Pneumatic Flat Gate Valve
This model is a gate valve distinguished by a parallel flat gate combined with fast pneumatic actuation. 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 stem moves a parallel flat gate to open or close the flow path; the valve should normally be fully open or fully closed, not used as a routine throttling device; verify particle loading and actuator sizing
Typical applications
gas gathering, slurry-tolerant isolation, piggable lines, and automated skid packages
Selection priorities
bore geometry, particle loading, actuator sizing, air pressure, fail action, and seat-cleaning strategy
