Design features
a reinforced body and engineered trim selected for substantial differential pressure
Final dimensions, materials, ratings and documentation depend on the approved configuration.
Control valves / LIANGGU
High Pressure Control Valve
This model is a control valve distinguished by a reinforced body and engineered trim selected for substantial differential pressure. 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
the actuator positions an engineered trim to change flow; correct sizing depends on required capacity, installed pressure drop, process dynamics, phase behavior, noise, and the specified fail action; verify phase change and erosion
Typical applications
boiler feedwater, injection systems, gas pressure reduction, and high-energy process control
Selection priorities
inlet-outlet pressure, phase change, erosion, staged pressure drop, actuator thrust, noise, and outlet velocity
