Established in 1993, Guanfa Valve Manufacture Co., Ltd. is specialized China regulating valve manufacturer and distributor of valves, hoses, tubes and pipes. Our oem regulating valves are suitable for acid, alkali, water, steam, seawater, coal gas and natural gas. They are widely used in petroleum, chemical, paper making, fertilizer, brewing and metallurgy. The use of specialized software of Pro/E and CAD has shorted the P&D and trial manufacture cycle, and greatly improved the service life and dependability of products. Our high-quality products have been exported to the North Amercia, UK, USA, Germany, Italy, India, France, Australia, Japan.

It is performer products achieving the self-regulation through the self-force of the controlled medium and saving energy at the same time. The setting value of the pressure and temperature may be regulated freely in the process of operation which has the feature of quick opening flow. With a number of advantages such as the highly sensitive motion, stable controlled parameter, high-precision regulation, and small leak volume, the products are extensively applied to the automatic control for the pressure and temperature under various working conditions.
