Product Overview of Ammonia Solenoid Valves

Ammonia solenoid valves are AC-powered automatic valves, mainly used for pipeline control of refrigeration systems with ammonia or Freon as the medium. With an operating pressure range of 0.03~6.4MPa and an applicable temperature range of -196℃ to 150℃, they are widely applied in industries such as urban construction, chemical industry, metallurgy, petroleum, and pharmaceuticals.

Key Features of Ammonia Solenoid Valves

The main body is made of high-quality stainless steel, adopting a diaphragm seal structure design to achieve low pressure difference startup (0.03MPa).

Available connection methods include steel union connection, flanged welding, etc.

The excitation coil adopts a cold-bonded sealed moisture-proof structure to prevent medium erosion.

The sealing diaphragm is made of imported PTFE-reinforced composite material.

Supports multiple rated voltages: AC 380/220/110/36V and DC 220/110/36/24V.
