• Proven control reliable technology with integrated
soft start
• Soft start application of air to the system when
energized; can be adjusted for slower or faster buildup
of system pressure
• Rapid exhaust of downstream air when de-energized
to remove stored energy and allow safe access
• Memory, monitoring, and air flow control functions are
integrated into two identical valve elements. Valves
lock-out if asynchronous movement of valve elements
occurs during actuation or de-actuation, resulting in a
residual outlet pressure of less than 1% of supply.
P33T Schematic
• Reset can only be accomplished by the integrated
electrical (solenoid) reset. Cannot be reset by removing
Pressure and re-applying supply pressure.

wear compensating poppet design for quick response
and high flow capacity.
• LED indicators of main solenoid operation, reset
solenoid operation, and status indicator condition.
• Optional transducer for monitoring of downstream
pressure in the system.
• Dual exhaust silencers included.
• Not for use with clutch / brake applications.
• For use in conjunction with a safety relay or
