AMT Series 3/2 Nuclear Instrument Solenoid Valve

AMT Series 3/2 Nuclear Instrument Solenoid Valve

Introduction
This product series consists of pilot-operated 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.

Main Features

1. Equipped with a manual override device for manual operation under special conditions such as power failure or maintenance.

2. All rubber components are suitable for use in high-radiation and rapid temperature fluctuation environments.

3. High insulation class and protection level: The coil insulation class is H-grade and meets application requirements under LOCA (Loss-of-Coolant Accident) environmental conditions.

4. Suitable for applications under seismic conditions.

5. Compact size, lightweight, and flexible operation.
