IR-430-XZ

The BERMAD Model IR-430-XZ Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that it sustains minimum preset upstream (back) pressure regardless of fluctuating flow or varying downstream pressure.

IR-743

The Model 743 Booster Pump Control & Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated active check valve that opens or shuts off in response to electric signals. It isolates the pump from the system during pump starting and stopping, to prevent pipeline surges. While open, it sustains minimum discharge pressure regardless of fluctuating … read more

IR-430-55

The BERMAD Model IR-430-55 is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions. When installed in-line, it sustains minimum preset upstream (back) pressure. When installed as a relief or circulation valve, it relieves line pressure in excess of preset. The BERMAD Model IR-430-55 either opens or shuts in … read more

IR-740-2S

Double chambered, hydraulically operated, active check pump control valve that opens fully or shuts off in response to electric signals. The valve isolates the pump from the system during pump startup and shutdown, thereby preventing pipeline surges. BERMAD 700 SIGMA EN/ES series valves are hydraulic, oblique pattern, globe valves with a raised seat assembly and double chamber unitized actuator, … read more

IR-430-55-KX

The BERMAD Model IR-430-55-KX is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting. It either opens or shuts in response to an electric signal.

WW-740-M5/M5L/M6

Double chambered, hydraulically operated, active check pump control valve that opens fully or shuts off in response to electric signals. The valve isolates the pump from the system during pump startup and shutdown, thereby preventing pipeline surges. The BERMAD 700 Series large size control valves are hydraulically operated, diaphragm actuated type. Unique hydro-dynamic globe valve … read more

IR-730

The Model 730 Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions. When installed in-line, it sustains minimum pre-set, upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. When installed as a circulation valve, it relieves excessive line pressure when above maximum pre-set.

WW-743-M5/M5L/M6

Hydraulically operated, pump control, pressure sustaining & reducing 3-Way control valve. It opens/closes in response to electric signals, isolating the pump from the system during startup and shutdown, thereby preventing pipeline surges. While open, it sustains minimum pump discharge pressure to ensure optimal pump operation. It also reduces upstream pressure to lower constant downstream pressure. … read more

WW-740 EN/ES

Double chambered, hydraulically operated, active check pump control valve that opens fully or shuts off in response to electric signals. The valve isolates the pump from the system during pump startup and shutdown, thereby preventing pipeline surges. BERMAD 700 SIGMA EN/ES series valves are hydraulic, oblique pattern, globe valves with a raised seat assembly and … read more

IR-130-XZ

The BERMAD Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting.

IR-730-55

The Model 730-55 Pressure Relief/Sustaining Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that sustains minimum pre-set, upstream (back)pressure regardless of fluctuating flow or varying downstream pressure. It also either opens or closes in response to an electric signal. When installed as a circulation valve, the Model 730-55 relieves excessive line … read more

WW-743 EN/ES

Hydraulically operated, active check, pump control & pressure sustaining valve with two independent functions: It opens fully or shuts off in response to electric signals, isolating the pump from the system during pump startup and shutdown, thereby preventing pipeline surges.While open, it sustains minimum pump discharge pressure regardless of fluctuating flow, and prevents the pump … read more
