Product Description
The AMB series comprises direct-acting, two-position three-way solenoid valves with internal thread connections, utilizing electromagnetic force for operation. These valves are designed and certified to meet RCC-E, IEEE 323, IEEE 344, IEEE 382, and EJ/T standards. They are specifically engineered for pneumatic and hydraulic control systems requiring nuclear-grade qualifications in nuclear power plants and nuclear chemical facilities, providing reliable control over media flow direction, switching, and distribution. Commonly classified as instrument solenoid valves in industrial applications.
