AQV-PPH Single Operator, Pressure Hold Remote Control System

This Auto Quantum Valve (AQV)-Pneumatic Pressure Hold (PPH) is a remote-control system for a single operator. With this single operator system, the blast pot will depressurize when the operator depressurizes the hose.

With this setup, the blast pot will remain pressurized when the handle is released and cuts off abrasive flow.
