SMC VHS20-01B is a 3-port manual valve that shuts off the air supply and exhausts residual pressure in pneumatic circuits. The 1/8-inch ports connect in line with standard tubing or fittings, and the lever handle rotates to the shut position to block inlet flow while venting the outlet side to atmosphere. This configuration supports safe maintenance on downstream components without requiring separate bleed valves or additional plumbing.
