Two-Step Solenoid Valve
DFHV
Description
Size: DN25 to DN80 ar
Max Operating Pressure: 6.3Mpa
Suitable medium: fluorine, ammonia and other refrigerants.
Operating temperature: -46°C～+150°C
The DFHV series is a 2 step solenoid valve opened by the pressure difference between the inlet and the outlet (pressure difference 0.2 Bar). The first step is opened to 20% of the flow rate and then the 2nd step will open to 100%. This series can be set up so that the second solenoid can independently open the valve to 100% ignoring step 1. This could run the risk of liquid shock.
