Ross Controls DM1 Series C Operation Instructions Manual

Control Reliable Double Valves
with Dynamic Monitoring
Dynamic Monitoring: Monitoring and air flow control functions are integrated into two identical valve
elements for CAT 4 applications. The valve exhausts downstream air if asynchronous movement of
valve elements occurs during actuation or de-actuation, resulting in a residual outlet pressure of less
than 1% of supply. If the abnormality clears itself, the valve will return to the ready-to-run state; there
is no memory of the abnormal behavior, as in the ROSS DM
that require an intentional reset following lockout.
Basic 3/2 Normally Closed Valve Function:
quick response and high flow capacity. PTFE back-up rings on pistons to enhance valve endurance –
operates with or without inline lubrication.
Ready-to-run:
If an abnormality clears itself upon the removal of electricity to both solenoids, it will be
ready-to-run again. It does not remember the abnormality and stay in a locked-out state until intentionally
reset. Therefore, cumulative abnormalities may go undetected.
Status Indicator: Includes a pressure switch with both normally open (NO) and normally closed (NC)
contacts to provide status feedback to the control system indicating whether the valve is in the "ready-
to-run" condition or has experienced abnormal function. MUST be integrated into machine controls in
order to prevent run signal until fault is cleared in valve. This indicator only reports status, it is not part
of a lockout function.
Silencers: All models include high flow, clog resistant silencers.
Mounting: Base mounted – with BSPP or NPT pipe threads. Inlet and outlet ports on both sides
provide for flexible piping (plugs for unused ports included). Captive valve-to-base mounting screws.
