UNOX Electronic Drain Valve for Air Compressor
UNOX offers a timed drain valve designed for 1/2″ NPT to 1/4″ NPT configurations with adjustable ON and OFF settings. The timer lets users tailor drain intervals from 0.5 to 45 minutes and discharge durations from 0.5 to 10 seconds, optimizing condensate removal without wasting compressed air. The valve handles temperatures from 0°C to 80°C and up to 232 PSI, making it suitable for demanding shop environments. Brass construction within a robust design supports long-term reliability in heavy-duty applications.
Solenoid Valve DC 12V For Air CO2
This aluminum-bodied solenoid valve operates at DC 12V with a 1/8″ NPT port, designed for air or CO2 compressor lines. Its high-precision copper guide head contributes to a tight seal and reliable operation under typical shop air pressures. The unit is built to endure wide temperature ranges and up to 115 PSI, offering a compact, durable solution for compact systems or retrofit projects where space is a premium.
Plum Garden 1/4IN DC 12V 2 Way NC Valve
Plum Garden provides a 1/4″ DC 12V two-way normally closed solenoid valve constructed from stainless steel components. Notable features include mounting versatility with two threaded holes for easy positioning in any orientation, compatibility with zero differential operation (0 PSI VACUUM), and an ED encapsulated coil designed for continuous service. This makes it suitable for portable or fixed air systems looking for a reliable, tight-sealing valve.
Beduan 2-Way NC 110V AC Solenoid Valve
Beduan presents a 2-way normally closed solenoid valve rated for 110V AC with a 1/4″ NPT port. The valve features an anodized aluminum body that resists corrosion and supports a range of media, including air and light liquids. Operating temperatures span from 23°F to 176°F with a maximum pressure rating around 115 PSI, making it a practical choice for workshop air lines or compressor accessories that demand dependable, no-leak performance.
X AUTOHAUX Auto Car Air Conditioning Solenoid Valve
X AUTOHAUX offers a DC 12V solenoid valve designed for automotive air conditioning systems, compatible with a wide range of Toyota, VW, Audi, and other models. The valve uses a 1/8″ NPT port size and is built from durable materials to withstand automotive under-hood conditions. This makes it a versatile option when adapting solenoid control to mobile or shop-based AC or compressed air projects that integrate with vehicle systems.
Across these options, the common strengths include robust materials (aluminum or brass), solid port sizing (1/4″ or 1/8″ NPT), and a focus on reliable actuation under typical shop conditions. When selecting, consider voltage compatibility with your control system, the required port size, media suitability, and whether timed drainage or continuous control best fits your setup.
Buying Guide
- <strongVoltage And Control Type: Choose DC valves for battery-powered or controlled circuits (12V is common in portable setups). AC valves suit wall outlets and fixed installations. Timed drain valves (like UNOX) add condensate management, while standard solenoids provide on/off control for lines and actuators.
- <strongPort Size And Inlet/Outlet Configuration: Match the thread size (1/4″ NPT or 1/8″ NPT) to your piping and fittings. Ensure the valve orientation allows easy mounting in your system.
- <strongMaterial And Media Compatibility: Aluminum bodies are lightweight and corrosion-resistant; brass offers durability for wet or mixed-media environments. Check media compatibility (air, oil, water) to prevent sticking or leaks.
- <strongPressure And Temperature Range: Verify that the valve’s maximum pressure and operating temperature align with your compressor’s output and ambient conditions. Many shop valves handle up to 115–232 PSI and temperatures near or above 140°F (60°C).
- <strongReliability And Maintenance: Look for encapsulated coils for continuous duty, resistance to clogging from sludge, and easy replacement parts. For drainage, a timer might reduce maintenance by automating condensate removal.
- <strongApplication Fit: If you need automatic condensate drainage, prefer drain valves with adjustable ON/OFF timing. For direct actuation of actuators or air tools, choose a general-purpose solenoid valve with appropriate power and mount requirements.
- <strongInstallation Footprint: Consider mounting options, bracket compatibility, and whether the valve’s shape fits your panel or enclosure. A compact design aids in retrofits and crowded workstations.
- <strongWarranty And Support: Check manufacturer warranties and compatibility with your existing controllers or PLCs. Read user reviews for real-world performance and longevity.
