U.S. Solid 1/4″ Stainless 12VDC NC Solenoid Valve
This valve combines durable stainless steel construction with a Viton seal for resistance to high temperatures and corrosive fluids. The normally closed design ensures immediate shutoff when de-energized, while rapid actuation (<1 second) supports precise control in high-demand systems. Suitable for water, fuels, air, and other fluids, it is designed for long life and reliability in challenging conditions, with a lifecycle well over a million cycles given proper care.
U.S. Solid 12V DC NC Solenoid Valve, 1/8″ Port
This valve from U.S. Solid features a Viton seal for enhanced chemical resistance and temperature tolerance. With fast actuation under 1 second, it provides reliable and instantaneous control when energized or de-energized. Its stainless steel body supports durability in water, air, and fuel applications, and engineers estimate a life cycle exceeding one million cycles with proper operation and maintenance.
12V Propane Lockoff/LPG Shut-Off Solenoid Valve 1/4″
Designed for safety-critical applications, this 12V DC solenoid valve supports LPG and air control with a 1/4″ connection. It ships with dual wiring (red and black) and is UL listed for automotive safety. The valve is engineered to operate across a wide temperature range (-40°F to 158°F ambient; -4°F to 122°F fluid), enabling dependable shutoff in diverse environments and systems.
API-SOLENOID AR5499 24V Fuel Shut Off Valve
API Electric offers a robust fuel shut-off solenoid with universal compatibility across model lines such as Cummins NTA855 and N14 M11 K38 K50 engines. Built from sturdy materials like brass, steel, or aluminum, it emphasizes durability and reliability in demanding diesel environments. The valve is designed to maintain secure fuel control, reducing waste and ensuring safe engine operation when shut off is required.
GLOCRORET 12V Fuel Shut Off Solenoid Valve
GLOCRORET offers a 12V solenoid compatible with Cummins 4B/6B/6C engines and other Bosch P7100 pump-equipped diesel configurations. Its mounting and connection specs (3-inch bolt spacing, 3-pin connector) support straightforward replacement in compatible engines. The valve is designed to operate reliably in diesel systems, providing precise shut-off control and sustained performance under heavy use.
Additional Models and Specifications
When selecting a solenoid shut-off valve, consider port size, voltage, and compatibility with your fluids. 12V models are common for automotive and small machinery, while 24V units suit larger systems. Check seal material (Viton vs other elastomers) for chemical exposure, temperature range, and anticipated lifecycle. Installation ease includes compatibility with existing fittings and straightforward electrical wiring.
Buying Guide: Key Purchase Considerations
- Application fluids and compatibility: Ensure the valve seals and body material match the fluids (water, gasoline, diesel, LPG) and environmental conditions.
- Valve size and port configuration: Choose the correct connection size (e.g., 1/8″, 1/4″, 1/2″) to fit existing lines and fittings.
- Voltage and actuation speed: Confirm the valve’s voltage (12V or 24V) and its response time to energized/de-energized states for your control system.
- Seal material and chemical resistance: Viton seals offer high temperature and chemical resistance but verify compatibility with your specific chemicals.
- Durability and lifecycle: Look for valves with long cycle life (often over 1 million cycles) for demanding or continuous use.
- Mounting and installation: Check mounting bolt patterns and connectors to ensure a simple swap or integration into existing assemblies.
- Safety ratings: For fuel systems, prioritize UL-listed or automotive-grade components to meet safety standards.
- Maintenance considerations: Consider ease of maintenance, replacement parts, and availability from reputable suppliers.
