The Double Acting Angle Seat Valve uses compressed air for both opening and closing, offering precise control without relying on spring tension. Its signature Y-pattern body allows for high flow rates and low pressure drops compared to globe valves.
Operation: Air drives the piston in both directions, ideal for high-viscosity fluids.
Durability: The stem seal is self-adjusting, handling millions of cycles.
Safety: Unlike spring-return types, it remains in its last position during air loss.
Technical Attributes: Double Acting Pneumatic Angle Seat Valve
1,Actuation Mode,Double Acting (DA); requires air to open and air to close.
2,Body Design,Y-Pattern (Angle Seat) for high flow and minimal turbulence.
3,Actuator Material,Stainless Steel (for hygiene/corrosion) or Polyamide (PA).
4,Body Material,CF8M (316) or CF8 (304) Stainless Steel.
5,Sealing Material,PTFE (Teflon) as standard; suitable for high temperatures.
6,Stem Seal,Self-adjusting V-ring packing with spring compensation.
7,Pilot Pressure,Typically 3 to 8 bar required for reliable switching.
8,Working Pressure,Capable of handling up to 16 bar (232 psi) depending on size.
9,Media Temp.,Broad range from −10°C to +180°C (steam compatible).
10,Flow Direction,Can be installed over-seat or under-seat to prevent water hammer.
11,Fail-Safe Status,Last Position: Remains in its current state if air supply fails.
