The KAK FDF2A normally closed solenoid valve is a compact, small-flow, hard-sealed valve designed for precise refrigerant control in refrigeration, air conditioning, dehumidification and ice-making equipment. It remains closed when de-energized to ensure safety and prevent reverse flow, and it is compatible with common refrigerants such as R22, R407C, R134a and R410A.
Key Features
- Normally closed structure – safe when power is off
- Compact brass body with copper tube connections (OD 6.0 mm)
- Compatible with R22 / R407C / R134a / R410A
- Low power consumption, long service life (> 3 million cycles)
- Coil voltage options: AC230V, AC220V, AC110V, DC24V (50/60Hz)
- Working pressure 3.0–4.2 MPa, max. operating pressure 2.6 MPa
- Environmental temperature: -20°C ~ +55°C
- Insulation class: Class B
- Coil wire length and terminal type can be customized upon request
Applications
This solenoid valve is suitable for small-capacity and Japanese-style refrigeration/HVAC systems, including:
- Refrigerators & freezers
- Room air conditioners and dehumidifiers
- Ice makers and vending machines
- Refrigerant switching / on-off control circuits
