ALH Series High Temperature Solenoid Valve

The ALH series high temperature solenoid valve is a 2/2-way normally closed valve designed for reliable control of high-temperature media in industrial systems. Utilizing a pilot-operated structure combined with a robust piston design, the valve ensures stable operation, fast response, and dependable sealing performance under demanding conditions.

This series is specifically engineered for applications involving steam, hot water, and heat-conducting oil, with a working temperature range up to 225°C. The stainless steel body and high-performance sealing materials provide excellent durability, corrosion resistance, and long service life.

The ALH series supports multiple voltage options (AC and DC) and can be customized for different industrial requirements. It is widely used in automation systems, thermal equipment, steam pipelines, and high-temperature fluid control applications where precise and reliable on/off control is essential.
