        The temperature and pressure reduction device is a form of thermal energy conversion. This device mainly regulates the pressure and temperature of high-temperature and high-pressure superheated steam delivered from power plants, boilers, thermal power plants, steam turbines, etc., so that the steam parameters can meet the requirements of downstream users. Power or thermal energy parameters. In this way, heat energy can be used rationally and the safety of pipe network and equipment can be ensured.       The temperature reduction and pressure reduction device generally consists of a temperature reduction system, a pressure reduction system, a safety protection system, a thermal control system and related accessories. The temperature and pressure reduction device produced by our company has a medium temperature up to 650 degrees Celsius, a pressure level from negative pressure to 2500lb, and a diameter from DN10 to DN2000.

        Hangzhou Zhelin Valve Co., Ltd. was established in 2005. It was formerly the branch of Zhejiang High and Medium Pressure Valve Factory. Later ,it became an independent professional manufacturing enterprise specializing in the manufacturing of temperature and pressure reducing devices, regulating valves and various metal valves. "Zhelin" brand temperature reducing and pressure reducing devices, "Zhelin" brand regulating valves, and "Zhelin" brand valves are currently domestic high-quality valve products. They have high-quality raw material selection and production technology, and  has a high reputation in the industry. visibility.

        The "Zhelin" brand was founded in 1993 and obtained the trademark certificate for the first time in 2008.      

         In the early years, the company produced gate valves, globe valves, check valves, butterfly valves and other general valves. Since 2005, it has focused on the design and manufacturing of regulating valves, temperature and pressure reducing devices and various high-parameter valves. In 2005, it obtained the domestic The first batch of TS certificates for pressure piping components and metal valve manufacturing certificates were issued, and the "Zhelin" trademark was registered in 2008. Since then, it has focused on valves and temperature and pressure reducing device products in the fluid control segment.

        For a long time, high-parameter valves used in China's electric power, metallurgy, petroleum and petrochemical, coal chemical and other industries have been imported from Western developed countries. Hangzhou Zhelin Valve Co., Ltd. is determined to produce high-quality high-parameter regulating valves and temperature and pressure reducing devices. , steam turbine auxiliary equipment supporting products, etc., replacing imported products with high-quality design and services, and following the national "One Belt, One Road" industrial policy to benefit brother countries in need of industrial support. The "Zhelin" brand was born in "Zhejiang", a province with strong private enterprises, and developed in "Lin'an" District of Hangzhou City, hence the name "Zhelin".
