Orifice Plate Assembly Orifice Plate Assembly

When an orifice plate assembly is used as an integral part
of a flow control valve control circuit, it provides the differential
pressure (∆P) to power the flow control pilot. The opening and
closing of the pilot causes the flow control valve to throttle
Total head loss across the valve is reduced by locating sensing
ports close to the orifice plate, to sense downstream pressure
before it recovers.
The orifice plate internal diameter is calculated and machined
according to valve size and required flow limitation
