The AC 220V 1/4 Inch Brass Electric Solenoid Valve (2W-025-08) is a high-performance electromechanical switch designed for the precise control of fluid and gas flow. At Electrapac, we recommend this industrial-grade valve for automated irrigation, water purification systems (RO), and pneumatic control setups across Bangladesh.

Product Overview

The 2W-025-08 is a Normally Closed (NC) valve, meaning the flow is blocked until an electrical current is applied. When the 220V AC coil is energized, it creates a magnetic field that lifts the internal plunger, allowing water, air, or gas to pass through. Its solid brass body and NBR (Nitrile Butadiene Rubber) seal ensure a leak-proof experience and excellent resistance to corrosion.

Key Features for Electrapac Customers

• Instantaneous Response: The direct-acting mechanism allows the valve to open and close in milliseconds, providing high-precision control for dosing or timing-sensitive applications.

• Heavy-Duty Brass Body: Unlike plastic alternatives, this brass valve is designed to handle higher pressure and physical stress, making it suitable for both indoor and industrial environments.

• Zero Differential Pressure: This valve can operate even at 0 PSI (Gravity Feed), making it ideal for draining tanks or low-pressure water systems.

• Pure Copper Coil: Built with high-quality enameled copper wire to prevent overheating during extended periods of operation.

• Universal 1/4" Port: The standard sizing makes it compatible with most RO water filters, pneumatic fittings, and small-scale plumbing setups available in Bangladesh.

Wiring & Installation Guide

Installing the Electrapac Solenoid Valve is straightforward, but directionality is critical:

1. Flow Direction: Look for the Arrow embossed on the side of the brass body. The fluid must flow in the direction of the arrow for the valve to function correctly.

2. Mounting Position: For maximum lifespan, install the valve with the Coil facing upward. This prevents sediment or moisture from settling in the plunger area.

3. Wiring: The 220V AC coil is non-polarized. Connect your Live and Neutral wires to the two main terminals. Always connect the third (middle) terminal to Earth (Ground) for safety.

Pro-Tip: Solenoid valves can get quite warm if left "ON" for several hours. If your application requires the valve to be open for long durations, ensure it is installed in a ventilated area, or use a timer to prevent the coil from burning out.

Primary Applications

• Automated Irrigation: Connecting to a timer to water rooftop gardens or greenhouses automatically.

• RO Water Filters: Managing the inlet water flow in industrial or domestic water purifiers.

• Pneumatic Systems: Controlling air flow for small DIY CNC machines or automated sorters.

• Aquarium Top-off: Safely replenishing evaporated water in large fish tanks.

• Liquid Dispensing: Creating automated filling machines for beverages or chemicals.
