Pneumatic safety exhaust valve

Parker Hannifin propones a new safety exhaust valve, that rapidly exhausts compressed air in the event of a fault condition or when a machine has an emergency stop. The P33 is designed for two-channel control architectures and is externally monitored. It has a patented fail-safe design, and is suitable for use in applications up to category 4 performance level e.
The valve is available with adjustable soft-start and high flow exhaust performance to ensure rapid exhaust of compressed air when required. Designing a control system with a high diagnostic coverage provides a high means of fault detection within the valve, while LEDs provide operators with a clear status indication of sensor power, main solenoid operation and fault condition.
The design has been optimised for long service life (B10d), very high flow rates, high faulted flow rates, compact design and high mean time to failure (MTTF) values. Connectivity is via two M12 connectors that provide solenoid and pressure sensor interfacing. The fail-safe design of the P33 family is maintenance-free and requires no additional silencers or mufflers.
