DM2C Series Double Valve DM2CNB21B22
- Redundant control can achieve Category 4, PL e, when used with proper safety controls
- Dynamic Monitoring, and air flow control functions are simply integrated into two identical valve elements
- Asynchronous movement of valve elements is detected by the dynamic monitoring and the valve latches in the safe condition, resulting in a residual outlet pressure of less than 1% of supply
- Manual valve reset
- Poppet design that is dirt tolerant, wear compensating for quick response and high flow capacity
- PTFE backup piston rings enhances valve endurance enabling operation with or without in-line lubrication
- 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
- High flow, clog resistant silencer included
- Base mounted for ease of valve replacement, captive valve-to-base mounting screws
- Inlet and outlet ports on both sides (plugs for unused ports included)
- SISTEMA Library available for download
