China metal smelting feed baler Manufacturer, Factory, Supplier

Yufeng Machinery DN100 Integrated Horizontal Submersible Hydraulic Axial Press Valve Test Bench is designed for DN15 to DN100 flanged, welded, and threaded gate, globe, check, and ball valves. Integrated submersible tank with high strength welded construction and strong corrosion resistance.

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.

This four column vertical hydraulic press adopts four column vertical structure with good integral rigidity stable operation and uniform pressure distribution. It is widely used in press fitting lining forming pressing calibration and moulding procedures during valve manufacturing. The precise hydraulic control system supports accurate setting of pressure speed and holding time. Customizable worktable adapts to lined fluorine valves ball valves butterfly valves and various valve parts forming and assembly

DN350 horizontal metal scrap hydraulic baler can press various waste metal materials such as cans paint buckets scrap iron scrap steel scrap aluminum scrap copper car shells and metal offcuts into solid briquettes. It is widely used in metal recycling and smelting fields. The compressed metal blocks are convenient for storage transportation and remelting, effectively improve feeding speed and working efficiency and cut down the cost of transportation labor and smelting.

DN300 Medium Hydraulic Jaw Gripper Clamping Valve Test Bench Double-station simultaneous testing, specially customized for butterfly valves and knife gate valves, greatly boosts Yufeng Machinery factory inspection efficiency and cuts labor costs Equipped with multiple high-precision pressure gauges, realizing precise pressure regulation and stable long-time pressure holding for shell strength & sealing performance test.

Yufeng Machinery DN300-600 Variable Frequency Single Seat Ball Grinding Machine is designed for precision grinding and lapping of valve spheres and seats in ball valves.Equipped with two independent grinding stations for simultaneous processing of valve sphere and seat. controlled system with frequency conversion drive for precise speed regulation and stable operation.
