Introduction
This product series consists of direct-acting two-position three-way solenoid valves with internal thread connections. Designed and qualified in accordance with RCC-E, IEEE 323, IEEE 344, IEEE 382, and EJ/T standards, these valves are suitable for pneumatic or hydraulic control pipeline systems with nuclear-grade requirements in nuclear power plants and nuclear chemical facilities. They are used to control the connection, direction change, and distribution of media in pipelines. Such valves are also referred to as instrument solenoid valves in the industry.
