Control Reliable Double Valves
with Dynamic Monitoring & Memory
This valve is not designed for controlling clutch/brake mechanisms on mechanical power presses,
see DM2

Dynamic Monitoring With Complete Memory:
Memory, monitoring, and air flow control functions are
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
– cannot be reset by removing and re-applying supply pressure. Reset
can only be accomplished by the optional integrated electrical (solenoid) reset.
Basic 3/2 Normally Closed Valve Function:
Dirt tolerant, wear compensating poppet design for quick
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.
