Ross Controls offers RSe safety exhaust and safe cylinder return double valves

Feb. 27, 2018 – Ross Controls has introduced its RSe series sub-base mounted valves for safety exhaust (dump) and safe cylinder return applications up to Category-4 PLe.

The series’ safety function will supply compressed air to a machine/system until signalled to shut off and exhaust any pneumatics energy from downstream of the valve, thus reducing the hazards associated with the presence of residual pneumatics energy during employee access and/or production-related minor servicing, says the company.

As well, the safety function is able to control the direction of air flow into and out of a double-acting cylinder or other pneumatic actuator for normal operation, and according to Ross Controls, will return the cylinder/actuator to its home “safe” position whenever a fault occurs within the valve.

The new RSe Series control-reliable double valves are redundant valves designed for external monitoring to meet the needs and requirements of safe air supply/exhaust (3/2 Valves) and safe cylinder return (5/2 Valves) applications for machinery with pneumatic controls, adds Ross. The RSe Series valves have an overall function of a single solenoid pilot-­operated, spring return valve, and incorporate a spool design for rapid response. Two PNP proximity sensors are included, one for each valve, to be monitored with an external monitoring system.
