DM2 Series C Safe Exhaust Valve, Explosion Proof DM2CDA88A21019
- 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
- Reset can only be accomplished by the integrated electrical (solenoid) reset; the valve cannot be reset by removing and re-applying supply pressure
- Poppet design that is dirt tolerant, wear compensating for quick response and high flow capacity
- Explosion-proof Coils contain any spark originating from within the coil or housing preventing the ignition of any flammable material in the surrounding environment, resulting in a larger explosion
- 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
- Inlet and outlet ports on both sides provide for flexible piping (plugs for unused ports included)
