CLSR2U Fuel Shut-Off Solenoid
The CLSR2U solenoid interrupts fuel flow when the ignition is turned off, making it suitable for riding mowers and lawn equipment that require reliable shut-off control. Best for homeowners and small fleet maintenance where authentic OEM-like behavior is needed. The part replaces B&S 846639 in many setups and covers multiple engine families listed in the product features. A clear caution is to verify the exact OEM part number before purchasing to ensure compatibility.
U.S. Solid 1/4″ Brass Electric Solenoid Valve
Constructed in brass with a VITON gasket, this valve is ideal for projects involving gasoline, diesel, kerosene, and other fuels. It offers rapid actuation (open/close in under a second) and is designed for high-temperature environments with a long lifecycle. It is best for industrial or DIY fuel line projects where corrosion resistance and fast response are important. A limitation is that brass-related valves should not contact potable water systems.
APIELE Fuel Shut Off Solenoid Valve for Cummins Engines
This 12V solenoid is listed for Cummins M11 diesel engines and similar platforms, including other related part numbers. It’s a suitable choice for engine builders and fleet mechanics who need a direct replacement that aligns with Cummins signaling and valve interfaces. Choose this if the engine specifically lists compatible Cummins parts. A caution: verify exact part number compatibility before ordering, due to multiple similar SKUs.
U.S. Solid 3/8″ Brass Electric Solenoid Valve
This 3/8″ brass valve features a low-power coil designed to reduce heat generation while delivering reliable actuation. It’s well-suited for higher-flow fuel or air applications and is compatible with fuels and oils that brass components typically tolerate. It’s best for larger projects or installations needing a stronger flow control. Limitation: avoid use with potable water systems; ensure the wiring and power supply meet the coil’s requirements to prevent overheating.
GLOCRORET 12V Fuel Shut Off Solenoid
Designed for Cummins 4B/6B/6C diesel engines and related Bosch/engine setups, this 12V solenoid mounts with a 3-inch spacing and supports multiple connectors. It’s best for diesel engine owners seeking a robust shut-off solution that matches heavy-duty fuel pump interfaces. For best results, confirm mounting dimensions and electrical connector compatibility before purchasing.
Buying Guide: Key Considerations for Shut Off Solenoids
- Voltage and current requirements: Ensure the coil voltage (commonly 12V) matches your battery or power supply and that the control circuit can supply sufficient current without overheating.
- Inlet/outlet size: Match the valve port size (1/4″, 3/8″, etc.) to your fuel line or piping to avoid adapters that introduce leaks or flow restrictions.
- Material compatibility: Brass bodies and VITON seals are common for fuels and oils but are not intended for drinking water. Check chemical compatibility with your fluid.
- Mounting and space: Verify mounting hole spacing and connector types (single or multi-pin) to fit existing fixtures and wiring harnesses.
- Part-number matching: Many valves are listed as OEM or compatible replacements. Confirm the exact OEM or engine part numbers to avoid improper fit.
Frequently Asked Questions
- What is a shut off solenoid valve used for? It controls the flow of fuel or fluids by opening and closing the valve when energized or de-energized.
- How do I know if a valve will fit my engine? Check the part numbers, mounting dimensions, and line sizes against your equipment’s specifications.
- Are brass solenoids suitable for diesel fuel? Yes, brass with VITON seals is common for diesel and fuel applications, but confirm compatibility with your exact fluids.
- Can I use a solenoid valve for drinking water? No. Brass and VITON portions are not rated for potable water; use valves designed for drinking water systems.
- What maintenance helps solenoids last longer? Keep electrical connections clean, avoid overheating, and replace seals if there is any leakage or swelling.
