8413 Series Liquid Fuel Stop Valve Assembly
The YF 8413 Series Three-Way Fuel Oil Stop Valve and Actuator Assembly provides on/off control of liquid fuel for large industrial turbines and is CE/PED approved.
The valve is normally closed to turbine and is held in the bypass position with a spring. A hydraulic cylinder provides the opening force for the valve by overcoming the spring force, fluid forces and friction and allowing flow to the turbine. The valve is hydraulically tripped to allow hydraulic pressure to be dumped during a trip function which closes the valve to the turbine. A limit switch which is normally closed, opens when flow is allowed to the turbine.
