DN1200 Horizontal Hydraulic Top Press Valve Test Bench

This DN1200 Horizontal Hydraulic Top Press Valve Test Bench integrates hydraulic clamping mechanism, mechanical positioning frame, electrical automatic control system and test medium circulation storage system into one integrated horizontal unit, featuring reasonable overall structure, complete functional modules, stable long-running performance and high automatic operation level. It is applicable to comprehensive performance tests including high, medium and low pressure shell strength and bidirectional seat tightness of flanged straight-through valves with nominal diameter DN300~DN1200. 

Adopting large-tonnage double-end hydraulic axial top pressing clamping structure, the equipment provides stable constant clamping force for extra heavy large-bore valves; the horizontal layout avoids the safety risk of vertical hoisting oversized workpieces, and the adjustable horizontal guide rail stroke can match valves with different body lengths. The independent multi-channel pressure control system separately controls shell water pressure test and air tightness test pressure, with automatic constant pressure compensation function to ensure test pressure stays stable during long holding periods. 

The independent digital control cabinet is equipped with multi-group high-precision shock-resistant pressure gauges and touch screen data recording module, which can store test pressure curve and export electronic inspection reports. The thickened integral welded base frame can bear long-term heavy-load impact without deformation, matching mass inspection demands of large valve manufacturing factories, petrochemical pipeline equipment plants and power station maintenance workshops. We can provide complete CE safety transformation, multi-language operation panel and 415V export voltage modification for overseas large-scale valve EPC production bases. If you need high-load large-bore horizontal axial top pressure valve testing equipment for mass delivery inspection, contact our technical team to obtain full technical data sheet and long-term framework quotation within 24 working hours.

Seven Core Differentiated Product Advantages

1.Large Tonnage Double-end Hydraulic Axial Top Press Clamping Frame The core load-bearing advantage of DN1200 Horizontal Hydraulic Top Press Valve Test Bench (Model YFJX-H): double large hydraulic cylinders provide bidirectional synchronous jacking force, sufficient clamping tonnage to lock DN300-DN1200 extra heavy alloy steel valves firmly, no flange slipping or displacement under high test pressure, solving the insufficient clamping force pain point of small and medium test benches for large bore workpieces.

2.Ultra-long Adjustable Horizontal Guide Rail Stroke Extended integral horizontal guide rail, freely adjust clamping opening distance to adapt ultra-short body and super long body large flanged valves, one machine covers full DN300~DN1200 specification range, cutting multi-equipment procurement cost for large-scale valve manufacturers, another core structural highlight of DN1200 Horizontal Hydraulic Top Press Valve Test Bench (Model YFJX-H).

3.Dual Water & Air Independent Circulation Test Medium System Built-in independent large-volume circulating water tank and high-pressure air intake pipeline, realize shell hydrostatic strength test and bidirectional seat air tightness test on one machine, separately equipped with high-pressure boosting pumps for liquid and gas media, fully meet multi-medium multi-stage pressure holding inspection clauses of API 598 standard.

4.Heavy-duty Thickened Integral Anti-deformation Welded Base The whole machine base is welded with extra thick carbon steel plate as a whole, with reinforced triangular support at both ends of the clamping frame, long-term continuous heavy-load operation without frame bending and deformation, effectively guaranteeing the consistency of inspection data of large-diameter valves.

5.Touch Screen Digital Full-process Automatic Test Control Centralized touch screen PLC operation system, support one-click automatic test cycle, automatic timing pressure holding, real-time pressure curve storage and batch electronic report export; all pressure, time and protection parameters can be preset and stored, greatly reducing manual operation error rate.

6.Multi-layer Heavy-load Safety Interlock Protection Mechanism Equipped with hydraulic overpressure relief protection, mechanical limit anti-overtravel block, emergency stop power cut-off and overload stall four-fold safety interlock, automatically cut off hydraulic jacking and pressure output when abnormal conditions occur, preventing large valve burst and equipment structural damage, fully meet EU CE industrial heavy machinery safety standards.

7.Reserved Modular Intelligent Upgrade Expansion Interface The main electrical control cabinet reserves data communication expansion port, customers can later upgrade remote data transmission, MES system docking and automatic data cloud storage functions, realize full digital traceability of large valve batch inspection records.
