2SA Series Direct Acting Solenoid Valve – Normally Closed 2/2 Way Valve for Air, Water & Oil

Specification 2SA Series:

2SA Solenoid Valve Product Description

The 2SA solenoid valve is a 2/2 way direct acting normally closed solenoid valve designed to control the flow of air, water, light oil, and other fluids in automation systems. When power is not applied, the valve remains closed; once the coil is energized, the valve opens and allows the fluid to pass through.

Thanks to the direct acting structure, the valve can operate reliably even when there is no pressure differential, making it ideal for precise and fast fluid control in automated equipment and industrial machinery.

Key features and characteristics

The valve uses a normally closed 2/2 configuration, ensuring the fluid flow is automatically stopped when power is lost, providing safe system operation.

The direct acting mechanism offers fast response and high sensitivity, allowing the valve to switch flow quickly and accurately.

This series provides a wide pressure range with multiple versions available:

1. X – Extra high pressure
2. H – High pressure
3. Standard version
4. L – Large flow capacity
5. T – Extra large flow capacity

The valve features a compact and lightweight design, making it suitable for installations where space is limited.

The valve body is made from SUS304 stainless steel, providing excellent corrosion resistance, durability, and long service life.

The coil features Class F heat resistance insulation and IP65 protection rating, ensuring stable operation in dusty or humid environments.

Users can choose between terminal or grommet electrical connection types depending on installation requirements.
