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.
