The H-ZDL-21000 series electric nuclear grade single seat regulating valve consists of two parts: the ML series electric actuator and the 21000 series single seat valve. The ML series actuator is a product that introduces technology from ROTORK, a British company. It has the characteristics of precise control, strong anti-interference ability, high shell protection level, and multiple auxiliary functions. 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. 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.
