Pneumatic shuttle valve

The following is a comprehensive information summary about pneumatic shuttle valves, combined with technical parameters, application scenarios, and market data:

1、 Product Definition and Working Principle
Pneumatic shuttle valve is a gas pipeline control device that integrates a valve body and a pneumatic actuator. It achieves fast switching control of medium circulation through the reciprocating motion of a piston driven by compressed air. Its core function is to achieve dual gas source switching through logical "OR" function, with a switching time of ≤ 0.3 seconds, suitable for automation systems that require fast response.
2、 Core performance characteristics
Structural Design
The actuator and valve body are designed in an integrated manner, reducing the volume by 30% compared to traditional angle seat valves, and supporting installation at any position.
Adopting soft sealing technology (polyurethane/EPDM/FPM), the leakage level reaches DIN EN 12266 Class A.
Technical parameters
Interface size: DN20~DN200 (flange HG20592 or thread G3/8 "~G2").
Control pressure: 0.3-0.8MPa, medium temperature coverage -80 ℃ to+180 ℃.
Material options: The valve body is made of CF8M/CF8 stainless steel or WCB carbon steel, and the sealing material can be selected from fluororubber (high temperature resistance) or EPDM (steam resistance).
3、 Typical application scenarios
Industrial sector
Petrochemical industry: Explosion proof control system for dual gas source switching.
Air separation equipment: Addressing the need for rapid switching in pressure swing adsorption processes.
Special working conditions
Vacuum pipeline: The sealing performance meets the requirements of vacuum resistance (such as semiconductor cleaning equipment).
Corrosive medium: 316 stainless steel valve body is suitable for weak acid and weak alkali solutions.
