About Yufeng – Valve Testing & Grinding Equipment Manufacturer
Wenzhou Yufeng Machinery Technology Co., Ltd. is a professional manufacturer specializing in valve test benches, valve pressure testing equipment, valve grinding machines, and valve lapping equipment in Wenzhou, Zhejiang, China.
Located in Wenzhou, one of China's major valve manufacturing centers, Yufeng has more than 20 years of experience in valve machinery manufacturing and customized equipment solutions. Our main focus is the development and manufacture of equipment for valve testing, pressure testing, sealing surface grinding and lapping, valve repair, refurbishment, and industrial maintenance.
Our equipment is designed for valve manufacturers, valve repair and service companies, industrial maintenance workshops, oil and gas service providers, engineering contractors, and other industrial users that require reliable valve testing and maintenance equipment.
Valve Test Benches for DN15–DN2200 Valves
Valve testing is one of our core areas of expertise. Our valve test benches can be designed and configured for valves ranging from DN15 to DN2200, covering a wide range of valve sizes, pressure classes, valve structures, and testing requirements.
Our valve testing solutions can be applied to various industrial valve types, including:
Ball valves
Gate valves
Globe valves
Check valves
Butterfly valves
Safety valves
Control valves
Other industrial valves according to customer requirements
Our product range includes hydraulic top-pressure valve test benches, claw-type valve test benches, horizontal valve test benches, vertical multi-station valve test benches, submerged valve test benches, safety valve test benches, and intelligent valve testing systems.
Depending on the valve type and application, our equipment can be configured for shell testing, seat leakage testing, pressure testing, and other specified valve testing procedures.
From DN15 small-bore valves to DN2200 large-diameter industrial valves, we can develop suitable testing configurations according to the customer's valve dimensions, pressure requirements, test medium, applicable standards, testing procedures, and workshop conditions.
Valve Grinding & Lapping Machines
Another major product line of Yufeng is valve grinding and lapping equipment for valve repair, refurbishment, and sealing surface maintenance.
Our valve grinding machines are designed for applications involving different industrial valve types and sealing components, including gate valves, globe valves, check valves, butterfly valves, ball valves, safety valves, and other valve-related sealing surfaces, depending on the machine configuration and tooling.
Our product range includes portable valve grinding machines, planetary valve grinding machines, and customized valve grinding and lapping solutions for different workshop and maintenance applications.
These machines are developed to support the preparation, restoration, and maintenance of valve sealing surfaces through controlled grinding and lapping processes.
For customers with different repair requirements, we can provide equipment configurations based on factors such as valve size, sealing surface structure, workpiece material, required grinding area, workshop conditions, and operating method.
Equipment for Valve Manufacturing, Repair & Maintenance
Our equipment can be used in a variety of industrial applications, including:
Valve manufacturing and production
Valve pressure testing
Valve repair and refurbishment
Industrial valve maintenance
Oil and gas equipment maintenance
Petrochemical and refinery maintenance
Power plant maintenance
Pipeline maintenance
Valve service workshops
Engineering and industrial maintenance projects
By combining valve testing equipment with grinding and lapping solutions, Yufeng can support customers across different stages of the valve maintenance and service process.
Customized Valve Machinery Solutions
Valve testing and repair requirements can vary considerably from one project to another. Valve type, size, pressure class, sealing structure, test medium, applicable standard, workshop layout, and operating method can all affect the required equipment configuration.
For this reason, we do not rely solely on a one-size-fits-all approach.
Our engineering and production teams work with customers to develop equipment configurations based on their actual application requirements. We can discuss valve specifications, DN/NPS range, pressure requirements, testing medium, applicable standards, clamping method, testing procedures, grinding requirements, workshop conditions, and other technical parameters before recommending a suitable solution.
This approach allows us to provide both standard equipment and customized valve testing and grinding machinery for different industrial applications.
Manufacturing, Factory Testing & Technical Support
As a manufacturer, Yufeng combines equipment design, mechanical manufacturing, assembly, testing, and technical support within its production process.
Before delivery, equipment can undergo factory inspection and testing according to the agreed technical requirements. We can also provide relevant technical documentation, operating guidance, installation and commissioning support, and spare parts assistance according to project requirements.
Our goal is not simply to supply a machine, but to provide equipment that can be integrated into the customer's valve manufacturing, testing, repair, or maintenance workflow.
Serving International Customers
With experience in international business and customized valve equipment manufacturing, Yufeng continues to develop cooperation with customers in different regions and industrial markets.
We welcome inquiries from valve manufacturers, valve repair workshops, industrial maintenance companies, oil and gas service providers, engineering contractors, distributors, and other professional equipment users.
If you are looking for a valve test bench, valve pressure testing machine, valve grinding machine, or valve lapping equipment, our team can evaluate your requirements and recommend a suitable configuration.
Please provide your valve type, valve size/DN or NPS, pressure range or pressure class, test medium, applicable standard, quantity, and intended application. Based on this information, we can discuss the appropriate equipment configuration and technical solution for your project.
Yufeng – Valve Testing & Grinding Equipment for Industrial Valve Applications.
Over the past three years, the global market for industrial valves and pumps has undergone significant changes. Based on customs statistics and international trade data, including data from the Observatory of Economic Complexity (OEC), exports of valves and liquid pumps from China have shown strong growth across several regions, particularly between 2023 and 2026. As global supply chains continue to evolve, demand for China made valves and pumps has increased significantly in a number of emerging and industrial markets.
