Priming Restriction


The Priming Restriction is a flow restriction component used as an integral orifice in the control trim of BERMAD Deluge Valves.

In addition it incorporates two ¼” NPT (F) ports to enable a priming pressure connection to supplementary instruments like a solenoid or relay valve.

The internal restriction orifice is available in a number of diameters, each suited to a particular valve/pilot size.
