, a reliable, uninterrupted supply of water is vital. When production processes rely on a high flow ofhigh-quality water at a constant flow and temperature, any interruption or deviation can be devastatingly costly. Where firehazards are in close proximity to workers, expensive equipment, or residential areas, absolutely reliable large-scale, self-supply,backup systems are a must.

High-Rise Buildings have unique requirements, which must be taken into accountwhen designing and installing their water supply and distribution systems.BERMAD solutions give careful consideration to issues such as:■ While single source supply is common, supply cut-off is unacceptable.■ Water damage in a high-rise building can be extremely costly.■ Valves are often located in close proximity to prestigious residential and office space.■ The main supply line is exposed to increasingly high head at lower zones.■ A multiplicity of systems requires integration and control.■ Maintenance personnel are not always skilled with control valves.

BERMAD is a world leader in its field with major market shares in North and South America, Europe, Asia, Africa, and Australia.The breadth of BERMAD’s activities, through its subsidiaries, representatives and customers, allows us to stay close to ourmarkets, continuing to increase and develop one of our most important assets - the accumulated know-how covering a rangeof systems, applications, and ideal solutions customized to every need.

This catalogue is intended to be a useful working tool for project investors, consulting engineers, construction supervisors,installation contractors, and maintenance personnel.

Luxury Hotels have all the special requirements of high-rise buildings,with the additional requirement of catering to high-water-consumptionfacilities such as jacuzzis, spas, swimming pools, artificial waterfallsand fountains. These systems typically handle aggressive water withcorrosive materials, while needing to operate very accurately underlow-pressure conditions. Any system failure is a breach of customerservice, which in the hospitality industry is totally unacceptable.

All the above systems require a multitude of valves with a variety of control features, construction materials and pressure ratings.BERMAD’s double-chambered 700 and 800 Series control valves are built from optimal materials to provide long-term operatingreliability under extremes of pressure, while allowing easy inline maintenance. The culmination of BERMAD’s experience andknow-how, the 700 and 800 Series ensures a smooth and reliable water supply, with efficient and integrated system operationbacked by BERMAD’s professional engineering support.

BERMAD Waterworks

The basic Model 700/705 diaphragm-actuated and the 800/805piston-actuated valves are hydraulically-operated, globe valves in eitherthe standard oblique (Y) or angle pattern design. Each valve comprisestwo major components: the body-seat assembly and the actuatorassembly.

The actuator assembly is unitized and is removable from the body asan integral unit. It consists of both an upper and a lower control-chamber.Each basic valve can easily be configured, on-site, either as asingle-chamber control valve (Model 705/805), or a double-chambercontrol valve (Model 700/800). The shaft sub-assembly, in both singleand double-chambered versions is center-guided, providing anunobstructed seat area.

The Model 700/800 Basic double-chambered valve operation isindependent of valve differential pressure since the line pressure actuallyserves as the actuator differential pressure. This develops maximumpower, ensuring immediate valve response. The upper control-chamberis pressurized to close, and vented to open the valve. The lower control-chamber is usually vented to the atmosphere, but can also be pressurizedto power the valve open.

The Model 705/805 Basic Valve uses valve differential pressure to powerthe actuator open or closed. The lower control-chamber, which servesto cushion the closing of the valve, is exposed to the downstreampressure, through a fixed orifice connected to the downstream side ofthe valve. The pressure in the upper control-chamber varies, usuallyresulting from the combined action of a regulating pilot and a fixedorifice. This varying pressure modulates the valve to open or close.

The Basic Hydraulic Valve is available in a wide range of materials, sizes,pressure ratings, and end connections. Single or double-chamberedversions are used as the main valve in all 700 and 800 Series applications.

Closed PositionThe closed adjustable pilot valve trapsline pressure in the upper controlchamber. The resulting superior forcemoves the valve to the fully closedposition and provides drip-tight sealing.

Modulating PositionThe pilot valve senses line pressurechanges and opens or closesaccordingly. It controls the accumulatedpressure in the valve upper controlchamber, causing main valve tomodulate to an intermediate positionand maintain the preset pressure value.

Open PositionThe open pilot valve releases linepressure from the upper control chamber.The line pressure acting on both thelower control chamber and the seal-disk,moves the valve to the open position.

Modulating Mode

Powered Open PositionLine pressure is applied to the lowercontrol chamber as pressure in the uppercontrol chamber is vented. This, togetherwith the line pressure acting on theseal-disk, creates a force that powersthe valve to the open position.

On-Off Modes

Closed PositionLine pressure applied to the uppercontrol chamber of the valve creates asuperior force that moves the valve tothe closed position and providesdrip-tight sealing.

Open PositionDischarging the pressure in the uppercontrol chamber to atmosphere or someother lower pressure zone causes theline pressure acting on the seal-disk tomove the valve to the open position.

Principle of Operation

* All text written above is valid for both 700 and 800 Series.



7

[1] - Double-Chambered Actuator■ Actuator assembly can be removed as one integral unit■ Simple on-site conversion to single-chambered■ Same valve body accepts both actuators (Diaphragm and Piston)

[2] - Diaphragm AssemblyThe flexible, unshaped, nylon-reinforced diaphragm is supported over the majority of its surface.Diaphragm load is limited to only the stretching forces applied to the active area.

[3] - Piston AssemblyVented lower chamber provides differential piston principle of operation and air cushioning. Constant active area togetherwith the sturdy construction and unobstructed long travel ensures stable and accurate regulation. The “shaft diameter”central guiding and the dynamic piston-seal reduce friction and jamming risk.

[4] - Cover PlugEnables on-site retrofit of:■ Indicator [4A]: For visual valve position indication■ Limit Switch: For signaling valve position.■ Position Transmitter: For analog transmission of valve position.

[5] - Inherent Separation PartitionThe inherent separation includes the bearing [5A], which provides complete central guiding for the valve moving assembly.The separation partition separates the lower control chamber from the flow in both the single-chambered, andthe double-chambered configurations.

[6] - SpringRequired for single-chambered configurations. Superfluous for double-chamberedconfigurations (unless check feature is required).

[7] - Seal Disc AssemblySelf-aligning, seal disk assembly provides balanced, free movement and a resilient seal for perfect, drip-tight sealing. It enables using several variations of seals and plugs for a wide range of applications and working conditions.

[8] - SeatStainless steel, raised, replaceable in-line and on-site.

[9] - Wide Body (“Y” or Angle pattern)Hydro-dynamically designed for efficient flow with minimal pressure loss and excellent resistance to cavitation. Full bore,valve port area clear of obstructions; no ribs or stem guides. Increases capacity by 25% over standard globe valves.

[10] - End ConnectionsConforms to pressure ratings and standards of: ISO, ANSI, JIS, BS, and others.

Valve Plug OptionsFlat disc“Quick opening plug”: Standard plug provides high flow and quickresponse.

Throttling PlugA throttling plug is used in order to provide more accurate, stableand smooth response for pressure and flow regulation while reducingnoise and vibration. Two types are available:“U” shape (standard) and “V” shape.

Applications■ Flow and leakage reduction■ Cavitation damage protection■ Throttling noise reduction■ Burst protection■ System maintenance savings

Pressure-Reducing ValvesEstablishing various pressure zones is one of the most common means to achieve balance in water transmissionand distribution networks. Pressure-Reducing Valves (PRV) “force” the dynamic parameters of the supply systeminto a constant predetermined delivery pressure. “Active PRV”, through definition of minimum required pressureat each pressure zone’s critical point, enables continuous readjustment of delivery pressure. This allows thesystem to work at a lower average pressure.

Model 740

Model 840

Model 840

Applications■ Isolation of pump start-and-stop effects from system, for:

❑ Solitary single speed pumps❑ Battery of single speed pumps (add and switch)❑ Battery of variable speed pumps (add)

13

Booster Pump Control ValvesPump Control Valves protect pumps, pipelines, and other system components by isolating the pipeline from thesudden velocity changes associated with pump starting and stopping. The “Active Check Valve” logic of operationis a pumping-system control method that prevents the system from experiencing surges rather than eliminating them.

The Model 740 Booster-Pump Control Valve is a hydraulically operated,diaphragm-actuated, active check valve that opens fully or shuts off in responseto electric signals. It isolates the pump from the system during pump startingand stopping, to prevent pipeline surges.

The Model 840 piston-actuated Booster-Pump Control Valve enables operationat high-pressure pumping systems. It extends the pressure-rating rangeupper-limit to 40 bar (600 psi).

Model 740



14

Surge Anticipating ValvesAbrupt pump stopping is followed by a pressure drop as the water column continues traveling along the line.The returning column hits the closed pump check valve, creating a high-pressure surge-wave, which travels atup to 4 Mach. Eliminating such a surge requires anticipation and pre-action. Surge Anticipating Valves react tothe pressure drop, accepting the returning column while already open, thus eliminating the surge.

Applications■ Eliminates surge for all pumping systems:

❑ Booster and deep well, single & variable speed■ Eliminates surge for all distribution networks:

❑ Municipal, high-rise buildings, sewage, HVAC, irrigation❑ Difficult to maintain, remote locations, older systems

Model 735-M

The Model 735-M Surge-Anticipating Valve is an off-line, hydraulically-operated,diaphragm-actuated valve. The valve, sensing line pressure, opens in response to thepressure drop associated with abrupt pump stoppage. The pre-opened valve dissipatesthe returning high pressure wave, eliminating the surge. The Model 735-M smoothlycloses drip-tight as quickly as the relief feature allows, while preventing closing surge.The valve also relieves excessive system pressure.

The Model 835-M piston-actuated Surge-Anticipating Valve enables operationat high-pressure pumping systems. It extends the pressure-rating range upper-limitto 40 bar (600 psi).

Model 736

16

Applications■ Pump overload & cavitation protection■ Safeguarding pump minimum flow■ Emergency filter by-pass■ Balancing between circuits in HVAC systems

The Model 736 Differential-Pressure Sustaining Valve is a hydraulically- operated,diaphragm-actuated, control valve that sustains minimum pre-set, differential pressurebetween two points regardless of fluctuating flow or varying upstream pressure.

Differential-Pressure Sustaining ValveDifferential-Pressure (∆P) Sustaining Valves are well suited for:■ Pumps with varying suction pressure regimes that require constant ∆P as overload & cavitation protection.■ Filtration Systems upstream from firewater networks that require a bypass to progressively

compensate for excessive demand.■ Air Conditioning Systems with varying demands that require constant ∆P between distribution

and collection lines.



Flow Control ValvesSystem design starts from expected flow range that determines pump-stations characteristics and location,supply lines layout and size, reservoirs location and volume, etc. Significant deviation from designed flow rangemight disrupt water supply or even damage system components. Appropriate design, placement, and use ofFlow Control Valves protect the system from excessive flow.

Applications■ Securing design specifications■ Prioritizing main system over sub-system■ Limiting consumers over-demand■ Maintaining pre-set maximum flow through filters■ Pump overload and cavitation protection

The Model 770-U Flow Control Valve is a hydraulically operated, diaphragm-actuated, control valve that maintains pre-set maximum flow, regardless offluctuating demand or varying system pressure.
