New modular, key-operated interlocks for pneumatic valves

Fortress Interlocks Ltdvisit website

 

Fortress has redeveloped its Pneumatic Valve+ (PV+) unit into a modular design that enables arrays of valves, trapped key interlocks and key switches to be configured in any combination.

The PV+ is suitable for isolating pneumatic power sources and is conventionally key-free, but the revised modular design enables the unit to be used in conjunction with other functional modules, giving users greater flexibility.

PV+ units complement the Fortress mGard range of mechanical key interlocks for heavy-duty applications; these 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. Because 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.
