The Applied Tandem Air Control Valve is a rugged, cast iron, pilot operated, spring return diaphragm type valve, designed for use with blast pot remote control systems. Located in the air pusher line, the tandem valve is used to turn the blasting compressed air supply on and off as required.

When combined with the Applied Corse Abrasive Valve, the tandem valve allows the blast pot to feature an air blow down system where the abrasive flow is shut off and the compressed air supply is used to blow residual abrasive and dust from the blast cleaned component. The tandem valve is available in a variety of sizes.
