Ross Controls DM2C Series Manual

Control Reliable Double Valves
with Dynamic Monitoring & Memory
Basic Size 2, 4, 8, 12 and 30

Dynamic Monitoring With Complete Memory:

simply integrated into two identical valve elements. 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.
An Action is Required for Reset
can only be accomplished by the optional integrated electrical (solenoid) reset.

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.
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.

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.
Basic Size 12 and 30

Intermediate Pilots:

Increases pilot air flow for fast valve response, making it possible to use the same size
solenoids as valve sizes 2, 4 & 8, thereby reducing electrical power requirements for these larger valves.

Flow Media: Filtered, lubricated or unlubricated (mineral oils according
to DIN 51519, viscosity classes 32-46).
Inlet Pressure: Basic Size 2: 45 to 150 psig (3.1 to 10.3 bar).
Pressure Switch (Status Indicator) Rating: Contacts - 5 amps at 250
