2LA Series 2/2 Way Solenoid Valve – Normally Closed Internally Piloted Valve for Water and Steam Systems

Specification 2LA (Internally piloted):

Product Overview

The 2LA Series solenoid valve is a 2/2 way normally closed valve designed with an internally piloted operating mechanism to control the flow of fluids such as water, steam, and other industrial media. When the coil is energized, the electromagnetic force activates the internal pilot system, allowing the valve to open quickly and operate smoothly.

The valve body is made from SUS304 stainless steel and equipped with a PTFE high-temperature seal, ensuring excellent durability and resistance in high-temperature or high-pressure environments. With its compact structure, high sensitivity operation, and IP65 protection rating, the valve is widely used in many industrial automation systems.

Key Features and Characteristics

1. Internally piloted operation for fast and stable valve switching.
2. 2/2 way normally closed design ensures safety when power is lost.
3. Valve body made of corrosion-resistant SUS304 stainless steel.
4. PTFE (Teflon) sealing material suitable for high-temperature fluids.
5. Class H coil insulation for reliable and long-lasting performance.
6. IP65 protection rating for dustproof and waterproof protection.
7. Compact and lightweight design for easy installation and maintenance.
8. Available connection threads: PT, G, and NPT.
