2W Series Normally Closed Solenoid Valve: Reliable Fluid Control


The 2W series is a versatile, direct-acting solenoid valve designed for controlling the flow of water, air, oil, and non-corrosive gases. Available in various sizes from 1/2" (4分) to 1" (1寸), these valves are essential components for irrigation systems, water treatment, and industrial automation.

Key Technical Features

  • Normally Closed (NC) Operation: The valve remains closed when de-energized and opens immediately when power is applied, ensuring safety and precision.

  • Direct-Acting Structure: Allows for quick response times and stable operation even at zero pressure (0 PSI).

  • High-Quality Brass Body: Constructed from industrial-grade brass for superior corrosion resistance and long-lasting durability.

  • Multi-Voltage Support: Choose between AC 220V for standard building power or DC 24V for safe, low-voltage control systems.

  • Nitrile (NBR) Seal: Standard high-quality seals provide excellent leak-proof performance for water and air under 80°C.

Available Sizes & Models

We offer a full range of 2W series valves to match your piping requirements:

  • 2W025-08 (1/4"): Compact control for small pneumatic or water lines.

  • 1/2" (4分 / DN15): The standard choice for domestic water pipes and small irrigation.

  • 3/4" (6分 / DN20): High-flow valve for medium-sized fluid systems.

  • 1" (1寸 / DN25): Heavy-duty valve for large-scale water distribution and industrial cooling.
