Solenoid Valve Propane 12V With 180° Fitting
The FJXBYWM solenoid valve features a 1/4″ female NPT inlet and 1/4″ male NPT outlet, designed for propane in liquid or vapor form. Its 180° fitting angle enables installation in tight spaces such as RV compartments or vehicle interiors. The unit uses stainless steel and brass construction to endure heat and pressure up to 170°F, with a copper coil for reliable operation. The valve is built to shut off automatically when power is interrupted, offering immediate safety in mobile gas systems.
12 Volt Propane Lockoff Valve 1/4″ NPT
This 12V locking shut-off valve is UL listed for automotive use and supports a 1/4″ connection. It comes with red and black wires for direct DC operation and is rated for a wide ambient temperature range, making it suitable for RVs, ATVs, and other mobile gas applications. Its safety-focused design ensures reliable shut-off in case of power loss or emergency scenarios, helping to prevent propane leaks during travel or storage.
U.S. Solid 3/8″ Brass 12V DC Solenoid Valve
With a robust brass body, this 3/8″ valve is designed for high-temperature environments and various fuels including gasoline, diesel, natural gas, and air. It uses a Viton seal for resistance to heat and chemicals and delivers fast actuation, closing or opening in under a second when energized. The valve is suited for repeatable, high-cycle use and is not intended for drinking water projects, reflecting its optimized application in gas and oil systems.
U.S. Solid 1/4″ Brass 12V DC Solenoid Valve
This 1/4″ brass solenoid valve features a Viton gasket and direct-acting, normally closed operation. It offers fast response—opening or closing in under a second when energized—which enhances safety and control in propane lines. The brass construction supports higher temperatures and robust performance in automotive and off-grid systems; it is not recommended for use with drinking water or other water-based projects.
Beduan Brass 1/2″ 12V Solenoid Valve
The Beduan valve uses durable brass with a copper coil design and 1/2″ NPT port size. It is suitable for various gases and fuels and is designed to operate on 12V DC. The copper coil contributes to reliable actuation, while the brass body supports corrosion resistance and longevity in demanding environments such as propane systems on RVs or in workshops.
Buying Guide: Key Considerations For 12V Propane Shut-Off Valves
- Fuel compatibility: Ensure the valve is rated for propane liquid and/or vapor as required, along with any other fuels in your system. Some models also support natural gas or other hydrocarbons.
- Electrical properties: Check voltage (12V DC is common), current draw, and wire polarity requirements. Some units have non-polarized wiring for simpler installation.
- Port size and orientation: Common sizes include 1/4″ and 1/2″ NPT. Inlets/outlets, and the 180° fitting angle, can impact installation fit in tight spaces.
- Materials and seals: Brass bodies with Viton seals provide temperature and chemical resistance. For drinking-water related projects, avoid brass/Viton options not suited for potable use.
- Safety features: Automatic shut-off on power loss improves safety in mobile setups. Look for UL listings for automotive use and certifications appropriate to your region.
- Operating temperature and pressure: Confirm the valve can handle ambient temperatures and the expected propane system pressure. Products often specify maximum temperatures and pressure ranges.
- Durability and cycles: Valve life and cycle performance matter in environments with frequent on/off operation. Brass and stainless steel constructions typically offer longer life.
- Installation context: Consider space constraints, mounting options, and compatibility with RVs, generators, or remote gas lines to ensure a proper fit.
When selecting a 12-volt propane shut-off valve, balance safety features, material durability, and installation practicality. Review the manufacturer’s datasheets for exact electrical and mechanical specifications, and confirm compatibility with your existing gas lines and fittings. A well-chosen valve contributes to reliable operation and enhanced safety in mobile and off-grid propane systems.
