Fortress launches its latest modular pneumatic valve interlocks

Fortress has unleashed its redeveloped pneumatic valve interlock range.

The units feature a modular design that allows the configuration of an array of valves, trapped key interlocks and key switches in any combination.

The pneumatic valves (PV+) are suitable for the isolation of a pneumatic power sources and are key free, but can also allow the unit to be used in conjunction with other functional modules. 

The PV+ 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 new PV+, a combination of isolation/access keys is possible, with sequential or non-sequential key operation available.

The PV+ has been designed with a zinc alloy valve body and mild steel zinc coated plates.
