Solenoid valve Applicability: NA equal to spend money on waste, but also trouble!

1 medium characteristics
1.1 The quality of gas, liquid or mixed states were selected different varieties of solenoid valves, cases ZQDF for air the ZQDF-Y for liquid ZQDF-2 (-3) for steam, otherwise easily lead to malfunction. ZDF series of multi-function solenoid valve the can altogether in the air. Liquid. Best when the state media to install the user will not have tuning.
1.2 medium temperature products with different specifications, otherwise the coil will burn, seals aging, seriously affecting the life of life.
1.3 medium viscosity, usually in 50cSt. If this value is exceeded, greater than 15mm diameter with a the ZDF series of multi-function solenoid valve for special order. Diameter less than 15mm high viscosity valve.
1.4 media cleanliness is not high before the solenoid valve should be equipped with recoil filter valve, low pressure fashion can be used direct action diaphragm solenoid valve.
1.5 If the media directional flow, are not allowed back the ZDF-N ZQDF-N single need to use two-way flow, please make a special request.
1.6 The medium temperature should be selected in the solenoid valve within the allowable range.standard air cylinder
2 pipe parameters
2.1 under medium flow pipe connection requirements and select the valve diameter and model.
2.2 In accordance with the flow and valve Kv value of the selected nominal diameter, also optional with pipe diameter.
2.3 Working pressure
Minimum working pressure 0.04Mpa indirect Pilot is optional; minimum working pressure is close to or less than zero must use direct action or step-by-step direct.direct acting solenoid valves
