Tailonz 1/4″ DC12V 3V210-08 Solenoid Valve
The Tailonz 3V210-08 is a two-position, three-way valve operated by DC12V. It features a straightforward outlet-wire connection and supports a working pressure range of 25 to 116 Psi. The valve is designed to stay open when the coil is de-energized and close when energized, enabling reliable on/off control in pneumatic lines or light-fluid systems. This model is suitable for compact automation tasks where a 1/4″ port size and DC control are preferred.
Tailonz 1/4″ AC110V 3V210-08 Solenoid Valve with Junction Box
This version mirrors the 12V model but uses AC110V, and includes a junction box for easier practical wiring. The valve remains open when de-energized and closes when energized, with the same 25–116 Psi working pressure band. It is a solid option for projects that require AC control and a compact 1/4″ port size in a single-coil, 2-position, 3-way configuration.
Tailonz 3 Way 2 Position Hand Levers Valve 3R210-08
The 3R210-08 is a manual control valve intended for air or light fluids, with a 1/4″ NPT port and a 30 to 116 Psi working pressure range. The hand pull mechanism enables quick manual override in pneumatic lines or testing setups, offering a simple alternative when automation is unavailable or being tested. This model is appreciated in prototyping environments where occasional manual control is necessary.
uxcell 2 Position 3 Way DC 12V Solenoid Valve (2 Pack)
uxcell offers a compact 2-position, 3-way DC12V option in a two-pack format. Key specs include a 12V coil and a compact build designed for small-scale pneumatic or fluid-control projects. The kit includes two valves, making it convenient for dual-channel applications or parallel testing. The port details indicate suitability for small-diameter tubing and light-pressure systems.
Tailonz 3/8″ NPT 12V Solenoid Valve 4V310-10
This 4V310-10 model supports 2-position operation across a 5-way configuration, with multiple voltage options (12V/24V/110V/220V). It’s designed for broader control needs, including more complex pneumatic circuits or liquid pathways. The 3/8″ NPT size expands compatibility with slightly larger tubing, offering robust performance in medium-scale installations.
Bzsunway 3-Way 4 GPM Spool Valve Replacement
Bzsunway provides a 3-way, 4 GPM spool valve designed for SV08-30-0-N-00 compatibility and VC08-3 cavities. It emphasizes reliable continuous-duty operation with a continuous voltage range of 85% to 115% of nominal. This part is targeted at replacements in compact valve assemblies that require precise flow control and compatibility with standard 1/2″ hole solenoids.
MacMaxe 3-Way Solenoid Valve – ZB09 9W Coil
The MacMaxe ZB09 valve uses a 9W coil compatible with 110–120V systems and supports a 1/8″ outlet with conical fittings, suitable for espresso machines and smaller fluid circuits. It’s rated for temperatures from -40°C to 140°C and up to 20 bar. This model emphasizes compact size with a compact, robust coil suitable for appliance and automation projects requiring precise 3-way control.
Jiayin JYZ-3 Normally Closed 2/3 Way
The Jiayin JYZ-3 is a normally closed valve designed for higher-pressure lines, with a 1/8″ port and a high-pressure rating up to 15 bar. It operates on 110–120V AC and is commonly used in coffee and hot-water systems, as well as industrial fluid control. The model is compact and suitable for 2/3 way configurations where a built-in N/C behavior is desired for safe shutoff.
Buying Guide: Key Considerations for Solenoid 3-Way Valves
- Port size and thread compatibility: Confirm 1/4″ or 3/8″ NPT and verify port diameters align with your tubing or piping. Some valves offer 1/8″ ports for compact installations.
- Voltage and power: Choose DC coils (commonly 12V) for battery-powered or low-voltage systems, or AC coils (110V/220V) for mains-powered applications. Ensure the control voltage matches your driver or controller.
- Number of positions and ways: A 2-position, 3-way valve can switch between two flow paths. For more complex routing, consider 5-way variants or manual override options.
- Material and compatibility: Brass bodies are common for water/steam lines; plastics or coated metals suit air and light fluids. Check temperature ratings and chemical compatibility for your medium.
- Pressure and flow: Review the working pressure range and maximum flow (GPM or L/min) to ensure the valve can handle your system’s demand without leakage or sluggish response.
- Control features: Outlets with wire connections, junction boxes, or built-in manual levers add convenience for installation and testing. Manual overrides can be critical for debugging.
- Reliability and duty cycle: Look for continuous-duty coils and robust coil designs that tolerate long operation and brief surges without overheating.
- Maintenance and replacement: Uniform port standards and coil styles ease future replacements and compatibility with existing manifolds or controllers.
