Electric Power Station Gate Valve
This model is a gate valve distinguished by motor-operated isolation with torque and limit protection for remote power-plant control. For a project quotation, share the required size, pressure designation, materials, seating, connections and quantity. Final suitability is confirmed against the approved specification.
PRODUCT DETAILS
Understand this valve.
Working principle
a stem moves a wedge or parallel gate clear of the bore for isolation; the valve should normally be fully open or fully closed, not used as a routine throttling device; verify closing time and power supply
Typical applications
boiler systems, turbine auxiliaries, high-energy piping, and interlocked isolation points
Selection priorities
actuator duty, closing time, power supply, torque margin, stem thrust, control signals, and emergency operation
