GDF series compact solenoid valveDetailed product description：

GDF series compact solenoid valve

GDF solenoid valve is a compact solenoid valve used in the liquid, suction, and hot steam pipelines of refrigeration, refrigeration, and air conditioning systems that use fluoride refrigerants.
Detailed introduction
characteristic
GDF type solenoid valve is a servo type solenoid valve, suitable for liquid pipelines, suction pipelines, and hot steam pipelines of fluoride refrigerants.
Electromagnetic valves are suitable for refrigeration, freezing, and air conditioning units.
There are various AC and DC voltage coils to choose from.
Suitable for HCFCs, HFC refrigerants (excluding R717) and compatible lubricating oils.
The applicable working fluid temperature is -40 ℃ to+105 ℃, and the highest temperature during defrosting is+130 ℃.
Applicable ambient temperature range: -40 ℃ to+55 ℃.
The maximum working pressure is 45 bar.
Hydraulic resistance strength ≥ 68bar.
UL/CUL certification is available.

Kv value: The flow rate, unit m3/h, and density ρ=1000 kg/m3 of water passing through an electromagnetic valve with a pressure difference of 1 bar

The nominal cooling capacity of liquid and suction is: The nominal cooling capacity of hot gas operating conditions are:
Evaporation temperature te=4.4 ℃ Condensation temperature tc=+40 ℃
The liquid temperature in front of the valve is t1=38 ℃, and the pressure drop across the valve is Δ P=0.8bar
By reducing the pressure of R134a Δ P=0.15bar through the solenoid valve, the temperature of the hot steam th=+65 ℃
R22, R404A, R507, R407c Δ P=0.21bar liquid refrigerant subcooling degree
