2W21 2/2-Way Direct Acting Brass Diaphragm Solenoid Valve

The 2W21 is a versatile 2/2-way normally closed solenoid valve featuring a durable brass body and a direct-acting diaphragm mechanism. Designed for general-purpose automation, it operates effectively without requiring a minimum pressure differential. This valve is the industry standard for controlling neutral media such as water, air, gas, and low-viscosity oils, offering a perfect balance between cost-effectiveness and reliable performance.

Features

Constructed with a robust forged brass body and a direct-acting diaphragm, the 2W21 valve ensures reliable on/off control at zero differential pressure for water, air, and light oil applications.

✅Durable Brass Construction: The valve body is forged from high-quality brass, providing excellent resistance to corrosion and mechanical stress, making it suitable for a wide range of industrial environments.

✅Direct-Acting Technology: Features a zero-differential pressure design, allowing the valve to open and close instantly even at 0 bar (0 psi), ideal for gravity tanks and low-pressure loops.

✅Reliable Diaphragm Seal: Utilizes a high-performance diaphragm (standard NBR, optional EPDM/Viton) to ensure a tight, leak-free seal and longevity even with frequent cycling.

✅2-Way Normally Closed: Operates as a standard 2-position 2-way normally closed (NC) valve, opening when energized and closing when de-energized for fail-safe operation.

✅Versatile Media Compatibility: Engineered to handle diverse neutral fluids including water, compressed air, inert gases, and light oils, serving as a universal solution for automation needs.
