BERMAD 700 SeriesSuperior Hydraulic Control Valves for FireProtection Systems

Bermad hydraulic control valves provide superiorperformance in On-Off operation or regulation offire protection systems, waterworks and industrialinstallations.

Bermad line of Fire Protection hydraulic valvesconsists of valves for a wide range of applicationsand constitutes a product line of impressivecompleteness. Its unsurpassed reliability has beenwell proven over many years of use throughoutthe world.

Bermad valves are complemented by acomprehensive range of control pilot valves andother control accessories for total flexibility ofapplication.

Advanced features include a unique valve body,hydrodinamically designed for high flow capacityand low pressure loss, and an optional heavy dutyDouble-Chambered actuator, which providespositive, immediate response with accurate control,and smooth valve action, without causing waterhammer.

Fire Hydrants and Monitor Valves

Bermad Model FP405-Z

The fast response of a fire protection system iscritical to its effectiveness. The minutes requiredfor full opening of a mechanical valve can be costly.

Bermad's Hydraulic Hydrant enables fast localoperation by a single twist of a control handle.

The valve can be utilized for operating a water/foammonitor or shutting off water lines. It can be easilyinstalled to replace a manual hydrant valve.

Dependability

Bermad Hydraulic Hydrant Valve does not jam,even after remaining closed over a long period oftime. There is no need to remove the valve fromthe line for servicing. The robust elastomers usedfor seals and diaphragm ensure long life cycle.

Pressure RegulatingHydrantBermad Model FP420

Bermad Pressure Regulating Hydrant is designedto protect the fire hose system against excesspressure by limiting maximum outlet pressure toa preset point, not exceeding 100PSI (6.9 Bar),according to NFPA-14 standard.

The Hydrant Valve maintains a fully controlledopening speed and flow capacity.

Fire Pump Control Applications

Fire Pump Pressure Relief Valve

Bermad Model 730-UL/FM

Bermad high performance Pump Relief valve isspecifically designed and UL/FM approved for fireprotection systems. The valve opens quickly to relieveexcess pressure in the system and maintains a constantpressure in the fire pump discharge, regardless offlow rate throughout the system.

A unique hydrodynamic design gives Bermad's valvea higher relief capacity than any competing relief valveon the market.

The hydraulic pilot system maintains a fixed reliefpressure with high accuracy and dependability,eliminating the typical leakage and jamming problemsfound in mechanical, spring-loaded relief valves.

Pump Suction Control Valve

Bermad Model 730-R

Bermad UL listed Pump Suction Control Valve wasdesigned especially for pressure control of fire pumpsuction in municipal or other water supply applications.

The valve operates automatically and ensures thatthe suction pressure will not fall below a pre-setminimum.

Pressure sustaining & Back Pressure valvefor in-line applications

Bermad Model FP730

Bermad Pressure Sustaining & Back Pressure Valveaccurately maintains a constant pre-set upstreampressure, regardless of changing upstream potentialor system demand.

Main Applications:

n Supplies available pressure above set point to lowaltitude areas.

n Modulates or closes to maintain minimum pressurein high altitude areas.

n Closes to prevent line drainage during power failureor flow stoppage.

Water Hammer and SurgeControlThe Surge Effect is very common in advanced firefighting systems requiring extremely rapid fire pumpactivation in order to provide high water pressureand flow.

Bermad supplies proven solutions to protect pumps,instrumentation and pipelines from dangeroussurges and pressure waves formed by flow changes.For this purpose, Bermad's Control Valve productline contains a number of models which areespecially adapted for use in fire fighting systems.

Pump Control Valve

Bermad Model FP740

When installed at the fire pump outlet, Bermad'sPump Control Valve inhibits start-up pressure surgesand eliminates unexpected shut-off surges.

Non-Slam Check Valve

Bermad Model FP760

Bermad Non-Slam Check Valve inhibits start-uppressure surge in fire pumps by controlling theopening of the hydraulic check valve and providesnon-slam operation during pump shutoff withdrip-tight sealing.

Pump Relief with Surge AnticipatingFeature

Bermad Model FP730-55

Combines fire pump pressure release feature withpre-opening feature to anticipate start up surge.

This combination is suitable for use with largevolume electric and diesel-powered fire pumps.

Other combinations of features are available.

Pressure Reducing Valve

Bermad Model 720-UL

Bermad UL Listed Pressure Reducing Valve functionsautomatically to reduce a high, unstable supplypressure and maintain a precise, stable, pre-setpressure regardless of changing upstream pressureor flow.

An optional unique V-port plug improves the valve'scapacity to cope with flow ranges far below today'snorm.

The valve's unique design endows it with quickreaction to system demands, and keeps pressureloss at the minimum.

Main applications:

n Hose station feeds where fire header pressureis over 100 PSI (6.9 bar), according to NFPA-14standard .

n Sprinkler systems where supply pressure isabove optimal.

n Deluge systems: in pulsing pressure, or wheresupply pressure is above system pressure rating,the valve will eliminate excessive flow rates andsurge damage.

n Foam systems: Bermad PRV will maintain theprecise water foam pressure designed for thenozzles.

n Fire hydrant water supply: prevents hoseover-pressure hazards, allowing the operator towork safely in pressure ranges below 100 PSI(6.9 bar), as specified by NFPA standards.

Reservoir Float Valves

Bermad Models 750-66/67

Bermad Float Valves open to fill reservoirs, tanksetc. When water rises to a predetermined level,float action will cause the pilot to close the mainvalve.

For cases in which a fully opened valve is requiredduring low supply pressure, a special model hasbeen designed with a 4-Way operation, enablingfull opening and complete closure at two defined,adjustable levels.

Altitude Valves

Bermad Model 780-AX

Bermad Altitude Valves control water level inreservoirs to prevent spills, without using externalcontrol devices such as floats etc.

An Altitude Valve will remain fully open until aclosing command is transmitted by an Altitude PilotValve.
