ZJHQ Valve Technology Group was founded in 1992 and is committed to providing high-quality, high-value-added valves and related fluid control products and services for the energy industry. After more than 20 years of innovative management, it has now developed into one of the valve industry production and sales companies with 8 professional companies, 15 holding companies, and more than 50 professional cooperative factories. The products are used in nuclear power, thermal power, petroleum and petrochemical, coal chemical and other series of valves, and have a large brand awareness and reputation in the power station industry and the petroleum and petrochemical industry.
ZJHQ has professional production lines for power station valves, regulating valves, ball valves, butterfly valves, general valves, forged steel valves, anti-corrosion valves, and breathing valves. It can produce high-end valves such as special valves for power station systems, special valves for petroleum and petrochemical systems, hard-sealed wear-resistant ball valves, pneumatic, hydraulic and gas-liquid linkage quick closing butterfly valves, and general high and medium pressure gates, cuts, stops, balls, butterfly valves and other products. Provide valve products that meet various complex working conditions such as high temperature, high pressure, sulfur resistance, corrosion resistance, and erosion resistance. There are hundreds of product categories and tens of thousands of product specifications.
ZJHQ is a Chinese high-tech enterprise, a governing unit of the Valve Branch of China General Machinery Industry Association, a key backbone enterprise in the Pump and Valve Characteristic Industrial Park of the National Torch Science and Technology Industrial Park, a demonstration enterprise of China's manufacturing informatization and a demonstration enterprise of credit management.
The ZJHQ Technology Center was rated as a provincial valve technology center, and its research and development results have obtained 52 national utility model patent certificates and 10 provincial-level industrial new products. The group company became a member of the National Valve Standards Committee and a member of the Power Plant Valve Standards Committee of the power industry, and participated in the drafting and formulation of dozens of national or industry valve standards.
ZJHQ has successively developed 36 kinds of high-tech products such as control valves for power station steam turbine bypass systems, high and low pressure bypass devices, nickel-based alloy valves for petroleum and petrochemicals, wear-resistant ball valves for coal chemical industries, and temperature and pressure reducing devices. "The new product, including the accumulator type 0.3-second quick-closing butterfly valve, is listed as a project of the National Torch Program.
In April 2006, the nuclear level 2 and level 3 globe valves independently developed and manufactured by ZJHQ formally passed the joint appraisal by the Expert Appraisal Committee organized by China Machinery Industry Federation and Zhejiang Economic and Trade Commission. ZJHQ became the first nuclear power plant in ZJ Province. A high-tech enterprise with valve design and manufacturing capabilities.
