U.S. Solid 1/4″ NPT Brass Electric Solenoid Valve
This valve features a solid brass body designed for corrosion resistance and higher temperature applications. It uses a Viton gasket for chemical and heat resistance, making it suitable for fuels and non-potable fluids. The valve is direct-acting and responds in under one second when energized or de-energized, offering rapid shutoff and reliable flow control. With a life cycle projection exceeding one million cycles under proper conditions, it suits demanding refrigeration and industrial uses where durability matters.
Features: Brass construction; Viton seal; fast actuation; high-temperature tolerance; long cycle life.
Baerkian Refrigerator Water Inlet Valve (Dual Solenoid)
This direct replacement valve is designed for specific refrigerators, featuring dual solenoids to control both ice maker and water dispenser functions in one unit. It includes a mounting bracket and quick-connect fittings for straightforward installation. The product is tailored to fit the 242252702 part number family, enabling seamless upgrades or replacements in compatible Frigidaire and Kenmore models.
Features: Direct replacement; dual solenoid design; mounting hardware included; quick-connect fittings.
SNS 1/4″ NPT DC12V Brass Solenoid Valve
This two-way valve uses a brass body and operates at DC12V, suitable for water, air, or oil applications. It is designed for reliable normally closed operation with a broad working temperature range from -5°C to 85°C, making it appropriate for various refrigeration and HVAC tasks where quick shutoff is essential.
Features: 1/4″ NPT; normally closed; versatile for liquids and gases; wide operating temperature range.
Beduan 110V 1/4″ Inlet Water Solenoid Valve
Beduan’s 110V inlet valve supports standard RO and filtration setups, featuring a 1/4″ tube and metal/plastic construction. It is designed for reliable water flow control in residential or light commercial refrigeration systems. The AC operating voltage enables compatibility with typical household electrical circuits and refrigeration units.
Features: 110V AC; 1/4″ inlet; metal/plastic construction; suitable for RO systems.
APPLI PARTS APVI-1111 Single Water Inlet Valve
This 120V solenoid valve is designed for refrigerators and ice makers, featuring a 3/4″ NPT inlet and 1/4″ outlet. It operates at 50/60 Hz with a current draw around 0.95 A, making it a practical replacement for common refrigeration plumbing connections. The universal compatibility allows substitution for different brands when input power is the same, though water connections may vary.
Features: 120V; 3/4″ NPT inlet; 1/4″ outlet; universal compatibility with same input power.
Buying Guide
Key purchase considerations help buyers align a valve with refrigeration needs:
- Voltage and electrical compatibility: Match DC or AC requirements to your system. DC valves are common in compact or battery-powered setups, while AC valves fit standard household circuits.
- Inlet/outlet size and threading: Verify 1/4″ or 3/4″ NPT, and ensure the valve’s ports align with your plumbing and filtration components.
- Material and compatibility: Brass bodies with Viton gaskets offer durability and chemical resistance; avoid brass valves for potable water when drinking water contact is required.
- Fluid compatibility: If the system uses refrigerants, oil, or fuels, confirm the valve’s seals and materials tolerate those fluids.
- Environment and temperature: Temperature tolerance matters for steady operation in freezers or high-ambient conditions.
- Installation and maintenance: Look for valves with straightforward mounting hardware and reliable seals to minimize leaks and downtime.
- Reliability and life cycle: Valves rated for high cycle counts suit ongoing refrigeration use where frequent switching occurs.
Operational perspectives vary: direct-acting valves respond quickly and suit compact systems, while dual-solenoid configurations simplify multi-function refrigeration lines. For DIY projects, compatibility with common brands and ease of installation can save time and reduce the need for adapters. For commercial setups, prioritizing durability, temperature tolerance, and warranty coverage is often more important than initial cost.
