Summary of electric pneumatic valve spool ball.
electric pneumatic valve spool ball is a kind of X to the vertical channel reversing pneumatic ball valve, it is mainly used for pipe line of truncated or through the media, the media in accordance with the procedures scheduled delivery to the designated point, namely the convenient and fast, achieve the effect of a pneumatic valve is multi-purpose. Electric pneumatic valve spool ball sphere is the feature of two channels for X to decorate, four channel diameter are actually sphere circular cross section on the equator, when the ball along the clockwise 90 & deg; , can make the similar of two channels to achieve two identical, for the two kinds of medium flow switch, alternative four pneumatic valves, simplify the procedures, convenient operation, good synchronization.
electric spool pneumatic ball valve structure features:
1, fluid resistance small, sphere and pneumatic valve connection pipe cross section are equal, and arc sphere channel adopted, medium through the sphere is, fluid resistance is small.
2, sealed performance is good: pneumatic seat USES the elastic deformation and high strength of PTFE material, good sealing performance to ensure the stability of pneumatic valve.
3, long service life: pneumatic valve pneumatic valve core and light see neck austenite stainless steel material, pneumatic valve seat of PTFE material selection, can achieve good corrosion resistance, extend the service life of the pneumatic valve.
