Priority valve double-pipe

• VdS approved 6/2 way priority valve for use in OPEN/CLOSE controls. Valve connects two CO2 OPEN lines, or one compressed air and one CO2 OPEN line. The CLOSE line of the RWA unit exhausts automatically

• In normal state, inlet VA is connected to outlet CA, and inlet VZ to outlet CZ. When pressure is admitted to the CO2 inlet, the valve reverses, connecting the CO2 inlet to outlet CA. Inlets VA and VZ will be closed off. The RWA return line connected to outlet CZ exhausts at the same time

• Control pressure for CO2 inlet min. 4bar

• Maximum operating pressure 80bar

• Ambient temperature range: -25°C to +110°C

• Nominal bore (free cross section) of valve 4mm VVZ with male connectors

• VdS approval no. G 590014

• For pipe connection of the valve, 5 male connectors 1/8" (e.g. B1-6 1/8) will be required additionally

Design of the SHEVS may require reliable venting of the piping.
