a compact body clamped between pipeline flanges for economical quarter-turn isolation
Final dimensions, materials, ratings and documentation depend on the approved configuration.
Butterfly valves / LIANGGU
Wafer Type Butterfly Valve
This model is a butterfly valve distinguished by a compact body clamped between pipeline flanges for economical quarter-turn 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 shaft rotates the disc through a quarter turn; seat geometry, differential pressure, flow direction, line velocity, cycle frequency, and actuator torque determine shutoff and control performance; verify disc corrosion resistance and dead-end suitability
Typical applications
water treatment, HVAC, air systems, light process service, and space-constrained skids
Selection priorities
liner material, disc corrosion resistance, dead-end suitability, alignment, bolt clearance, and flange standard
