Yufeng Valve Machinery is a professional manufacturer of valve inspection equipment with complete ISO9001 quality certification. We independently developed the YFJX-LQ DN100 Split Water Tank Horizontal Valve Test Bench targeting visual bubble leakage testing demand, adopting a split layout separating control main unit and diving water tank, which greatly improves workshop space flexibility and valve loading convenience.
Yufeng Machinery factory's Dual Station Safety Valve Calibration Test Bench features double-station simultaneous testing, specially customized for flange-connected and thread-connected safety 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 Dual Station Hydraulic Test Bench for Butterfly Valves is designed for DN250 to DN1200 wafer type, lug type, and flange type butterfly valves including concentric and eccentric types.
Dual station design allows independent or simultaneous pressure testing on two stations, greatly improving batch inspection efficiency.
Yufeng Machinery factory's DN80-DN300 Medium Horizontal Hydraulic Jaw Clamping Valve Test Bench is specially designed for shell strength and sealing performance tests on flanged end valves (ball, gate, globe, check, etc.) in the nominal diameter range DN80 to DN300. It supports both high‑pressure water (up to the corresponding test pressure, see table) and low‑pressure air (4 to 7 bar) as test media, enabling hydrostatic shell tests, high‑pressure liquid seal tests, and low‑pressure air tightness tests.
Manufactured strictly under ISO9001 quality management system by Wenzhou Yufeng Machinery, the Yufeng Machinery Horizontal Tiltable Jaw Clamping Valve Pressure Test Bench is specially developed for heavy-duty large-caliber flange valves, featuring a unique right-side 90° tiltable worktable design to solve the difficulty of inclined valve clamping and medium filling during testing.
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.
Ongoing investment in energy infrastructure upgrades and predictive maintenance has shifted the industry growth focus from new valve manufacturing to aftermarket repair and recertification. Standard compliance such as API 598 and ISO 5208 becomes mandatory for valve re-certification, which directly stimulates market demand for professional valve pressure testing and precision lapping equipment. Yufeng Machinery keeps pace with this industry shift, delivering matched equipment and one-stop technical services to help valve repair enterprises meet certification requirements and improve workshop efficiency.
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.
Learn international valve pressure testing standards and key factors to choose reliable Yufeng valve test bench. Yufeng valve test bench meets GB/T13927, API598 and EN12266 standards for valve shell and seat leakage 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.
Reliable valve testing and grinding equipment relies on strict full-process manufacturing control. We implement independent production management covering raw material verification, metal forming, precision welding, surface finishing, anti-corrosion coating and factory performance testing, to deliver stable, high-standard equipment for global valve manufacturers and repair workshops.
