ADF type ammonia solenoid valve is an automatic control valve operated by alternating current AC 220V or direct current DC 24V power. This series of valves is specifically designed for automatic control in refrigeration devices and automation systems using ammonia or Freon as the medium. It directly controls the flow and shutoff of the medium in the pipeline. This series of valves includes models ADF 20 and ADF 25F and ADF 25FJ. The nominal diameter covers DN20 to DN25. It has the capacity to work stably within a wide temperature range of minus 35 to 150 degrees Celsius and a pressure range of 0.03 to 2.0 MPa. It is an ideal choice for the automatic control of modern refrigeration systems.

Material is excellent and durable. The valve body and main components are all made of high quality stainless steel. It has strong corrosion resistance and excellent pressure and impact resistance. This effectively extends the service life of the product.

Low pressure difference quick opening. The valve adopts a lightweight diaphragm sealing structure. Due to the light weight of the overall structure it can open smoothly under a very small pipeline pressure difference as low as 0.03 MPa.

Moisture proof and anti erosion electromagnetic coil. The excitation coil adopts a professional moisture proof design and utilizes a cold bonded sealing moisture proof structure. This design effectively isolates external moisture and the erosion of medium gas around the pipeline. It fundamentally eliminates the hidden danger of coil burnout caused by moisture.

Tight sealing and superior temperature resistance. The core diaphragm sealing material is selected from imported polytetrafluoroethylene PTFE reinforced composite material. It not only has excellent sealing performance to eliminate medium leakage but also possesses both high temperature and severe cold resistance characteristics. It still performs stably under complex working conditions.
