The new Ross DM2 series pneumatic safety valves have dual valve elements for redundancy. They also incorporate built in dynamic monitoring and dynamic memory for full compliance with category 4 safety systems. (per AS 4024.1)
Flow paths through the valve use the Crossflow SERPAR technology developed by Ross Controls for power stamping press applications. Design improvements allow better monitoring for diminished performance and fault memory to preclude accidental reset.
The memory monitoring and air-flow control functions are all integrated into the valves’ two identical operating elements. The poppet-based internals ensure fast repeatable response, high flow rates and reliable service.
Air can be lube or non-lube. The Ross DM2 series is a base mounted valve with versatile double porting making pipe work and maintenance simple. An optional status indicator allows easy integration with electrical controls.
