DN600 Medium Size Hydraulic Top Press Valve Test Bench

This DN600 Medium Size Hydraulic Top Press Valve Test Bench adopts stable integrated bed frame structure and synchronous hydraulic jacking clamping system, the horizontal guide stroke can be adjusted freely to adapt to gate valves, ball valves and other mainstream medium-sized valves with different body lengths. It can complete long-time pressure holding leakage inspection for shell strength and sealing performance, equipped with precision pressure instruments, automatic constant pressure control system and hydraulic overload protection device, supporting free switching of water and air test media. 

Balancing load capacity, floor space and comprehensive procurement & operation cost, the bench is specially designed for standardized quality inspection procedures on medium valve production lines. The synchronous double hydraulic cylinder axial clamping structure provides uniform jacking force to avoid flange offset during long pressure holding; independent liquid and gas pressure regulating pipelines realize separate control of shell hydrostatic test and air tightness test pressure, with automatic pressure compensation function to keep test pressure stable.

 The integrated electrical control cabinet is equipped with multi-group shock-resistant pressure gauges and independent operation buttons, with simple operation and low daily maintenance difficulty. The thickened welded base effectively resists deformation under continuous medium load, and reserved PLC digital upgrade interface supports automatic test timing, pressure curve storage and electronic report export. We can provide full CE safety transformation and multi-language operation panel for overseas medium valve assembly factories and energy EPC workshops. If you need cost-effective horizontal axial jacking pressure testing equipment for DN50-DN600 medium valve batch offline inspection, contact our technical team to obtain full parameter sheet and long-term framework quotation within 24 working hours.

Seven Core Differentiated Product Advantages

1.Synchronous Double Cylinder Uniform Force Horizontal Jacking Clamping The core structural advantage of DN600 Medium Size Hydraulic Top Press Valve Test Bench: two hydraulic cylinders run synchronously to output balanced axial clamping force, no unilateral pressure deviation when clamping medium alloy steel valves, stable sealing positioning during long-time pressure holding, effectively avoiding inaccurate detection caused by valve displacement.

2.Wide-range Freely Adjustable Horizontal Guide Stroke Long horizontal integral guide rail, the clamping opening distance can be adjusted steplessly to fit short-body small-bore and long-body DN600 medium valves, one machine covers DN50~DN600 full medium valve specifications, reducing multiple equipment procurement investment for valve manufacturers, another core practical highlight of DN600 Medium Size Hydraulic Top Press Valve Test Bench.

3.Dual Water & Air Independent Medium Switchable Test System Built-in separate water injection booster pipeline and air intake pressure pipeline, matched with independent precision pressure gauges and pressure regulating valves, can independently complete shell water strength test and seat air tightness test, fully meet multi-medium multi-stage pressure holding inspection clauses of API 598 standard.

4.Compact Integrated Stable Welded Bed Frame Integral thick steel plate welded one-piece bed frame, small floor occupation compared with large-bore test benches, stable structure without vibration during continuous batch operation, suitable for medium-sized valve factories with limited workshop space.

5.Built-in Hydraulic Overpressure Automatic Protection Device Independent overflow protection circuit for hydraulic jacking system, automatically release pressure when clamping force exceeds set threshold, prevent valve flange deformation and equipment structural damage caused by over-clamping, meet EU CE industrial mechanical safety standards.

6.Simple Manual Centralized Control System with Low Operation Threshold Concentrated independent button operation panel, separate control of clamping, water boosting, air boosting and pressure relief functions, workers can complete the whole test process without complicated parameter setting, greatly reducing training cost for new operators.

7.Modular Intelligent Digital Upgrade Expansion Interface The central electrical cabinet reserves data communication expansion port, customers can later retrofit touch screen PLC automatic timing pressure holding, real-time pressure curve recording and batch electronic inspection report export function, realizing full digital traceability of production inspection data.
