China multi connection end valve hydrostatic tester Manufacturer, Factory, Supplier

The Yufeng Machinery factory's Mini Compact Horizontal Hydraulic Top Pressure Valve Test Bench features a compact horizontal design with a top pressure cylinder, specially suited for small bore flanged, welded, or threaded valves (ball, gate, globe, check, etc.). It supports high pressure water up to 64.0 MPa and low pressure air from 4 to 7 bar for shell strength and sealing performance tests.

Yufeng Valve Machinery holds complete ISO9001 quality certification, and has developed the DN600 Medium Size Hydraulic Top Press Valve Test Bench after years of optimization on horizontal axial jacking testing equipment. The whole machine complies with GB/T13927-2022 and API 598 global valve inspection standards, perfectly matching the routine mass inspection demand of medium-sized flanged straight-through valves.

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.

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.

This dedicated rotary worktable is an auxiliary accessory for valve lapping machines. It holds valve discs, valve clacks and other workpieces and delivers steady, uniform rotation, cooperating with lapping heads for even circumferential grinding. Adjustable speed adapts to sealing face fine lapping of valves in different materials and sizes. Robust construction supports heavy loads. Compatible with multiple valve lapping units, it greatly improves lapping precision and processing efficiency for valve production and repair.

Yufeng Machinery factory’s Three Station Valve Disc Lapping Machine is specially designed for grinding and lapping sealing faces of valve discs and valve seats in gate valves, globe valves, check valves, and other industrial valves. It is equipped with three independent lapping stations, enabling simultaneous processing of multiple workpieces or sequential coarse grinding, fine grinding, and polishing operations to significantly improve production efficiency.
