U.S. Solid 1/4″ Brass Electric Solenoid Valve
The U.S. Solid valve features a solid brass body designed for corrosion resistance and durability in higher temperature environments. It uses a Viton gasket to resist chemicals common in refrigeration fluids and oils, promoting long service life. The valve is direct-acting and responds rapidly, typically opening or closing within a second when energized or de-energized. It is suitable for high-temperature fluids and non-potable liquids; however, it should not be used with drinking water. With a life cycle projection in the millions of operations under proper conditions, this valve is built to handle frequent cycling in refrigeration lines.
- Brass construction with corrosion resistance
- Viton seal for high-temperature and chemical resistance
- Fast actuation (<1 second)
- Long life cycle (over a million cycles)
Baerkian Upgraded Refrigerator Water Inlet Valve
This dual-solenoid valve is designed as a direct replacement for models using part number 242252702, commonly found in Frigidaire and Kenmore refrigerators. It combines ice maker and water dispenser valve functions into a single unit, simplifying installation and maintenance. The included mounting bracket and quick-connect fittings streamline replacement in compatible units. The dual-solenoid design supports simultaneous control of ice-making and water dispensing, offering reliability in cold-storage appliances where precise water control is critical.
- Direct replacement for specified Frigidaire/Kenmore models
- Dual solenoid design for ice maker and dispenser
- Includes mounting bracket and quick-connect fittings
SNS 1/4″ NPT DC12V Brass Solenoid Valve
The SNS valve offers a compact 1/4″ NPT brass body with DC12V operation, making it suitable for refrigeration lines requiring tight control of water or other compatible fluids. It is a two-way, normally closed valve designed to seal when de-energized, ensuring no accidental leakage in coolers or ice makers. Its operating range from sub-freezing to modest temperatures makes it adaptable for standard refrigeration cycles. It is compatible with water, air, or oil in many HVAC applications, expanding its use beyond just drinking water lines.
- Brass body; 1/4″ NPT fittings
- DC12V operation; normally closed
- Versatile for water, air, or oil
Beduan 12V 1/4″ Inlet Water Valve
Beduan’s 12V inlet valve combines a metal and plastic construction with a compact 1/4″ tubing interface, making it a practical option for refrigeration lines requiring reliable valve operation in colder environments. The 12V DC operation aligns well with many standard refrigerator and RO systems. The mix of materials aims to balance durability with cost effectiveness, suitable for typical household or light commercial installations where a robust solenoid is needed without excessive bulk.
- 12V DC operation
- 1/4″ tubing connection
- Metal and plastic construction
APPLI PARTS APVI-1111 120V Inlet Valve
This APVI-1111 valve operates at 120V and offers an inlet connection of 3/4″ NPT with a 1/4″ outlet, making it suitable for standard refrigerator and ice maker feeds. It is designed to electrically control water flow to fill trays or dispensers as dictated by the fridge’s control system. The 110–120V compatibility enables use in many built-in or standalone refrigeration units. The valve’s universal input compatibility allows substitution across brands when power requirements are identical.
- 120V AC operation; 3/4″ NPT inlet
- 1/4″ outlet; compatible with many brands
- Simple integration for ice maker/water systems
Buying Guide
Key considerations when selecting a liquid solenoid valve for refrigeration include fluid compatibility, voltage, and connection sizing. For drinking water lines, avoid brass valves without potable-water certification and consider lead-free options where applicable. Dual-solenoid designs can simplify installations by consolidating valve control for ice makers and dispensers, but ensure the unit’s electrical specifications match the appliance’s supply. Durability features such as Viton seals and brass bodies improve chemical and temperature resistance, while fast response times help prevent overfilling or leaks in cooling cycles. Installation ease is aided by included mounting hardware and standard NPT or quick-connect fittings. Compare valve size (1/4″ vs 3/4″ NPT), voltage (12V DC vs 120V AC), and whether the unit is normally closed or normally open to fit your refrigeration system’s control logic. Durability and cleaning access are important in systems where debris could enter solenoid cavities. For retrofits, verify model compatibility with your refrigerator’s model number, as some units are designed as direct replacements for specific brands.
Performance perspective: 12V DC valves are common in consumer refrigeration and offer compact form factors with rapid actuation, ideal for tight spaces. 110V AC units suit larger installations or professional equipment where standard appliance power is available. Dual-solenoid water inlet valves provide integrated control but require sufficient electrical supply and space for installation. Material choice matters: metal bodies resist impact and corrosion but may be heavier; plastic components can reduce weight and cost but may have lower heat resistance. Reliability and longevity depend on proper operating conditions, including correct voltage, pressure, and fluid type. When possible, review valve lifecycle data and ensure maintenance plans address gasket replacement and occasional cleaning to prevent clogging in cold environments.
