Product Description
This product series consists of direct-acting two-position two-way solenoid valves with bi-directional functionality. Both ports can serve as medium interfaces, allowing forward and reverse flow, while featuring automatic check valve functionality. Designed and qualified in accordance with RCC-E, IEEE 323, IEEE 344, IEEE 382, EJ/T, and GB 3836 standards, these valves are suitable for control pipeline systems with nuclear-grade requirements in nuclear power plants and nuclear chemical facilities, as well as explosion-proof environments. They provide reliable control over media connection and blocking in pipelines.
