Butterfly valves / LIANGGU
Flanged Stainless Steel Butterfly Valve
This model is a butterfly valve distinguished by integral flanged ends that provide defined bolting and line-support interfaces. 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 face-to-face dimension and shaft design
Typical applications
cooling water, large utility headers, process liquids, and pump-station isolation
Selection priorities
flange drilling, face-to-face dimension, shaft design, seat retention, line load, and actuator mounting
