Without control air, the valve is closed and the grit flow is shut off.  The valve uses a spring to depress the plunger and compress the rubber washer, providing complete shut-off of grit and air from the pot when there is no air pressure applied to the valve’s control air input.
 

A pressure regulator (usually mounted to the main control box), allows the user to adjust the grit flow by adjusting the air pressure. A fully functioning S4C valve system includes a separate actuated air valve and a special dual function deadman switch to allow a “blowdown” feature.  This allows the operator to instantly switch from blasting (grit and air) to “blowdown” (air only).

 

Conversion kits are available to change vessels from old style pinch valves and metering valves to the safer and more efficient S4C valves.  Call for information.
