OPEN/CLOSE priority valve
- Priority valve for use in OPEN/CLOSE controls. Valve connects two CO2 OPEN lines, or one compressed air and one CO2 OPEN line. Furthermore, two CO2 CLOSE lines, or one compressed air and one CO2 CLOSE line are interconnected. Reciprocal venting must take place in the control valves for the OPEN/CLOSE function.
- In normal state, inlet VA is connected to outlet CA, and inlet VZ to outlet CZ. When pressure is admitted to the CO2A inlet, the valve reverses, connecting the CO2A inlet to outlet CA, and the CO2Z inlet to outlet CZ. Inlets VA and VZ will be closed off. The same applies when pressure is admitted to the CO2Z inlet
- Control of the CO2 inlets by OPEN/CLOSE combination release valves e.g. RTC-HA-HZ, see non-automatic release), of inlets VA / VZ e.g. by hand lever valve HH5/2 (see hand lever valves)
- Control pressure for CO2 inlets min. 4bar
- Maximum operating pressure 60bar
- Ambient temperature range: -25°C to +110°C
- Nominal bore (free cross section) of valve 4mm
- For pipe connection of the valve, 6 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.
