Valvula cartucho

Catalog 3105/USA

Technical Information General Description
The DPR083C Series Valve is a normally closed valves used for reducing inlet pressure to 6.9-20.7 Bar (100-300 PSI) (depending on model and coil wattage). A common application of this valve is as a transmission-shifter valve where a fixed regulated pressure is required regardless of inlet pressure.

Operation
With the solenoid coil de-energized, the spool is held in a closed position by spring force. In this mode, the regulated pressure port is open to tank and the pressure inlet port is blocked. As a voltage signal is applied to the solenoid coil, the spool will begin to travel to a position where the pressure inlet port is connected to the regulated pressure port. At this point, reduced pressure becomes a function of the voltage signal. As long as the voltage signal is constant, the reduced pressure at the regulated pressure port will remain fixed regardless of any changes in inlet flow or inlet pressure. As the voltage signal increases or decreases, the reduced pressure at the regulated pressure port will change with respect to the change in the voltage signal. Once a full voltage signal is given, the reduced pressure of the regulated pressure port will be at the maximum reduced pressure for that valve (i.e. 6.9 Bar (100 PSI) on Model DPR083C2 with 30 watt coil and 13.8 Bar (200 PSI) on Model DPR083C5 with a 17 watt coil).
