The R3710 Series restrictors limit pressure and flow direction in pneumatic systems.

The R-3714 diode tee provides through line low volume exhaust whenever the pressure to the diode branch is at a lower value than pressure on the through line. A higher pressure at the diode branch closes the diode and allows normal operation in the through line. Air can flow out of the bottom of the tee causing a slight reverse flow. The R-3714 is not designed for systems where the reverse flow through the restrictor can be trapped between a shut off device and an actuator.
