Anderson Greenwood Series 9300 Pilot Operated Safety relief Valve
The Series 9300 employs the highly successful pressurized PTFE film seat, as well as protected FEP diaphragms. The design allows these valves to be used in the pilot operated pressure relief mode and simultaneously provide vacuum relief, either via weight loads of the internals, or with a specific pilot control of the vacuum opening. The Series 9300 was designed with a special studded inlet connection to reduce the inlet profile, and coupled with larger orifice areas, these valves provide flow capacities as much as 45% greater than the Series 90 valves. The Series 9300 is a full body valve to pipe away the discharge if required.
