Power station valves / LIANGGU
Forged Steel Power Station Gate Valve
This model is a gate valve distinguished by forged pressure-containing parts engineered for compact high-integrity power-plant isolation. 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 NDE extent and hardness control
Typical applications
high-pressure drains, vents, startup lines, steam bypasses, and boiler auxiliaries
Selection priorities
bonnet construction, NDE extent, hardness control, traceability, forging grade, and weld-end preparation
