China Valve sealing test Manufacturer, Factory, Supplier

Yufeng Valve Machinery is a professional intelligent large-bore valve inspection equipment manufacturer based in China's Pumps and Valves Capital, focusing on Single Side Flip Hydraulic Jaw Clamping Horizontal Valve Test Bench PLC automatic valve pressure test system R&D, supporting full-automatic cycle testing, EPC pipeline project orders, large flange valve non-standard customization and global energy engineering procurement.

Manufactured under ISO9001 quality management system by Yufeng Machinery, the DN700 Dual Station Special Hydraulic Test Bench for Butterfly Valves is a dedicated double-station hydraulic clamping pressure testing equipment independently developed for mass production inspection of butterfly valves and knife gate valves.

Yufeng Machinery factory's Lightweight Horizontal Hydraulic Top Pressure Valve Test Bench is specially designed for DN100 to DN600 flanged, welded, and threaded ball valves, gate valves, and other valve body shell strength and sealing performance testing. It is equipped with an upper hydraulic cylinder that directly drives the sealing plate to press against the valve end face, achieving reliable axial sealing with minimal external force on the valve.

Yufeng Machinery is a professional DN50-125 Integrated Dual Purpose Valve Seat and Ball Sphere Lapping Machine manufacturer rooted in China Valve Capital, focusing on dual-spindle synchronous CNC lapping technology, hard seal valve sealing surface mirror finishing, flange flatness precision lapping, automated batch production, PLC closed-loop numerical control, heavy rigid bed structure, and long-term valve smart factory production line supporting orders.

Manufactured by Yufeng Machinery, the Vertical Manual Screw Water Tank Air Tightness Test Machine is a vertical manual screw clamping type water trough air tightness valve testing equipment, designed for basic air tightness inspection of small caliber valves.

DN600 Intelligent Horizontal Top Pressure Testing Station is a professional hydraulic test equipment for DN150 to DN600 heavy-duty flange valves. Adopts horizontal axial clamping and end face sealing structure, it minimizes deformation and external force on valve bodies. Equipped with intelligent digital pressure control and multi hydraulic protection devices, the machine supports water and 4-7 bar air pressure testing. It completes shell strength, high-pressure sealing and low-pressure air tightness tests efficiently. Fully compliant with GB/T13927 and API 598 standards, it ensures stable pressure holding and accurate test results for industrial valve factory inspection.
