DGPV-2 are used in suction lines for the opening against high differential pressure, e.g. after hot gas defrost in large industrial refrigeration systems with ammonia, fluorinated refrigerants or CO2 . The DGPV-2 valve is factory configured to open in 2 steps. By following a simple procedure the valve can be configured to open in 1 step only. In 2-step configuration, step 1 opens to approx. 10% of the capacity after the pilot solenoid valves are energized. Step 2 opens after Step 1 has opened for a certain amount of time (20 sec minimum, adjustable).
