China hydraulic gripper valve leak tester Manufacturer, Factory, Supplier

Yufeng Machinery factory's Split Safety Valve Pressure Calibration Test Bench is a single-station design specially developed for flange-connected and thread-connected spring-loaded safety valves. This bench integrates shell strength testing, valve seat seal testing, opening pressure setting, reseating pressure verification, and low-pressure air tightness inspection in one unit, offering easy operation and reliable results for factory QC and maintenance workshops.

Yufeng Machinery strictly implements ISO9001 quality management system in production, relying on decades of R&D and manufacturing experience of valve testing equipment to launch the DN1200 Horizontal Hydraulic Top Press Valve Test Bench (Model YFJX-H). The whole machine fully complies with GB/T13927-2022, GB/T26480-2011 and API 598 international valve testing specifications, and is specially customized for large-diameter industrial flanged straight-through valves.

Manufactured by Wenzhou Yufeng Machinery, the DN800 Variable Speed Rotary Worktable For Valve Grinding is a frequency conversion adjustable-speed electric rotary workbench specially matched for large-diameter valve grinding equipment.

This heavy frame hydraulic press targets the manufacturing of PTFE corrosion resistant lined valves It carries out lining lamination compaction and curing work It makes fluoroplastic lining closely attach to valve body to stop void and peeling With adjustable pressure and holding cycle it fits multiple lined valve sizes for chemical valve production lines

Developed and manufactured by Yufeng Machinery under a strict ISO 9001 quality management system, the Horizontal Side Clamping Jaw Special Hydraulic Test Bench for Check Valves is a customized dedicated testing equipment exclusively designed for check valve structural characteristics. It thoroughly solves the long-standing pain points that conventional universal valve test benches cannot clamp special-structure one-way check valves accurately and lead to inaccurate inspection results.

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.
