uxcell Miniature Solenoid Valve 2 Position 3 Way DC 12V
Brand: uxcell. Features include DC 12V operation, 0.2A current, and a 2 Position 3 Way configuration. Port 2 outer diameter is 3.5mm with 4mm tube fit, and Port 3 is 3.5mm. Wire length is 11 cm. This kit includes 2 solenoid valves. Best for compact, light-duty automation tasks or projects needing two independent outlets in a small footprint. Caution: data indicates a small current draw; ensure power supply matches 12V and can handle the total load.
TAILONZ PNEUMATIC 1/4″ NPT DC12V Solenoid Valve 2 Position 5 Way
Brand: TAILONZ PNEUMATIC. Configuration is 2 Position, 5 Way with DC12V operation. Designed for outlet wire configuration, it supports working pressures from 25–116°F and operating temperatures from 32–140°F. The valve closes when the coil is energized and opens when released. Best for projects requiring multiple air paths with a pilot-like action. Limitation: data notes a heat tolerance range; ensure ambient conditions stay within spec.
CNZG PNEU 2-Position 5-Way Solenoid Valve (DC12V)
Brand: CNZG PNEU. Includes a 1 piece 2-Position 5-Way valve with DC12V operation. The package lists additional PC fittings and mufflers, plus PTFE tape. This option is suitable for complete DIY pneumatic setups that need multiple ports and easy assembly. Best for builders who value a ready-to-use package. Caution: confirm compatibility of included fittings with your tubing to avoid leaks.
uxcell AC 24V 3 Way 2 Position Solenoid Valve 1/4″ PT
Brand: uxcell. This unit uses AC 24V, 3 Port 2 Position design, with 1/4″ PT ports. It has a universal design aimed at smooth operation and good heat dissipation. Best for applications where AC control is preferred or required. Limitation: listed as 3 Port 2 Position, so ensure your circuit matches a 3-way configuration rather than a strict 2-way path.
TAILONZ PNEUMATIC 1/4″ NPT DC24V 2 Position 5 Way Solenoid Valve
Brand: TAILONZ PNEUMATIC. Features a 2-Position 5-Way valve with DC24V and outlet wire configuration. It supports operation within typical pneumatic ranges and follows the “when coil is powered off, valve remains open; when powered on, it closes” principle. Best for systems needing multiple exhaust and supply paths with reliable switching at 24V. Caution: verify coil voltage compatibility with your control system to avoid coil burnout.
TAILONZ PNEUMATIC 1/4″ NPT 12V 2 Position 2 Way Solenoid Valve
Brand: TAILONZ PNEUMATIC. Model 2V025-08, 12V DC, 1/4″ NPT, 2 Position 2 Way. The valve operates with a straightforward open-on-off control and is suited for compact lines and simple logic tasks. Best for small, low-pressure systems where minimal complexity is desired. Limitation: only two ports in this specific model, limiting path options in more complex circuits.
TAILONZ 1/4″ NPT DC24V 2 Position 5 Way Solenoid Valve
Brand: TAILONZ PNEUMATIC. Features a 2-Position 5-Way valve with DC24V and outlet wire. Operating principle mirrors other 5-Way variants, with closed when energized. Best for multi-branch circuits needing extra outlets and exhaust paths. Consideration: ensure supply voltage matches your control logic; mis-match can impair correct operation.
Buying Guide
What to consider when choosing a 2 position solenoid valve:
- Voltage and power: Match coil voltage to your control electronics (DC12V, DC24V, or AC options).
- Port configuration: 2 Position valves come in 2-Way, 3-Way, or 5-Way arrangements. Choose according to the number of flow paths you need.
- Port size: Check tube and thread sizes (e.g., 1/4″ NPT or metric equivalents) to ensure compatibility with existing fittings.
- Material and duty: Consider environment, corrosion resistance, and heat management. Aluminum bodies typically offer good durability.
- Actuation behavior: Some valves open or close on power-off or power-on. Select the behavior that matches your control logic.
- Included components: Some bundles include fittings, mufflers, or PTFE tape—helpful for quick setups.
- Physical footprint: For tight installations, measure valve dimensions and mounting options to avoid interferences.
FAQs

- Can I mix valves with different voltages?
A valve with two stable states that switches flow paths when the solenoid is energized or de-energized, enabling simple on/off control of pneumatic or hydraulic lines.
DC12V models typically draw less power than higher-voltage options, but always verify compatibility with your drive electronics and power supply capabilities.
A valve with five ports, allowing multiple flow paths and exhaust routes. Common in more complex pneumatic circuits.
Bundles with fittings and PTFE tape can save setup time, but confirm that included parts match your tubing and thread standards.
Use appropriate thread sealant or PTFE tape as specified, and ensure fittings are tightened to manufacturer recommendations without over-tightening.
Not recommended. Use a single-coil voltage for all valves in a given control loop to avoid inconsistent switching behavior.
