Bermad IR-130-59-3W-X Pressure Sustaining valve



Bermad IR-130-59-3W-X Pressure Sustaining valve (for filters)

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

The de-energized Solenoid drains the main valve control chamber, causing the main Valve to open wide, energizing the solenoid activates the Pressure Sustaining Pilot, which commands the Valve to throttle should Upstream Pressure drop below pilot setting, and to modulate open when rises above it.
