Ross M DM2 C Series Manual

Control Reliable Modular Double Valves
with Integrated Soft Start
Double Valves with Dynamic Monitoring & Memory
Dynamic Monitoring With Memory:
two identical valve elements. Valves lock-out if asynchronous movement of valve elements occurs during
actuation or de-actuation, resulting in a residual outlet pressure of less than 1% of supply.
An Action is Required for Reset:
can be accomplished by the integrated electrical (solenoid) reset or by the manual reset button.
Basic 3/2 Normally Closed Valve Function:
response and high flow capacity. PTFE back-up rings on pistons to enhance valve endurance – operates
with or without inline lubrication.
LED Indication: Light-emitting diode (LED) indicators of main solenoid operation, reset solenoid operation,
and status indicator condition.
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 lockout or
ready-to-run condition.
Transducer (optional):
Silencers:
All models include high flow, clog resistant silencers.

Inlet Pressure: 30 to 150 psig (2 to 10 bar). Under certain circumstances,
such as maximum restriction of the adjustable flow control or a very large
downstream system volume, the minimum inlet pressure may need to be
set up to 60 psig (4 bar) to prevent nuisance valve faults.
Pressure Switch (Status Indicator) Rating: 5 amps at 30 volts DC.
Monitoring: Dynamically, cyclically, internally during each actuating and
de-actuating movement. Monitoring function has memory and requires
an overt act to reset unit after lockout.
Mounting Orientation: Vertically with pilot solenoids on top.
