Priority valve double-pipe VVZ

This VdS approved 6/2 way priority valve is used in OPEN/CLOSE controls. There it connects two CO2 OPEN lines or one compressed air line and one CO2 OPEN line. The CLOSE line of the SHEVS unit exhausts automatically.

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 and VZ inlets will be closed off. The SHEVS return line connected to the CZ outlet exhausts at the same time.

For pipe connection of the valve, five 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.
