3217 Compensating Self Relieving Air Pressure Regulating Valve

The 3217 compensating self relieving valve is a mechanically actuated, sub-plate mounted valve. It is both compensating and self-relieving with an adjustable spring for setting the valve working pressure range. Movement of the spool stem into the valve produces a proportional output pressure, within the working range of the valve.


  • Used anywhere where an accurate air pressure is required
  • Used mainly in Kobelt pressure control heads and dual function control heads for accurate control of throttle actuators, positioning actuators and air applied brakes.

A repair kit 3217-RK is available.
