CAT 4 Double Redundant Safety Exhaust Valves

Parker Hannifin launched the P33T - CAT 4 redundant safety exhaust valves to the Global FRL series, this critical component used in conjunction with a safety relay or safety PLC for pneumatic circuits, offers Category 4 Performance Level e (PLe) in accordance with the latest Machine Directive EN ISO 13849-1.

Functionally the device's memory constantly monitors air flow control via two identical integrated valve elements. Valve lock-out is activated if asynchronous movement between the valve elements is detected during actuation or de-actuation, resulting in a residual outlet pressure of less than 1% of supply. As an additional safety feature, reset can only be accomplished by energizing the integrated electrical lock out solenoid - meaning it cannot be reset by simply removing and re-applying supply pressure.

Based on control-reliable technology, the IP65 rated P33T 3/2 normally closed valve offers integrated soft start functionality. As a result, air can be introduced in a controlled manner to the system when energised, thus allowing users to adjust for slower or faster build-up of system pressure. Importantly, the valve allows the rapid exhaust of downstream air when de-energised to remove stored energy and allow safe access.

Additional standard features of the P33T - CAT 4 Valve include LED status indicators of main and reset solenoid operation. Connection via a standard M12 (5-pin) socket provides control signal and feedback. An optional transducer for monitoring downstream system pressure is available.
