Adopting a hanging cage structure! Introducing a control valve primarily used for controlling high-temperature and high-pressure steam.
This is a highly reliable control valve model 48000, specifically designed for high-temperature and high-pressure applications that can withstand harsh conditions. It was developed primarily for controlling high-temperature and high-pressure steam, where there are concerns about cage deformation due to frequent thermal cycles and rapid temperature changes. The basic structure adopts a suspended cage design. By using a suspended cage structure, the seat ring is fixed directly to the body in a screw-in type. This makes the cage less susceptible to thermal effects, preventing leaks from the seat ring gasket caused by thermal cycles typically seen in standard retainer structures, as well as erosion of the gasket surface. **Features** - Highly reliable and capable of withstanding harsh conditions, specifically for high-temperature and high-pressure applications. - Suitable for applications beyond the range of models 21000, 41000, 21119HP, and 21119AHP (70119HP) control valves. - Applicable to gases other than high-temperature and high-pressure steam. *For more details, please refer to the PDF document or feel free to contact us.*
