sanitary pneumatic reversing valve  技术参数 Location:Home > Product > Product Show

Working principle:

The working principle of pneumatic valve series is to change the enegy generated by the compressed air  into mechanical energy, the mechanical energy will drive the stem axial movement, will move the formation of the sealing parts location to control the swithch, and ultimately the medium will reverse or stay stable.

Technical datasheet:

I)New-style sanitary stop/switch valves possess more improved saftey.clearance.durability and appearance .
II) Having open supporter which separates the pneumatic actuator and valve body ,check the shaft seal directly .This design separates the gearing and the products parts,prevents the heat transfer from valve body to pneumatic device .
III) “NC”and “NO”functions can be instantly switched .
IV)Spherical valve body have ideal fluidity and clearance .
V)Dealing with material becomes much milder .
VI)Standard valve body design makes the joint style more flexible and various .
VII)Metal stop mechanism assures the long life of the seal .
VIII)Quick convenient assemble and maintainance operation .
