DM2C Series Double Valve DM2CNA54A21
Description
• 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
