U.S. Solid 1/4″ Brass Electric Solenoid Valve
This valve is made from industrial-grade brass, offering corrosion resistance and suitability for higher temperatures. It is compatible with various fluids including gasoline and diesel, but not appropriate for drinking water. The VITON seal provides high-temperature and chemical resistance, ensuring durability in demanding refrigeration environments. With a response time under one second, the valve closes or opens quickly when energized or de-energized, enabling precise control of refrigerant or auxiliary fluids in complex systems.
Randell RF VLV005 Liquid Line Solenoid Valve
Designed as a genuine OEM replacement part, this valve emphasizes efficiency and ease of use in commercial refrigeration systems. It is targeted at liquid line applications, providing reliable operation in standard refrigeration cycles. The unit typically ships as a single valve, suitable for integration into existing assemblies where space and compatibility with Randell components are priorities.
Refrigeration Syndicate Solenoid Magnet Tool And Cannister Case
This item functions as a diagnostic magnet/tool set to support troubleshooting of solenoid valves in HVAC and refrigeration systems. While not a valve itself, it aids technicians in quickly verifying valve actuation and diagnosing stuck or slow-opening solenoids, which can impact refrigeration performance and efficiency.
FJXBYWM Propane 12V Solenoid Valve
This 12V solenoid valve is built for fuel and gas lines, featuring stainless steel and brass construction for durability under heat and pressure. It offers a 180-degree fitting angle for tight spaces, making it useful in RVs, trailers, and other mobile refrigeration or propane-related applications. An automatic shut-off on power loss adds an important safety dimension to mobile refrigeration setups.
Beduan 2 Way Normally Closed AC 110V Solenoid Valve
Beduan’s valve is an AC-operated 110V unit with a 1/4″ NPT port, designed for air, gas, or liquid service. It provides a compact, robust solution for refrigeration line control, with temperature and pressure ranges suitable for moderate refrigeration environments. The anodized aluminum body supports durability in equipment enclosures and control panels.
Baerkian Refrigerator Water Inlet Valve Dual Solenoid
This dual solenoid inlet valve is designed to replace common 242252702 units in refrigerators, supporting both ice maker and water dispenser functions. It is a direct replacement part with mounting brackets and quick-connect fittings for straightforward installation. The dual solenoid design helps coordinate multiple water pathways within a fridge, contributing to efficient and reliable operation.
Buying Guide
Key purchase considerations help ensure you pick a valve that matches your refrigeration system needs. The following perspectives cover material, voltage, and compatibility to support informed decisions.
- Valve material and compatibility: Brass and stainless steel bodies offer good corrosion resistance and broad fluid compatibility, but always verify that the valve materials are compatible with the refrigerants, water, or oils in your system. For drinking water or potable water lines, select valves explicitly rated for potable use.
- Coil voltage and power: Common options include 12V DC and 110V AC. Confirm your control circuit’s voltage and available power supply to avoid mismatches that could prevent actuation or cause safety concerns.
- Port size and connection type: 1/4″ NPT is a standard size for many refrigeration components. Ensure the inlet/outlet threads and mounting style fit your existing manifold, fittings, and space constraints.
- Seals and chemical resistance: VITON (FKM) seals resist high temperatures and many fluids, but evaluate exposure to refrigerants, lubricants, or fuels. Some applications may require alternative elastomers.
- Temperature and pressure range: Look for valves rated to your system’s operating temperatures and pressures. Valves designed for home appliances may differ from those used in commercial refrigeration.
- Durability and lifecycle: A long lifecycle (over a million cycles) reduces maintenance, but ensure proper operating conditions and compatible lubricants to maximize longevity.
- Safety features: Automatic shut-off on power loss is a valuable safety attribute for mobile environments or critical lines where unintended flow could cause safety or contamination issues.
- OEM compatibility and installation: For replacements, verify model compatibility with existing equipment or brand-specific manifolds. OEM parts often ensure a smoother fit and reliable performance.
