9200 Series Isolation Valve
9200 Series Isolation Valve Double Block & Bleed
This two-way, solenoid operated, pilot controlled isolation valve meets the requirements for a fast acting, high temperature shutoff valve for use on GE Energy, Pratt & Whitney, Rolls-Royce, and other turbine engines.
There is a single main stage inlet port, an outlet port, and a pilot stage vent port. The valve is used to rapidly shut off gas fuel flow upstream of the gas control valve in the event of a turbine trip condition. The valve then isolates the fuel source from the turbine engine.
The 9200 Series Isolation Valves come in the 120 VDC and 24 VDC versions The units are certified to ATEX EEx d IIB+H2 T3, UL/CSA/FM Class I, Div. 1&2, Groups B,C,D. The valve can be used with air, natural gas or liquid fuels. Y&F's 9200 Series Isolation Valves are NACE compliant. Available in Double Block & Bleed.
