Beduan Brass Electric Solenoid Valve, 1/2″ 110V
This normally closed solenoid valve uses brass construction and a copper coil, designed for durability in water, air, gas, and oils. The 1/2″ NPT port size fits common residential and small commercial lines. Best for compact line setups where space is limited and a quick shutoff is required. Limitations include potential incompatibility with highly volatile chemicals not listed in the media range.
Triumilynn 1″ Electric Solenoid Valve
Designed for higher flow applications, this 1″ valve handles air, water, gas, diesel, and oils. It operates on 110V-120V AC and is normally closed with a diaphragm mechanism. Suitable for systems requiring quick response and greater throughput. Choose this if your piping is larger than 1/2″ or you need higher flow. Limitation: timing can vary with temperature and media viscosity.
U.S. Solid 3/4″ Brass Solenoid Valve
This 3/4″ valve combines a robust brass body with Viton seals, offering durability in water, air, or diesel lines. It features a 0.1–10 bar pressure range and a temperature span of -10 to 120°C, with precise control for consistent flow. Best for medium-to-large systems needing strong sealing and chemical resistance. Limitation: brass may not be suitable for drinking water projects.
U.S. Solid 1/2″ Brass Solenoid Valve
This normally closed valve uses brass with a Viton seal for broad chemical resistance and high-temperature tolerance. It offers precise flow control with a 0.1–10 bar range and -10 to 120°C, suitable for water, air, and diesel lines. Better for medium-size installations than 1/4″ options. Caution: not ideal for potable water systems.
Beduan 110V 1/4″ Inlet Water Solenoid Valve
This model is tailored for RO and pure-water systems with a 1/4″ inlet. It uses metal and plastic construction suitable for RO water lines. Best for compact feed lines in filtration setups. Limitation: smaller port size restricts flow in higher-volume systems.
XSPANDER 1/4 Inch Electric Solenoid Valve
1/4″ valve designed for air, water, or gas with 110V-120V operation and normally closed configuration. Notable for no polarity in connections and fast actuation. Best for compact, quick-response needs. Caution: timing can be variable; ensure mounting position supports coil cooling.
ASCO 8210G002-120/60,110/50 Brass Solenoid Valve
ASCO’s 2-way normally closed, brass-bodied valve offers high-flow capability for liquids, gases, and inert media. It is designed for durability and long service life with low internal leakage. Best for industrial applications requiring reliable cycling. Limitation: higher flow valves may be overkill for small, low-volume systems.
U.S. Solid 3/4″ Brass Electric Solenoid Valve
This valve is corrosion resistant and designed for higher-temperature projects, compatible with gasoline, diesel, oil, natural gas, and air. The Viton seal provides durability in harsh media. Best for non-potable, high-temperature environments. Limitation: brass should not contact potable water systems.
Buying Guide: 120V Solenoid Valves—Key Considerations
- Port size and thread type: Match your piping (1/4″, 1/2″, 3/4″, or 1″ NPT) to avoid adapters that add leakage risk.
- Media compatibility: Confirm the valve materials (brass body, Viton seal) suit water, oil, gas, or air in your system.
- Voltage tolerance: Look for 110V ± a small tolerance to ensure compatibility with your power supply.
- Operation style: Normally closed valves are common for safety — they shut off flow when de-energized.
- Temperature and pressure: Check operating range to avoid premature failure in high-temperature or high-pressure lines.
- Mounting orientation: Some valves tolerate any mounting position; others favor coil-up installation for heat management.
- Chemical exposure: Avoid brass valves with potable water sections if drinking water is involved.
Frequently Asked Questions
- What does normally closed mean for a solenoid valve? A normally closed valve stays closed when de-energized and opens when energized, providing immediate shutoff when power is cut.
- Can I use a 120V valve with 110V supply? Yes, most 110V-120V AC valves operate safely within typical tolerances of ±10%.
- Which port size should I choose? Select port size based on your plumbing needs: larger sizes (1″ or 3/4″) for higher flow, smaller sizes (1/4″ or 1/2″) for compact installations.
- Is Viton seal necessary? Viton seals offer excellent chemical and temperature resistance, ideal for oil, diesel, and aggressive media.
- Can these valves handle potable water? Some brass valves are not suited for drinking water; verify your model’s suitability before use.
- What maintenance is required? Regular inspection for leaks and ensuring the coil is kept clean from dust and moisture extends valve life.
