General
FDF solenoid valve is used for fluoride liquid pipe, suction pipe, hot steam pipe, and can be widely used in refrigeration, freezing, air conditioning equipment.
Characteristics
- Solenoid valves can be divided into direct-acting and pilot-type (servo) configurations.
- Can be normally closed (NC) and normally open (NO).
- There are many AC voltage and DC voltage coils to choose from.
- Pilot type (main valve port ≥ 5mm) working pressure difference range:
- Communication: 0.05-21bar
- DC: 0.05-17 bar
- Operating pressure difference range of direct-acting (valve ≤ 3mm):
- Communication: 0-21bar
DC:0-17bar
- Maximum working pressure: 30bar.
- Use working fluid temperature: -25°C～105°C.
- FDF25M and above solenoid valves are also available in flange mounting styles.
- UL/CUL certification available.
Other Technical Data
Note: The model number is followed by "E" for manual lever, "F" for method flange, "A" for lumbar flange, "J" for improved, and "B" for threaded connection, with ";K" Normally open solenoid valve.
Note: For other operating characteristics and specifications, please contact the company.
The value of Kv is the water flow rate when the valve passes ρ=1000kg/m3 and the pressure drop is 1bar before and after
Nominal Liquid Capacity(KW)
Rated liquid and suction vapour capacity is based on evaporating temperature te=4.4℃,liquid temperature ahead of valve t1=38℃,and pressure drop in valve R134a △P=0.15 bar, R22、R404A、R507、R407c、R410A ΔP=0.21bar.
Rated hot gas capacity is based on condensing temperature tc=+40℃,pressure drop across valveΔP=0.8bar,hot gas temperature th=+65℃,and subcooling of refrigerant Δtsub=4K.
