Brass Solenoid 220V/AC - 20mm thread

The 2W-200-20 is a 3/4" (DN20) brass direct-acting diaphragm solenoid valve. It is normally closed and switches water, air, oil and fuels on and off automatically. Its zero-pressure design opens without needing line pressure, which makes it suitable for water treatment, RO systems and general fluid control.

Key Features:

Normally Closed (NC)
Stays closed when de-energised, helping prevent accidental flow or leaks.

Direct-Acting Operation
Opens and closes without a minimum line pressure, so it can be fitted in low-pressure lines.

Durable Brass Body
Corrosion-resistant brass construction with NBR seals as standard. A high-temperature (V) seal option is also offered.

Multi-Media Compatibility
Suitable for water, air, gas and light oil with viscosity up to 20 cSt.

Flexible Voltage Options
Available in 12V or 24V DC and 110V or 220V AC coil versions.

Flexible Installation
Compact body with 3/4" female pipe threads.

Technical Specifications:

Compatible Power Supplies:

• 12V or 24V DC supply matched to the coil version (check the current draw against the coil rating)
• 110V or 220V AC mains supply for AC coil versions

Applications:

The 2W-200-20 is suited to:

• Water control in RO and water purification systems
• Water treatment and general liquid shut-off
• Automatic control of air, fuel and oil lines
• Replacement or spare valve for existing installations

Please note:

• This valve is sold separately from any power supply, fittings or pump.
• Check that the coil voltage matches your supply before use.
• Fit a Y-strainer or filter upstream, as the manufacturer recommends for this series.
• Do not use it with media above the rated temperature or viscosity.
• Confirm the thread type (BSP/G or NPT/PT) matches your fittings.
• Normally open versions of the 2W series also exist, so confirm you have the normally closed one.
