Model IR-130-59-3W-X

The BERMAD Model IR-130-59 Is a hydraulically operated, diaphragm actuated control valve designed to maintain proper backwash pressure in filtration systems.
During normal irrigation the valve is wide open creating minimal pressure head loss and conserving pumping energy.
In response to an electric signal, supplied simultaneously to system flushing command, the IR-130-59 modulates closed, sustaining minimum preset upstream (back) pressure to filters manufacturer
recommendations.

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-120-XZ

The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure and opens fully upon line pressure drop.

IR-120-55-X

The BERMAD Pressure Reducing Control Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand, and opens fully upon line pressure drop. The BERMAD Model IR-120-55-X either opens or shuts in response to an electric signal.

IR-130-54-X

The BERMAD Model IR-130-54-X 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 is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of this command.

IR-172-50-bD

The BERMAD Model IR-172-50-bD is a hydraulically operated, diaphragm actuated control valve that performs three independent functions. It limits system demand to a preset maximum flow rate; it reduces downstream pressure to maintain a constant preset maximum, and it either opens
or shuts in response to a pressure command.

IR-130-50

The BERMAD Pressure Relief/Sustaining Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure. It either opens or shuts in response to a remote pressure command. When installed offline, the BERMAD Model IR-130-50 relieves line pressure in excess of preset pressure.

IR-170-50-bDZ

The BERMAD Flow Control Valve with Hydraulic Remote Control is a hydraulically operated, diaphragm actuated control valve that limits system demand to a preset maximum flow rate. It either opens or shuts in response to a remote pressure command.

IR-120

The BERMAD Pressure Reducing Valve is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure.

IR-120-55

The BERMAD Model IR-120-55 is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. It either opens or shuts in response to an electric signal.

IR-123-50

The BERMAD Pressure Reducing and Sustaining Control Valve with Hydraulic Remote Control is a hydraulically operated, diaphragm actuated control valve that performs three independent functions. It sustains the preset minimum upstream pressure, reduces downstream pressure to a constant preset maximum, and it either opens or shuts in response to a remote pressure command.
