SMC VHS40-N04A-Z VHS series mechanical valve isolates supplied pressure and exhausts downstream air for maintenance. NPT 1/2 in. port, lockable in exhaust position. Part of an energy isolation system.

The VHS series provides a convenient means of isolating supplied pressure in a pneumatic system and exhausting downstream pressure for maintenance purposes. The units can be locked in the exhaust position and can be an integral part of an energy isolation system. Air flow direction is easily identified by handle orientation and labelling. They can be used alone or can be conveniently connected to an FRL assembly using modular spacers.
