WEH® Pressure Relief Module TVS20 for mounting into pressure plants to protect the vacuum pump, for inhouse venting, for inert/flammable gases, threaded connection, M24x2

Vacuum pressure relief module for inhouse venting for vacuum pump protection

The WEH® TVS20 Vacuum pressure relief module is designed to protect components operated under vacuum such as vacuum pumps, sensors etc. from overpressure. If, for example, a vacuum pump is installed in a pressure system which has a significantly higher pressure than the allowable operating pressure of the vacuum pump, the WEH® TVS20 protects the pump from damage by safely venting the overpressure into the space. Even short-term inlet pressures up to 420 bar are safely relieved in the TVS20 pressure relief module up to an overpressure of 0.2 bar in the outlet to the vacuum pump.

Suitable for pressure systems with a maximum inlet pressure of 420 bar and a nominal bore of up to 12 mm.

Various adaptors for inlet ‘B1’ are available for connecting the vacuum pressure relief module to the system.
