Sleeve-Type High-Temperature High-Pressure Solenoid Valve

Sleeve-Type High-Temperature High-Pressure Solenoid Valve

Product Description
This product series consists of step direct-acting high-temperature high-pressure solenoid valves designed and qualified in accordance with ASME, RCC-M, RCC-E, RCC-P, IEEE 323, IEEE 344, and IEEE 382 standards. Suitable for process pipeline systems with nuclear-grade requirements in nuclear power plants and nuclear chemical facilities.

Key Features

1. Compensated rigid sealing pair structure for reliable performance under high temperature, high pressure, and thermal shock conditions

2. All rubber components withstand high radiation and rapid temperature variations

3. H-class coil insulation with LOCA (Loss-of-Coolant Accident) environmental compatibility

4. Excellent corrosion resistance: Stainless steel materials in contact with media ensure compatibility with land, marine, and special environmental conditions

5. Reliable valve position indication system providing accurate feedback of valve status

6. Certified seismic performance
