Welcome to Shanghai Mengsheng Sheng International Trade

 

 

Name: KF series high vacuum electromagnetic pressure differential inflation valve
 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Description :

 

This series of valves is a specialized valve installed on mechanical vacuum pumps and connected to the same power source as the pump. The opening and stopping of the pump directly controls the opening and closing of the valve. When the pump stops working or the power is suddenly interrupted, the valve can rely on the pressure difference between the atmosphere and vacuum to automatically close the vacuum system, maintain its vacuum degree, and fill the atmosphere into the pump chamber through the throttle hole of the valve and the pump inlet, thereby avoiding pump oil backflow and pollution of the vacuum system. During the valve operation, only a very small amount of gas is filled into the vacuum chamber, so the vacuum degree affecting the vacuum chamber is extremely small. It also has the advantages of smooth operation, small volume, reliable use, sealing performance, and long service life. The medium of the valve is air and non corrosive gases.

Characteristic:
1.Simple structure, easy to replace and maintain;
2.Easy to clean design;
3.Pressure structure design, when the valve is opened or closed, only a very small amount of gas is filled into the vacuum chamber.

Basic Specifications:
Scope of application: 1 × 102A~1.2 × 10Pa
