Fortress Pneumatic Valve+ (PV+)

The Pneumatic Valve+ (PV+) unit’s modular design allows the configuration of an array of valves, trapped key interlocks and key switches in any combination.

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

The unit has been designed to complement the Fortress mGard range of mechanical key interlocks for heavy applications, which work by releasing and trapping keys in a predetermined sequence to ensure safe operation of dangerous machinery; access is not permitted until a safe condition has been achieved.

With the unit, a combination of isolation/access keys is possible, with sequential or non-sequential key operation available. As mGard is designed to be modular, it is possible to add modules to create unique configurations. The PV+ has been designed with a zinc alloy valve body and mild steel zinc-coated plates.
