Design features
offset geometry that creates cam-like separation between the sealing surfaces; detailed geometry must be confirmed for the selected design
Final dimensions, materials, ratings and documentation depend on the approved configuration.
Butterfly valves / LIANGGU
Triple Eccentric Metal-Seated Butterfly Valve
This model is a butterfly valve distinguished by triple-offset sealing geometry that separates the sealing surfaces during opening. 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 seat torque and sealing direction
Typical applications
high-temperature steam, hydrocarbons, utilities, and applications needing low-rubbing metal sealing
Selection priorities
offset geometry, seat torque, sealing direction, temperature expansion, leakage class, and actuator travel stops
