Power isolation – Pneumatic Valve+ unit

Fortress has redeveloped its Pneumatic Valve+ (PV+) unit into a modular design, which, the company says, allows the configuration of an array of valves, trapped key interlocks and key switches in any combination.

The PV+ is described as suitable for the isolation of a pneumatic power source and is conventionally key-free. However, the revised modular design allows the unit to be used in conjunction with other functional modules, giving the user flexibility.

The PV+ has been designed to complement the Fortress mGard range of mechanical key interlocks for heavy applications. With the new PV+, a combination of isolation/access keys is possible, with sequential or non-sequential key operation available, says Fortress. The PV+ has been designed with a zinc-alloy valve body and mild-steel zinc-coated plates.
