U.S. Solid 3/8″ Brass Electric Solenoid Valve
Best for: small propane lines and mobile setups where space is limited. This 12V DC valve uses a low-heat coil, starting around 19W and dropping to 10-13W as it warms. Brass construction offers corrosion resistance and weldability for higher-temperature applications. A VITON gasket provides chemical resistance against fuels and oils. Avoid using this unit with drinking water or water-based projects due to brass composition. Suitable for air, gasoline, diesel, kerosene, and natural gas in non-water applications.
Solenoid Valve, Propane 12v Solenoid Fuel Lock Off Valve
Best for: RVs, trailers, and other mobile propane systems needing automatic shut-off on power loss. It uses a 1/4″ NPT inlet and outlet with a 180° fitting angle to fit tight spaces. Built with stainless steel and brass for durability under heat and pressure up to 170°F. The valve instantly shuts off fuel flow when power is cut, adding a safety layer wherever the road takes you. Note that the inlet is female NPT and the outlet is male NPT, and wire polarity is not critical for operation.
Caution: Ensure compatible line fittings and avoid use with potable water systems since brass and seals are optimized for fuels.
U.S. Solid 1/4″ Brass Electric Solenoid Valve
Best for: compact propulsion or fuel lines where quick, reliable shut-off is needed. This 12V DC valve uses a VITON gasket for high-temperature and chemical resistance and is designed for fast actuation—opening or closing in less than a second. Brass construction provides durability and welding compatibility. It should not be used with drinking water. Suitable for gasoline, diesel, kerosene, natural gas, and air; recommended when space is a key constraint and rapid isolation is required.
Limitation: For drinking-water or potable-water projects, select a valve specifically rated for water use to avoid material incompatibility.
Datanly 12 Volt Solenoid Valve LPG Propane 1/4″ NPT
Best for: gas management with 1/4″ NPT connections in ambient environments up to 170°F. Stainless steel body offers longevity and corrosion resistance, while the 12V operation supports standard automotive and mobile setups. It handles propane in liquid or vapor form and supports low-pressure natural gas as well. Use this valve when you need reliable performance in rugged conditions and a compact footprint.
Limitation: Ensure correct orientation and wiring, and verify compatibility with your specific gas pressures before installation.
U.S. Solid 3/4″ Brass Electric Solenoid Valve
Best for: larger propane lines or higher-flow applications where robust actuation is required. This 110V AC valve uses brass construction for durability in higher-temperature projects and a VITON seal for chemical resistance. It closes or opens within a second of energizing or de-energizing, delivering quick isolation. Not designed for drinking water systems; ensure compatibility with fuel lines and appropriate voltage supply for safe operation.
Buying Guide: Key Considerations for Electric Propane Shut Off Valves
- Voltage and compatibility: Choose 12V DC for mobile setups or 110V AC for stationary installations. Check your power source and wiring compatibility.
- Port size and threading: Common options include 1/4″ NPT and 3/8″ NPT. Match to your hose and pipe fittings to avoid leaks.
- Material and seals: Brass bodies with VITON seals offer fuel resistance and high-temperature tolerance. Avoid uses with potable water unless specified.
- Actuation speed: Many valves open/close in less than a second, important for rapid shut-off in emergencies. Consider your safety requirements and system dynamics.
- Environmental limits: Temperature and pressure ratings affect performance. Ensure the valve is rated for the propane environment and your climate conditions.
- Fail-safety behavior: Some valves provide instant shut-off when power is cut. This is crucial for transportable fuel systems and safety-first designs.
- Installation space: Fittings with 180° angles can simplify installation in tight spaces. Confirm fitment with your layout.
Frequently Asked Questions
- What is the difference between 12V and 110V propane shut-off valves?
12V valves are common for mobile, RV, or generator setups, while 110V valves are typical for stationary, home, or workshop installations. - Can these valves handle LPG propane in both liquid and vapor form?
Many models are designed to handle both liquid and vapor propane, but verify the specification for your exact valve model. - Are brass valves safe for potable water?
No. Brass valves with certain seals are not suitable for drinking-water systems. Use water-rated valves if potable use is required. - Do these valves fail-safe if power is removed?
Several models offer automatic shut-off when power is cut, which enhances safety for mobile gas applications. - What should I consider for installation space?
Look for valves with 180° fittings or compact sizes to fit tight spaces, and confirm thread types match your piping. - Do these valves require special tools or adapters?
Most require standard NPT fittings; have the correct wrenches and thread sealant compatible with fuel lines.
