Some of your choices of models in the 700 Series include...

Pressure Reducing Valve - The Model 720 Pressure Reducing Valve reduces higher upstream pressure to a lower preset downstream pressure regardless of changes in inlet pressure and or flow rates.  UL approved for fire protection services.

Pressure Reducing & Pressure Sustaining Valve - The Model 723 Pressure Reducing & Pressure Sustaining Valve has two independent functions.  It maintains a constant outlet pressure regardless of fluctuating flow rates and/or varying inlet pressure and it sustains a pre=set minimum upstream pressure.

Pressure Relief / Sustaining Valve - Model 730 Pressure Reducing Valve is an automatic control valve designed to relieve excess pressure or sustain a minimum upstream back pressure.  UL and FM approved for fire protection service.

Surge Anticipating Control Valve - The Model 735 Surge Anticipating Control Valve is designed to protect pumps and pipelines from pressure surge damage resulting from the sharp flow velocity changes associated with pump starting and stopping and especially with abrupt pump stoppages caused by power failures.

Pump Control Valve, Booster Type - The Model 740-Q Pump Control Valve, Booster Type is designed to be installed on the discharge of a booster pump to prevent pressure surges caused by the starting and stopping of the pump.

Modulating Float Control Valve - Model 750-60 and Model 750-67 are both Modulating Float Control Valves designed to maintain a constant water level in reservoirs and storage tanks.

Two Level, Non-Modulating Float Control Valve - The Model 750-66 Two Level, Non-Modulating Float Control Valve is an automatic control valve designed for low level and high level control of water in reservoirs and storage tanks.

Check Valve, Non-Slam Type - The Model 760-03 Non-Slam Check Valve is a hydraulically operated valve designed to open and close drip-tight in response to the differences in inlet and outlet pressures.

Rate of Flow Control Valve - The Model 770 Rate of Flow Control Valve is an automatic control valve designed to maintain a constant pre-set rate of flow regardless of changing system pressures and demand.

Altitude Control Valve, One Way Flow - The Model 780 Altitude Control Valve, One Way Flow is an automatic control valve designed to control the high water level in reservoirs and tanks without the need for external control devices such as floats.

Your special valve, Just ask!  Bermad can engineer and manufacture virtually any control valve function you might require in sizes 1 1/2" through 20".
