Developed and manufactured by Wenzhou Yufeng Machinery, the Large Bore Gate Valve Disc Grinding Machine is a special sealing surface grinding equipment exclusively designed for gate plates of large-diameter gate valves ranging from DN500 to DN2000.
Yufeng Machinery factory's DN600 Dual Station Hydraulic Butterfly Valve Test Bench features double‑station simultaneous testing, specially customized for butterfly valves and knife gate valves, greatly boosting factory inspection efficiency and cutting labor costs. It is equipped with multiple high‑precision pressure gauges, realizing precise pressure regulation and stable long‑time pressure holding for shell strength and sealing performance tests.
Yufeng Machinery DN600 Intelligent Horizontal Top Pressure Testing Station is designed for shell strength and sealing performance testing of flanged and welded gate valves, globe valves, check valves, ball valves, and other industrial valves.Hydraulic cylinder top pressure system provides axial sealing with minimal external force on the valve body.
Vertical Manual Screw Water Tank Air Tightness Test Machine is a vertical manual screw clamping valve air tightness tester with built-in water storage tank. Vertical Manual Screw Water Tank Air Tightness Test Machine adopts handwheel screw mechanism to clamp and seal valve end face. Vertical Manual Screw Water Tank Air Tightness Test Machine uses water immersion bubble method to check valve air leakage directly. Vertical Manual Screw Water Tank Air Tightness Test Machine is suitable for low pressure gas leak detection. Vertical Manual Screw Water Tank Air Tightness Test Machine has simple structure without external hydraulic power. Vertical Manual Screw Water Tank Air Tightness Test Machine is easy to operate with low cost, suitable for small valve factory, valve repair workshop and teaching test.
Yufeng vertical hydraulic valve test bench is developed for small and medium-sized industrial valve manufacturers. This equipment adopts vertical hydraulic structure and provides stable pressure testing for valve body and seat sealing inspection. The article introduces structure advantages, testing applications and customer value of Yufeng vertical hydraulic valve test bench.
Recently, many owners of valve repair companies contacted Yufeng Machinery for grinding equipment. They need machines for mechanical seal faces and ball valve ball & seat lapping. Planetary grinding machine and rotary worktable stand out for high efficiency, great finishing effect and greatly reduced floor space occupation.
Choosing the correct valve test bench relies on complete inquiry parameters. We summarize the critical specifications customers need to prepare before sending enquiries. We also clarify a common misunderstanding about API requirements: API 598 applies to valve testing standards instead of requiring API certification for the test bench itself.
Yufeng Machinery implements standardized FAT Factory Acceptance Test for valve test benches before delivery. All valve test benches follow ISO and API standards during FAT inspection. Customers or third-party inspectors can witness the whole FAT test. This article introduces the full FAT workflow, documentation and SAT site acceptance test for valve test benches.
Digital testing has become a major trend in the valve repair sector. Computerized valve test benches solve the defects of traditional manual testing, featuring automatic pressure control, real-time data logging and standard report export. Paired with planetary grinding machines and rotary worktables, they create a complete closed-loop solution for valve overhaul and inspection.
To meet the requirements of standardized pressure testing, factory quality inspection and working condition simulation tests for all types of industrial valves...
