Schmidt Combo Valve™

The ComboValve is normally closed, self sealing, fail-safe valve that combines the functions of the air inlet valve and blowdown valve, eliminating premature failure of the blowdown system. It is controlled with either pneumatic or electric remote controls. When the deadman control is pressed, the valve’s unitized piston assembly instantly shifts, opening the air inlet and pinching the blowdown hose closed, starting the blasting operation. None of the usual wear or failures found in other blowdown systems can occur with a ComboValve.

The ComboValve also eliminates the need for abrasive traps, expensive plungers and diaphragms     that can require frequent, unscheduled and costly downtime. An inexpensive blowdown hose can be replaced in just a few minutes, and any service or repair can be safely performed without removing the valve. In certain applications, its unique design can eliminate potential safety hazards from the operation are by simply extending the blowdown hose out of harms way. The ComboValve operates on 50 to 150 psi air pressure and retrofits to most brands of blasting equipment. A large internal air passage eliminates pressure loss common to other systems
