Description
WEH® Pressure Relief Module TVS21 Series
The WEH TVS21 vacuum pressure relief moduleprotects vacuum pumps even more effectively against damage from residual pressures in high-pressure systems.

Where a vacuum pump is fitted into a pressurised system that operates at a substantial higher pressure as the permitted operating pressure of the vacuum pump, the TVS21 pressure relief module protects the pump from damage.

If excessive pressure should build up, the vacuum check valve opens and allows the excess pressure to dissipate into the atmosphere.
Even short-lived bursts of inlet pressures up to 6,000 psi (420 bar) can be safely dissipated using the TVS21 pressure relief module up to an excess pressure of 0.2 bar at the outlet to the vacuum pump.

The adaptor for inlet “B” is available with a threaded or welded connection.
