TAILONZ PNEUMATIC 4V210-08 DC12V 2-Position 5-Way Valve
Product Name: 2-Position 5-Way Solenoid Valve (Outlet wire). Voltage: DC12V. Working pressure: 25–116 psi. Operating range: 32–140°F. Working principle: When the coil is powered off, the valve stays open; when powered on, it closes. This configuration suits compact circuits with single coil actuation and high-flow needs.
TAILONZ PNEUMATIC 4V210-08 DC24V 2-Position 5-Way Valve
Product Name: 2-Position 5-Way Solenoid Valve (Junction Box). Voltage: DC24V. Working pressure: 25–116 psi. Temperature range: 32–140°F. Operating principle: Powered off keeps valve open; powered on closes, enabling straightforward control for pneumatic circuits with multiple actuators.
TAILONZ PNEUMATIC 4V210-08 AC110V Valve
Product Name: 2-Position 5-Way Solenoid Valve (Junction Box). Voltage: AC110V. Working pressure: 25–116 psi. Temperature range: 32–140°F. Working principle mirrors other 4/2 designs, offering solid integration into AC-powered control panels and larger systems requiring high duty cycles.
ASCO 8210G002-120/60, 110/50 Brass 4 Cv 2-Way
Product Name: Brass body pilot operated general service solenoid valve. Type: 2-Way normally closed. Port size: 1/2″. Orifice: 5/8″. Flow: 4 Cv. Voltage options: 120V/60 Hz and 110V/50 Hz. This valve is designed for robust industrial use with low leakage and high reliability across liquids and gases.
Baomain 4-Station Solenoid Valve Manifold (4V210-08)
Product Name: 4-Station Solenoid Valve Manifold, 24V DC, 5-Way 2-Position, 1/4″ PT ports. Includes manifold base and mufflers. This integrated design simplifies installation, reduces footprint, and speeds up wiring for multi-valve configurations in compact automation setups.
Beduan 2-Way Normally Closed DC 12V Valve
Product Name: 2-Way normally closed, 1/4″ NPT. Material: Anodized aluminum. Temperature range: 23–176°F. Pressure rating: up to 115 psi. Suitable for compact pneumatic circuits and simple actuation tasks requiring a single valve path.
Buyers Products BAV050SA 4-Way 2-Position Valve
Product Name: 4-Way 2-Position solenoid air valve with five 1/4″ NPT ports. Features allow remote control of pneumatic systems, with easy adaptability for tailgate cylinders and pneumatic operations in automotive or industrial contexts.
Buying Guide: Key Purchase Considerations and Comparisons
When selecting a 4/2 solenoid valve, consider voltage compatibility (DC vs AC), port size, and whether a junction box or manifold is needed for installation. Valve type matters: NC (normally closed) versus NO (normally open) configurations affect startup behavior and system safety. Pilot-operated vs direct-acting designs influence response time and pressure ranges. Durability factors include material (brass vs aluminum), seal type (NBR/Buna-N nitrile), and ambient temperature tolerance. For multi-actuator systems, manifolds simplify wiring and reduce space. Finally, ensure compatibility with your compressed air quality, coolant or contaminant exposure, and maintenance expectations. Compare units by flow coefficients (Cv), leakage rates, and service life ratings to match your application’s reliability and efficiency goals.
