Solenoid Valve For Propane And Gas Systems
The Solenoid Valve from FJXBYWM uses a 1/4″ female NPT inlet and 1/4″ male NPT outlet, compatible with propane in liquid or vapor form, natural gas, diesel, gasoline, and air. Its 180° fitting angle helps it fit tight spaces typical in RVs, trailers, ATVs, and vans. The assembly emphasizes reliability with stainless steel and brass construction, designed to withstand heat and pressure up to 170°F. A copper coil provides robust operation, ensuring dependable shut-off when power is interrupted to prevent fuel flow in mobile setups.
Key points: 12V operation, automatic shut-off on power loss, durable materials, and 180° mounting flexibility. This makes it a versatile safety valve for mobile fueling and onboard propane systems, offering a quick, safe response if electrical power is lost or disconnected.
U.S. Solid 3/8″ Brass Electric Solenoid Valve
This 12V, normally closed solenoid valve features a low-power coil that starts around 19W and reduces to 10–13W as it heats. Built from industrial-grade brass and outfitted with a VITON gasket, it resists high temperatures and corrosive fluids, making it suitable for gasoline, diesel, kerosene, natural gas, and air. The brass body supports welding and durability in demanding projects, but it is not intended for drinking water applications. The VITON seal ensures reliable sealing under hot and chemical exposure conditions.
Considerations include electrical load management, compatibility with fuel types, and the suitable operating temperature range for your system. The valve’s direct-acting design ensures quick response times in line with safety requirements for fuel control in vehicles and machinery.
846639 Fuel Shut-Off Solenoid Valve
Designed for compatibility with a wide range of riding mowers and engines, the 846639 valve supports popular models from John Deere, Craftsman, Husqvarna, and Briggs & Stratton. It’s a straightforward replacement option that helps prevent fuel waste by interrupting flow when the ignition is turned off. Installation involves clamping the fuel line to stop leakage, removing the old solenoid, and threading in the new unit. This model focuses on ease of installation and broad engine compatibility for lawn and garden equipment.
Key considerations include verifying original part numbers, ensuring proper fuel-line clamping, and confirming electrical connections match the system’s wiring harness for reliable performance during operation and shutdown.
Fuel Shut Off Solenoid Valve For Cummins Engines
This valve targets Cummins NTA855 and N14 families, including NTA-19 variants, and lists compatibility with KT, KTA-19 parts as well as multiple Cummins P/N references. It includes an O-ring and inserts steel to prevent leaks. The 12VDC solenoid uses standard signaling for diesel engine fuel shut-off applications, with emphasis on proper mating with specified Cummins components. When replacing, verify the exact part numbers to avoid mismatches and ensure proper sealing and electrical operation for safe engine shutdowns.
Buckbock 1/4″ Inline Gas Valve For Small Engines
The Buckbock inline valve is an economical 1/4″ fuel shutoff solution designed for small engines and lawn equipment. It lists compatibility with John Deere AM36141, AM107340, and several Briggs & Stratton and Toro models, functioning as a replacement for several part numbers. The compact design supports simple integration into small-diameter fuel lines and ensures a reliable shutoff to prevent fuel drain during maintenance or after shutdown. Check that the part matches your model as listed in the product description before purchase.
Buying Guide: Key Purchase Considerations For Gas Solenoid Valves
- Voltage and coil power: Most automotive and mobile gas valves operate on 12V DC. Check the coil power draw to ensure your power source can supply peak current without overheating.
- Connection size and type: Confirm inlet/outlet sizes (commonly 1/4″ or 3/8″ NPT) and whether the valve is normally closed or normally open to meet your control logic.
- Fluid compatibility: Ensure materials (brass, stainless steel, copper coil) and seals (VITON or similar) are compatible with your fuel (propane, natural gas, gasoline, diesel) and temperatures.
- Pressure and temperature ratings: Verify operating and max-pressure ratings, plus temperature tolerance to prevent leaks or gasket failures in rugged environments.
- Safety and shut-off behavior: Look for automatic shut-off features on power loss, and assess how quickly the valve responds to loss of power for safe fuel termination.
- Installation considerations: Note mounting flexibility (like 180° fittings), ease of wiring, and whether the valve requires clamping or bypass steps during installation.
- Durability and maintenance: Choose valves with corrosion-resistant materials and robust internal coils; consider maintenance access and replacement part availability.
- Compatibility with equipment: For engine-driven or generator systems, confirm that the valve supports the intended fuel type and integrates with existing fuel lines and harnesses.
- Standards and safety certifications: UL-listed or other relevant safety certifications can indicate reliability and suitability for automotive or outdoor use.
When selecting a gas solenoid shut-off valve, prioritize compatibility with your fuel type and installation environment, along with a proven safety shut-off response. By comparing coil power, materials, and mounting options, you can choose a valve that ensures safe operation and reliable shut-off in daily use or emergency scenarios.
