China Sanitary Pneumatic Control Divert Valve

Specifications

sanitary pneumatic reversing valve/change valve/shuttle valve/ directional valve
HS Code:8481804090


TECHNICAL PARAMETER:
1.Application:
This valve is sanitary, automatic or manual handle valve, widely used in food, beer, beverage, dairy products, cosmetic, pharmacy and biology engineering field.

2.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.
3.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 .

4.Material:
Steel parts:Stainless steel 304 or Stainless steel 316L
Sealing: EPDM. (standard)
SILICON,FDM, HNBR(CHOOSE).


5.Advantages:
Sealings:Excellent acid proof, alkali proof and high temperature performance. little degree of permanent compression deform.
Investment forging valve plug: Pressure durability less than 1.2MPA, metallographic structure beeter than casting ones.
Appareant design: Keep updated with international fashion style.
Cost performance: Impor substituted, cost saved and reiableoperation.

6.Connection types:

Welded.
Clamped
Screw or threaded, male part or female
welded - srew
Flange
To assure the connection and substitution with imported facilities, all the connecton styles withe pipe or equipment are made to DN11850, IDF / ISO, SMS 3A international standard size.
