Design features
guided shutoff geometry engineered for controlled flow and isolation in thermal plant piping
Final dimensions, materials, ratings and documentation depend on the approved configuration.
Power station valves / LIANGGU
Power Station Globe Valve
For projects that need steam drains, feedwater branches, condensate systems, sampling lines, and auxiliary services, the Power Station Globe Valve provides guided shutoff geometry for controlled flow and isolation in thermal plant piping. 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 linear stem moves a guided disc or plug toward a stationary seat; the tortuous flow path creates more pressure loss than a gate valve but supports controlled shutoff and, with suitable trim, limited regulation; verify plug and seat design
Typical applications
steam drains, feedwater branches, condensate systems, sampling lines, and auxiliary services
Selection priorities
pressure drop, plug and seat design, flow direction, erosion allowance, cycle rate, and handwheel or actuator sizing
