Zhengzhou Valve Group Co., Ltd.
Zhengzhou Valve Group Co., Ltd
Integrated with R&D, production, sales, and service.
Deeply rooted in the valve industry, consistently committed to excellence, and building the century-old Zheng Valve Group.
Since 1998, the company has successively obtained ISO9001 quality management system certification, environmental management system certification, and occupational health and safety management system certification, as well as the National Special Equipment Manufacturing License (TS). Over the years, it has been repeatedly recognized as a “contract-abiding and credit-worthy” enterprise, a “quality-trusted unit,” a Level-II Metrology Compliance Certificate, a Supervisory Inspection Compliance Certificate, and a product recommended by the China Urban Water Supply Association. It has also been designated by Sinopec as a “Member Factory of the Sinopec Materials and Resources Market” and received the “People’s Republic of China Import and Export Enterprise Qualification Certificate” in 2001. The company’s flagship product—the double-eccentric metal-sealed butterfly valve—obtained a national patent in 2000, was recognized as a high-tech product by Henan Province, and was identified as a “Xiao Xing Huo” project by the Ministry of Science and Technology of China. To date, the product has been granted more than 30 national patents. Thanks to its superior performance and excellent after-sales service, the product has earned wide recognition from numerous users. The company’s sales scope has gradually expanded from its original focus on the steel and aluminum industries to include many other sectors such as gas, petroleum, water conservancy and hydropower, power plants, pumping stations, chemical industry, wastewater treatment, and heating systems.

CF Single-Flange Force-Transmitting Coupling
The flexible expansion joint with force-transmitting mechanism consists of a flanged flexible expansion joint, short pipe flanges, force-transmitting screws, and other components. The short pipe has a certain amount of axial displacement capability and can be adjusted according to the on-site installation dimensions during installation and maintenance. Under normal operating conditions, it can effectively transmit axial thrust throughout the entire pipeline. This not only improves operational efficiency but also provides a degree of protection for equipment such as pumps and valves.
C2F Double-Flange Force-Transmission Coupling
The double-flange force-transmitting coupling features a compact structure, a rational design, reliable sealing performance, and convenient installation and removal. Within a certain range, it can compensate for axial displacement of pipelines and transmit axial tensile and compressive forces. It also offers functions such as adjusting the maximum expansion and contraction amount and preventing pipe connections from loosening. This coupling can replace U-tubes, bellows, and other types of expansion joints, making it an ideal solution for addressing pipeline installation and expansion/contraction issues.
Elastic Seat Gate Valve Sectional View
For a long time, conventional gate valves commonly used in the market have generally suffered from leakage or rusting. Our factory has introduced advanced European technologies for rubber and valve manufacturing to produce resilient-seated gate valves that effectively overcome the shortcomings of conventional gate valves, such as poor sealing performance, elastic fatigue, rubber aging, and rusting. Resilient-seated gate valves achieve excellent sealing by leveraging the slight elastic deformation of the resilient valve disc, which provides compensatory action. These valves boast remarkable advantages including light operation when opening, reliable sealing, excellent elastic memory, and an extended service life. They can be widely used as regulating and shut-off devices on fluid pipelines in applications ranging from tap water and wastewater systems to construction, petroleum, chemical industry, instrumentation, pharmaceuticals, light textiles, power generation, shipbuilding, metallurgy, and energy systems.
