Product Overview
The 2SA Series Solenoid Valve is a 2/2 way normally closed internal pilot operated valve designed to control the flow of water, air, and industrial fluids in pipeline systems.
When the coil is energized, the magnetic field activates the pilot mechanism and allows the valve to open. When power is removed, the valve automatically closes using spring force.
The valve body is made of SUS304 stainless steel, providing excellent corrosion resistance, durability, and long service life for industrial applications.
Key Features
• Internal pilot operated design ensures fast response and high flow capacity.
• SUS304 stainless steel body provides strong corrosion resistance and durability.
