The 5/2 RSe Series valve is designed to control the direction of air flow into and out of a double-acting cylinder or other pneumatic actuator in order to drive the cylinder forward or backward to suit the requirements of the machine operation. However, the RSe Series does this with the same level of control expected of the machine’s/system’s safety circuit. The safety function of the RSe Series valve is to return the cylinder/actuator to its home “safe” position whenever a fault occurs within the valve. Such a monitoring system must be capable of inhibiting the operation of the valve.

The RSe Series valves are designed for external monitoring for safe, redundant operation of the valves. The RSe Series valves are constructed of redundant, spool type valves, and have an overall function of a single solenoid pilot-operated, spring return valve. Each single valve in the RSe Series is equipped with a PNP proximity sensor. Monitoring both of these sensors on each actuation and de-actuation of the RSe Series valve provides a diagnostic coverage of 99%. Monitoring of these sensors is to be done by an external monitoring system.
