Parker’s P33 family of safety exhaust valves are perfect when applications demand a safe environment. These 3/2 normally closed valves are designed to rapidly exhaust compressed air in the event of a fault condition and to provide monitored coverage ensuring safe function. The valve is suitable for use up to Category 4, performance level e. Monitoring is achieved externally via a two channel system connected to a safety interface device.
