2WA Series Internally Piloted Solenoid Valve – Normally Closed Brass Valve (1/2" – 1")

Specification 2WA (Internally piloted):

Product Overview

The 2WA Series internally piloted solenoid valve is a 2/2 way normally closed valve designed for reliable fluid control in large flow industrial systems. In its default state without power, the valve remains closed to block fluid flow. When energized, the electromagnetic coil activates the internal pilot mechanism to open the valve.

With its indirect acting design, the valve can control large flow rates with minimal electromagnetic force, making it energy-efficient and suitable for high-capacity industrial systems such as water supply, pneumatic control, and oil flow management.

Features and Characteristics

1. 2/2 way normally closed design for reliable flow control.
2. Internally piloted mechanism allows control of large flow capacity.
3. Valve body made from durable brass for excellent strength and corrosion resistance.
4. Designed for larger pipe systems and high flow applications.
5. Compact and robust construction for easy installation and maintenance.
6. Standard FPM-F sealing material for durability and temperature resistance.
7. IP65 rated coil protects against dust and water in industrial environments.
8. Supports PT, G and NPT thread connections.
9. Optional terminal or grommet electrical entry.
