One Way Type Vacuum Valve RSV,Vacuum Check Valve With Copper Material
One Way Type Vacuum Valve RSV,Vacuum Check Valve With Copper Material
1. Introduction and application
-
The one-way valve is provided with a return spring, which is used for maintaining the vacuum degree of the conveying system when the power supply fails or the vacuum generating device fails.
-
As a valve seat, the one-way valve has a wide nominal diameter range and a very small size.
-
Close the vacuum tube, for example, the valve can maintain the vacuum degree of the whole system when power is suddenly cut off, and the nominal flow rate can be from extremely low to extremely high, which is suitable for use in narrow spaces.
