ROSS
CONTROLS® is proud to introduce its new line of DM2®D
Crossflow™ SERPAR® Double Valves with TOTAL Dynamic
Monitoring & Memory for Press Clutch/Brake Applications.
ROSS’
new DM2®D Crossflow™ SERPAR® Double
Valves combine the tough, dirt tolerant, wear compensating characteristics
of poppet technology with new double valve features in response to the
changing demands of the mechanical press industry and its associated
standards and regulations regarding pneumatically controlled clutch/brake
applications. The consensus standards and best practice require that,
in case of a failure within the valve, the clutch and brake mechanisms
be quickly exhausted, a monitor takes action to prevent further operation,
and a method to alert personnel is incorporated. These new features
also make the DM2®D valve suitable for use in other
Category-3 & -4 safety-related applications.
Memory,
monitoring, and air-flow control functions are simply integrated into
two identical valve elements. DM2®D valves lock out
due to asynchronous movement of valve elements during actuation or de-actuation,
resulting in a residual outlet pressure of less than 1% of supply. Overt
action is required for reset, and reset can only be accomplished by
applying a remote air signal or by energizing the optional integrated
electrical (solenoid) reset.
The
DM2®D valves are base mounted, and available with BSPP
or NPT pipe threads. Inlet and outlet ports on both sides of the bases
provide for flexibility in piping. These new DM2®D Valves
are available in 4 sizes, providing a broad range of flow capabilities
to meet your needs. Valves are designated by the nominal sizes 4, 8,
12, and 30 with outlet ports up to 2”.
An
optional Status Indicator includes a pressure switch with both normally
open and normally closed contacts to provide status feedback to the
press control system indicating whether the valve is in the lock-out
or ready-to-run condition. Also, all models include a high flow, clog
resistant silencer.
