Priority valve single-pipe VVE

This VdS approved 3/2 way priority valve connects two CO2 lines or one compressed air line and one CO2 line.

In normal state, the VA inlet is connected to the CA outlet. When pressure is admitted to the CO2 inlet, the valve reverses, connecting the CO2 inlet to the CA outlet. The VA inlet will be closed off.

For pipe connection of the valve, three male connectors 1/8″ (z. B. B1-6-1/8) will be required additionally.

The design of the SHEVS may require reliable venting of the piping.
