2KWA Series Normally Open Solenoid Valve – Internally Piloted Brass Valve for Air, Water and Oil 1/2”–1”

Specification 2KWA (Internally piloted):

Product Description – 2KWA Series Normally Open Solenoid Valve (Internally Piloted)

The 2KWA Series solenoid valve is a 2/2 way normally open internally piloted valve designed to control the flow of air, water, and oil in industrial fluid systems. In its default state, the valve remains open, allowing fluid to pass through; when energized, the valve closes to regulate the flow.

With its internally piloted mechanism, the valve is capable of handling larger flow rates and operating efficiently under pressure conditions, while reducing the electrical load on the coil. The valve body is made from high-quality brass, providing excellent durability, corrosion resistance, and long service life.

Key Features and Characteristics

1. Normally open 2/2 way design allowing fluid flow when not energized.
2. Internally piloted structure for stable operation and high flow capacity.
3. Durable brass body with excellent corrosion resistance.
4. Coil protection rated IP65 for dustproof and waterproof performance.
5. Class F insulation coil for improved thermal resistance.
6. Compact and robust design for easy installation and maintenance.
7. Compatible with PT, G, and NPT thread standards.
