Top Pressure Horizontal Valve Test Bench With Access Ladder

This Top Pressure Horizontal Valve Test Bench With Access Ladder is originally designed for performance test of welded end connection valves. Equipped with replaceable transition backing plates (optional configuration), it can be adapted to flange-connected and thread-connected valves synchronously, realizing multi-interface universal detection on one single device. Customers can independently select test media: clean water, compressed air or diesel oil to meet various industrial working condition inspection requirements. The machine is standard configured with low-pressure water filling pump, high-pressure booster pump and closed medium circulation water tank to realize cyclic utilization of test fluid and reduce daily operation consumption. 

Multiple functional modules are optional: intelligent test data management system, hydraulic air cooling system, automatic hydraulic unloading system, safety protective sliding door, etc. The applicable valve caliber and maximum test pressure can be fully customized according to on-site production demands. Core basic parameters: applicable range DN150-DN600, overall dimension 410018001500mm, total weight 12 tons, rated power 18KW. Built-in bilateral maintenance climbing ladders and safety guardrails, convenient for operators to inspect pipeline components and maintain equipment top structure safely. We can provide CE safety certification renovation, multi-language touch panel and 415V export voltage adaptation for overseas energy, pipeline and valve manufacturing enterprises.

Seven Core Differentiated Advantages

1.Dual Synchronous Hydraulic Cylinder Balanced Jacking Clamping Structure The core mechanical advantage of Top Pressure Horizontal Valve Test Bench With Access Ladder: two large-tonnage hydraulic cylinders run synchronously to output uniform axial clamping force, end-face compression mode makes valve flange stress evenly distributed, no eccentric deflection or local deformation during long-time high-pressure holding, suitable for heavy thick-wall industrial valves.

2.Three Connection Form Valves Universal Compatibility With interchangeable adapter backing plates, the bench supports welded butt valves, flange valves and thread end valves three mainstream connection types, solving the trouble of purchasing multiple single-purpose test benches for valve factories with diversified product lines.

3.Built-in Bilateral Maintenance Ladder & Safety Guardrail System Exclusive design of climbing ladders and protective frames on both sides of the bed body: operators can safely climb up to check upper pipelines, pressure pipelines and hydraulic fittings, convenient for daily maintenance, troubleshooting and overhaul work, greatly reducing equipment downtime.

4.Three Optional Test Media + Closed-loop Circulation System Water, air, diesel three media switchable; built-in large-capacity circulation water tank collects residual test liquid for repeated use, saving water resource cost and keeping the workshop ground clean without sewage accumulation.

5.Low-pressure Filling + High-pressure Stepped Boost Dual Pump System Low-pressure pump rapidly fills valve cavity and exhausts internal air; high-pressure pump performs graded pressure rise and constant pressure holding. PLC constant pressure control system compensates pressure loss automatically, pressure control precision ≤±1%, fully compliant with GB/T13927-2022 and API 598 multi-stage pressure holding standards.

6.12-ton Super Heavy-load Integral Welded Rigid Frame Ultra-thick steel plate one-piece welded bed frame, undergone stress relief annealing treatment, total bearing capacity up to 12 tons, stable and vibration-free under long-term continuous heavy-load operation, never frame bending deformation.

7.Modular Optional Intelligent Upgrade Suite Customers can freely select functional modules: data acquisition & electronic report export, hydraulic air cooling to reduce oil temperature, automatic pressure relief after test completion, fully enclosed safety protective door, etc., configure equipment according to actual production budget and inspection needs.
