China Valve Test Benches Supplier

Yufeng Machinery, a professional valve testing equipment manufacturer based in China's Valve Capital, strictly produces testing machines under an ISO 9001 quality management system, fully complying with GB/T13927-2022, GB/T26480-2011 and API 598 international valve inspection standards. Our factory independently develops this DN100 Hydraulic Jaw Gripper Clamping Valve Test Bench integrating hydraulic clamping, mechanical positioning, electrical automatic control and medium storage circulation into one integrated unit.

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 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 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.

Yufeng Valve Machinery is a professional intelligent large-bore valve inspection equipment manufacturer based in China's Pumps and Valves Capital, focusing on CNC Single Side Flip Hydraulic Jaw Clamping Horizontal Valve Test Bench CNC 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.

Yufeng Machinery factory'CNC Automatic Horizontal Hydraulic Axial Press Valve Test Bench features a horizontal frame with a built‑in water tank and a CNC hydraulic system. The top pressure cylinder directly presses sealing plates against both valve ends for axial sealing, eliminating bending or side forces. The dual‑pump water supply system combines high‑flow filling with low‑flow high‑pressure boosting.
