H-47/48-21000 series pneumatic nuclear grade regulating valveDetailed product description：

The H-47/48-21000 series pneumatic nuclear grade regulating valve consists of a ∑ F actuator and a 21000 series single seat valve. The ∑ F actuator is a combination of a conventional spring film actuator and a force amplification system. It utilizes the lever principle to amplify the output force of the actuator by 2.6-5.2 times; The 21000 series single seat valve adopts a top guide structure to ensure stable operation of the valve core. This valve has good universality and can be used for controlling fluids such as boron containing plasma in nuclear power plants.

Key Features:
1. It has various valve cores, including quick replacement valve cores, low capacity valve cores, low noise and anti cavitation valve cores, with a wide range of applications.
2. Adopting a top guiding structure, with a large guiding area and good stability.
3. The leakage is small.
4. Equipped with a ∑ F actuator, capable of withstanding high pressure differentials.
5. The sealing surface of the valve core and seat can be welded with tungsten chromium cobalt hard alloy to improve the service life of the regulating valve.
