Heavy Gauge Steel, Stainless Steel or Aluminum Construction
Manual, Air or Electric Actuated Operation
Optional Limit Switches

Double Flap Gate Vales

Double Flap Gate Valves are designed for high-pressure applications up to 20 PSI and high temperature extremes. Available in both the "short", low profile HPSC model and the "tall", high- profile HPTC model. Both models are offered with a choice of pneumatic, electro-mechanical or gravity/counterweight actuation. A triple flap gate configuration is also available if better suited for your particular application.

8" to 18"+ Sizes Available
