PNEUMATIC ACTUATION, INBAL PRESSURE CONTROL DELUGE VALVE

Описание: PNEUMATIC ACTUATION, INBAL PRESSURE CONTROL DELUGE VALVE
The Inbal Deluge Valve has the ability to control the flow into the protected area by controlling the downstream pressure. When one or more of the sprinkler heads located on the pilot line fuses, the Inbal Deluge Valve opens and water flows from all open nozzles.
The Pressure Control Inbal Deluge Valve, when in operation, automatically controls the Outlet pressure to a pre-set delivery pressure which remains steady and unaffected by the variations or fluctuations of the Inlet Line pressure.
Turning the pressure control Pilot Valve Adjusting Screw clockwise increases downstream pressure and counter-clockwise decreases the downstream pressure.
Once the Inbal Deluge Pilot Valve operates, it latches in an open position, preventing the Inbal Pressure Control Deluge Valve from closing even if the open releasing dry pilot line closes. The Inbal Valve will close only when the Resetting is done.
As soon as the releasing system and the sprinkler piping are reset, to reset the Inbal Deluge Valve, pull the Deluge Pilot Valve Latching mechanism Reset Knob and insert the Resetting Indicator to hold the Reset Knob @ a pulled out position.
Open the air supply source Valve. As soon as the air /pneumatic pressure exceeds the level required by the Deluge Pilot Valve equipped w/ Latching mechanism for “set” position, the Resetting Indicator falls off hung by the Security Chain.
