Product Introduction
The Hongsen 3/8" Normally Open Defrost Solenoid Valve is a precision-engineered control component specifically designed for hot gas defrost systems in commercial refrigeration, cold chain logistics, and transport cooling units. It reliably controls the flow of high-temperature hot gas into the evaporator to melt ice buildup, ensuring optimal cooling performance and energy efficiency.
Built by Hongsen (HONGSEN), a leading manufacturer in China's refrigeration components industry, this valve features a durable forged brass body, high-precision armature assembly, and an IP65 rated coil for maximum durability in harsh environments. It is widely used in cold storage rooms, walk-in freezers, refrigerated trucks (e.g., Thermo King, Carrier), supermarket display cases, and air conditioning systems.
Key Features & Advantages
Normally Open (NO) Design for Defrost
Valve remains open when de-energized (ensuring system safety during power failure) and closes when energized. Ideal for hot gas defrost circuits where continuous refrigerant flow is required during defrost mode.
High Pressure & Temperature Resistance
Maximum working pressure up to 45 Bar, supporting medium temperatures from -30°C to +105°C. Perfect for hot gas defrost lines (high temp) and low-temperature suction lines (low temp).
Wide Compatibility
Works with all major HCFC/HFC refrigerants including R22, R134a, R404A, R410A, R507A, R407C, etc.
IP65 Waterproof & Dustproof
Equipped with an IP65 rated coil and standard junction box, resistant to moisture, dust, and extreme weather. Suitable for outdoor installation on refrigerated trucks and cold storage units.
3/8" Standard Interface
3/8 inch (9.525mm) male thread connection, compatible with standard refrigeration pipelines. Easy to install and replace.
Multiple Voltage Options
Standard DC24V for vehicle-mounted systems; customizable to DC12V, AC110V, 220V, 380V to meet global power supply needs.
Easy Maintenance
Screw-on coil design allows quick replacement without removing the valve body, reducing downtime during repairs.
