Power station valves / LIANGGU
Pressure Seal Power Station Globe Valve
This model is a globe valve distinguished by a pressure-seal bonnet paired with a guided globe trim designed for high-energy service. 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 cavitation or flashing risk and alloy grade
Typical applications
high-pressure steam, feedwater control bypasses, heater drains, and boiler auxiliaries
Selection priorities
trim velocity, cavitation or flashing risk, alloy grade, stem thrust, inspection interval, and bonnet seal
