At the point of reversing valve

Apply 

 ▪ The directional valve is a sanitary single-seater and two-seat pneumatic valve, which is widely used in the food processing industry, beverage production, pharmaceutical and fine chemical industry. 

 Operating principle 

 ▪ The reversal valve series is operated remotely through compressed air. By controlling the relative position of the spool, the purpose of opening or closing the valve is to change the flow direction of the medium (reversing type). 

 ▪ The manual cut-off single-seat valve series changes the flow direction of the medium (reversing type) through the control of the handle. 

 Material 

 ▪ Product overflow steel parts: 304/316L 

 ▪ Other steel parts: 304 

 ▪ Seals for contact with conveying materials: E P D M 

 ▪ Internal surface treatment: R a ≤ 0. 4 μ m 

 ▪ External surface treatment: sandblasting, polishing 

 Technical parameter 

 ▪ Large product pressure: 10 0 0 k p a (10 b a r) 

 ▪ Small product pressure: vacuum 

 ▪ Temperature range: -10°C~13 5°C (using a sealing ring made of EP D M) 

 ▪ Pressure: 40 to 8 0 0 k p a (4 - 8 b a r) 

 Function of the operative device 

 ▪ Move down through aerodynamic mode, and the spring is reset. 

 ▪ Move up through aerodynamic means, and the spring is reset. 

 ▪ Move up and down through pneumatic means (A/A).
