Bermad IR-450-60-R Level Control Valve



Bermad IR-450-60-R Level Control Valve

The Bermad Model IR-450-60-R Level Control Valve with Modulating Horizontal Float is a hydraulically operated, diaphragm actuated control valve. The valve hydraulically controls reservoir filling to maintain constant water level, regardless of fluctuating demand.

The Needle Valve allows continuous flow from Valve inlet into the Control Chamber. When water level rises, it pushes the Float up throttling the Float Pilot. Pressure in the control chamber accumulates, causing the Valve to throttle closed, reducing filling rate, and eventually closing drip tight. Should level fall, the float pilot releases pressure from the control chamber causing the Valve to modulate open. The needle valve controls Valve closing speed. The Cock Valve enables manual closing.
