The SMC VHS40-04 residual pressure release valve exhausts trapped air from pneumatic lines to allow safe maintenance on downstream equipment. This 3-port manual valve features 1/2-inch Rc ports and a rotary handle that shifts between supply and exhaust positions without requiring electrical power. It handles up to 1.0 MPa operating pressure and installs directly in compressed-air circuits on machinery where lockout of residual pressure is required.
