Pneumatic Actuated Butterfly Valve
This model is a butterfly valve distinguished by a pneumatic quarter-turn actuator for fast, repeatable remote operation. 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 spring-return or double-acting mode and cycle time
Typical applications
automated water skids, air handling, process utilities, and emergency or batch isolation
Selection priorities
air pressure, spring-return or double-acting mode, cycle time, solenoid voltage, torque margin, and position feedback
