TAILONZ 3/8″ NPT 3V310-10 Solenoid Valve
The TAILONZ 3V310-10 is a 2-position, 3-way solenoid valve designed for DC12V operation. It uses a pilot-operated mechanism and features an outlet wire connection. Working pressure ranges from 25 to 116 psi, enabling versatile use in compact pneumatic lines. The valve stays open when the coil is de-energized and closes when energized, making it suitable for fail-safe or fail-close arrangements depending on circuit design.
Key considerations include the valve’s NPT 3/8″ port sizing and the need for compatible tubing and fittings. The single-coil design reduces control circuit complexity, while the 12V operation aligns with standard automotive and industrial control systems. For installations with space constraints, confirm clearance around the coil and the side-mount options of your manifold.
TAILONZ 1/4″ NPT 3V210-08 Solenoid Valve
The 3V210-08 model from TAILONZ PNEUMATIC offers DC12V operation with a 1/4″ NPT port. It is a 2-position, 3-way valve with an outlet-wire configuration. The valve is rated for 25–116 psi, matching typical low-to-medium pressure pneumatic systems. Its compact footprint and standard porting make it a good choice for compact automation or insert-control in handheld tools and small machinery.
When selecting this valve, verify tubing ID compatibility and ensure the space around the coil is sufficient for heat dissipation and electrical access. Pilot-operated or direct-acting choices may affect response time, so assess your application’s switching speed requirements and power availability accordingly.
uxcell 2 Position 3 Way 12V Solenoid Valve (Two Pack)
uxcell’s miniature valve is designed for 12V DC operation and includes two identical solenoid units. It is a 2-position, 3-way valve with 3.5mm port connections and 4mm tubing compatibility. The package includes two valves, which is useful for multi-line projects or creating redundant paths in compact systems. The valve emphasizes lightweight construction with a compact footprint, suitable for small automation projects and educational kits.
Consider the tubing diameter and electrical harness length (11 cm wire length) when planning panel layouts. Heat generation is modest, but ensure adequate ventilation in enclosed panels. This option works well for hobbyists or prototypes where budget-conscious choices are valued without sacrificing core functionality.
TAILONZ 1/8″ NPT 3V110-06 Solenoid Valve
The 3V110-06 from TAILONZ PNEUMATIC offers a compact 1/8″ NPT porting solution for 12V DC operation with a 2-position, 3-way configuration. This small valve is designed for lightweight pneumatic tasks and is compatible with low-pressure ranges similar to the larger models. Its outlet-wire connection provides straightforward integration into existing 12V control circuits.
Ideal applications include inline control in small automation modules or portable equipment where space is at a premium. Ensure that the chosen tubing and fittings match the 1/8″ NPT porting and account for the coil’s electrical draw in your control circuit design.
Baomain 4V230C-08 5-Way 3-Position Solenoid Valve
The Baomain 4V230C-08 is a 4V230C-08 model with 5 ports and 3 positions, internally piloted and rated for DC12V. It operates within 0.15–0.8 MPa and uses PT threads for inlets and outlets. This internally piloted design provides precise control for more complex pneumatic circuits that require multiple exhaust and supply configurations in a single valve assembly.
Practical considerations include exhaust port sizing and compatibility with PT fittings. The five-port, three-position arrangement is well-suited for advanced automation tasks, but ensure your manifold supports PT connections and the pressure range aligns with your system’s operating limits.
RIH Pneumatics 4V310-10 12V 5-Way Valve
The RIH 4V310-10 is a 12V solenoid valve in a 5-way, 2-position configuration with a pilot-operated mechanism. It includes a DC12V coil and is designed for robust performance in higher-detail pneumatic systems, offering a balance of multiple outlets and a straightforward wiring scheme for control logic. The product spec highlights a commonly used 2-position, 5-way arrangement, suitable for complex valve routing in automated lines.
Applications that demand multiple controlled branches or venting paths can leverage this model. Check the connection types and ensure the port configuration matches your manifold, as well as the coil’s thermal characteristics under continuous duty if your system runs hot or at higher PSI levels.
U.S. Solid 1/4″ NPT 3 Way Valve
The U.S. Solid 1/4″ NPT 3-way valve is designed for DC 12V operation with a compact aluminum body and IP65 rating for protection against dust and water. It provides a practical solution for projects requiring a durable, weather-resistant switch in pneumatic systems. The device uses a 12V coil with a modest power draw and offers a reliable on/off plus venting arrangement essential for many automation routines.
When integrating, verify IP requirements for outdoor or workshop environments, and ensure the 1/4″ NPT ports align with your tubing and manifold dimensions. The combination of rugged construction and straightforward electrical wiring makes it a versatile choice for mid-sized installations.
Buying Guide: Key Purchase Considerations
- Porting and thread size: Match the valve ports (1/8″, 1/4″, 3/8″ NPT) with your tubing or fittings and confirm thread standards (NPT vs PT).
- Voltage and coil type: All models listed run on 12V DC. Consider whether a single-coil, dual-coil, or pilot-operated design best suits your control circuit and response time needs.
- Pressure range: Most valves support roughly 25–116 psi. Verify your system’s operating pressure and ensure the valve’s range fits without strain or leakage risk.
- Environment and enclosure: IP ratings (like IP65) and material (aluminum or brass) influence durability in dust, moisture, or outdoor applications.
- Electrical wiring:Outlet-wire configurations simplify wiring but check if your controller offers the necessary current and wiring harness lengths.
- Flow path and logic: 3-way valves can be used for venting, direction control, or toggling between two outputs. Ensure the chosen model aligns with your desired pneumatic logic.
- Maintenance and replacement: Look for valves with readily available seals and common coil types to simplify maintenance and part replacement.
- Space and installation: Evaluate the footprint, mounting options, and proximity to power supplies to prevent overheating or interference with moving parts.
In selecting a 12V 3-way solenoid valve, weigh the balance between compact size, porting compatibility, and intended control logic. For simple on/off use, smaller 1/8″ or 1/4″ valves may suffice, while more complex lines benefit from 3-way, 5-way configurations to manage multiple exhaust and supply paths in a single unit. Always confirm that your system’s electrical and pneumatic specifications align with the valve’s ratings to ensure reliable operation.
