This VdS approved sequence valve is designed for the pressure-dependent control of one SHEVS cylinder with pressurising valve for supplying air to the cylinder while following idle.
In normal position (pressure below 7 bar), the CA outlet has exhausted, allowing the SHEVS cylinder to be pulled along by a ventilation actuator. When the CO2 inlet is charged with a pressure of more than 10 bar, the valve reverses, connecting the CO2 inlet to the CA outlet. After a system exhaust, the valve will automatically reset.
For pipe connection of the valve, two male connectors 1/8″ (e.g. B1-6-1/8) will be required additionally.
The design of the SHEVS may require reliable venting of the piping.
