Butterfly valves / LIANGGU
Electric Actuated Butterfly Valve
This model is a butterfly valve distinguished by an electric actuator giving remote positioning and open-close control. 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 travel time and manual override
Typical applications
water networks, HVAC, utility automation, cooling systems, and unmanned valve stations
Selection priorities
modulating or on-off duty, travel time, manual override, torque switch, communication, power supply, and enclosure rating
