The SMC VHS40-04-XG is a 1/2-inch port lockout valve that shuts off the incoming air supply and exhausts downstream pressure in pneumatic circuits. Its sliding handle moves to the closed position where a padlock can be applied, preventing accidental re-energization during maintenance or repair work on equipment. Rated for use in compressed-air systems, the valve is mounted inline and complies with standard lockout/tagout requirements for industrial machinery.
