The AL-150 safety relief valve is designed to release excess pressure and protect systems from overpressure. It is suitable for use with steam, air, hot water, cold water, oil, and other non-hazardous fluids. Its closed-type structure minimizes fluid leakage to the outside, while advanced manufacturing techniques enhance performance and precision.

■ Features
- Compatible with a wide range of fluids, including steam, air, water, and oil.
- High performance with precise pressure control and advanced manufacturing techniques.
- Key components (valve seat and disc), as well as the pressure adjustment spring, are made from stainless steel SCS14A (equivalent to SUS316), ensuring excellent corrosion resistance.
- Closed-type structure prevents fluid leakage to the external environment.
