Yuy Food Grade Pneumatic Directional Valve

Specifications

sanitary pneumatic reversing valve/change valve/shuttle valve/ directional valve

HS Code:8481804090

 

TECHNICAL PARAMETER:

1.Application:

 

2.Working principle:

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

3.Technical datasheet:

I)  New-style sanitary stop/switch valves possess more improved safety.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 prevent the heat transfer from the valve body to the 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 maintenance 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. a little degree of permanent compression deforms. Investment forging valve plug: Pressure durability less than 1.2MPA,  metallographic structure better than casting ones.Apparent design: Keep updated with international fashion style. Cost performance: Impor substituted, cost saved and reliable operation.

6.Connection types:

1. Welded.ClampedScrew or threaded, male part or female welded - srewFlange

To assure the connection and substitution with imported facilities, all the connection styles withe pipe or equipment are made to DN11850, IDF / ISO, SMS 3A  international standard size.
