Ross Controls has announced the introduction of the new compact size 2 DM2 Series D valve, the latest addition to the company’s press application double-valve family.

This 100 per cent dynamically-monitored valve has complete memory, is control-reliable and category-4 rated for press clutch/brake applications.

“Now, customers can reap the superior safety benefits of Ross’ DM2 Series D products in a new, smaller design.” Ross said about the new product.

“For exceptional convenience and value, the DM2 Series D products integrate memory, monitoring and air flow functions into two identical valve elements. In the event of asynchronous valve element movement during actuation or de-actuation, the DM2 Series D valves will lock out, resulting in less than 1 per cent residual outlet pressure, inhibiting further operation of the press.”

For enhanced safety, DM2 Series D valves were designed so that removing and reapplying air pressure cannot reset the valve. A variety of fault reset options are provided (remote air signal, optional integrated electrical/solenoid, or manual), all of which require overt action per Ansi, EN and many other global regulations.

As with the rest of the DM2 Series D family, the size 2 valve offers Ross’s’ patented dirt-tolerant, wear-compensating poppet design which provides quick response and high flow capacity. To ensure long service life and sure shifting capability in potentially harsh environments, the valve has teflon-coated back-up rings on its pistons (non-lube service standard, inline lubrication acceptable).

The DM2 Series D size 2 valve is base-mounted and available with BSPP or NPT pipe threads.

Inlet and outlet ports
For greater flexibility in piping, the valve was designed with inlet and outlet ports on both sides (plugs included for unused ports). The size 2 valve offers a 3/2 normally-closed valve function and is available in 1/4 or 3/8 inch port sizes.

The Ross DM2 Series D size 2 double valve is suitable for the following applications: small gap frame presses; small die cut presses, cylinder presses, small shears and any small control-reliable pneumatic application.

All of the DM2 Series D standard valves include a high-flow, clog resistant silencer for noise abatement. An optional status indicator pressure switch is also available, which can be initially installed or added in the field. The pressure switch has both normally-open and normally-closed contacts and provides status feedback (lock-out or ready-to-run condition) to the press control system.
