Industry Common Pain Points & Targeted Solutions

3.1 Core Existing Problems in Small & Medium Caliber Valve Testing

There are two widespread industry pain points in the current production and inspection of small and medium-sized valves: 

First, single-station efficiency bottleneck: Most small valve test benches adopt single-station structure, with serial workflow of part replacement, clamping, pressure holding and unloading. The long idle waiting time leads to low daily inspection output per capita, which cannot match the delivery rhythm of mass production lines, and often delays delivery due to insufficient quality inspection capacity in peak seasons. 

Second, clamping force interferes with test accuracy: Ordinary pressing structure has concentrated stress, and small-caliber thin-wall valves are prone to micro-deformation due to excessive clamping force, resulting in sealing surface dislocation and false judgment of qualified products; meanwhile, tooling loading and unloading is cumbersome, and multi-specification switching adjustment takes a long time, with poor flexible production adaptability.

3.2 Targeted Solutions of This Equipment

To thoroughly resolve the two major bottlenecks restricting the efficiency and precision of valve factory inspection, the Dual Station Integrated Vertical Hydraulic Axial Press Valve Test Bench carries out targeted structural optimization and functional upgrading aiming at the above industry pain points: For efficiency pain point: Adopt left and right dual-station independent parallel design. Two workstations can be clamped simultaneously and tested independently. While one station is in pressure holding process, the other station can complete part replacement and loading/unloading, with no idle waiting time. Batch inspection efficiency is increased by more than 80% compared with single-station equipment, perfectly matching the mass production quality inspection demand of small and medium-sized valves. 

For accuracy and loading/unloading pain point: Adopt jaw positioning + cylinder pressing dual composite clamping with accurate positioning and uniform jacking force, which has minimal extra external force on the valve body and avoids clamping deformation of thin-wall valves. Matched with 90° rotation function of tooling, the operation space for valve loading and unloading is larger, assembly and disassembly are convenient, and multi-specification switching adjustment is fast, greatly shortening auxiliary working hours.

Seven Core Differentiated Advantages

1.Dual-station Parallel Operation, Batch Inspection Efficiency Doubled The core competitive advantage of Dual Station Integrated Vertical Hydraulic Axial Press Valve Test Bench: two sets of independent hydraulic and control systems for left and right stations, supporting simultaneous testing of two valves of different types and calibers, no mutual interference, which effectively solves the problem of low efficiency of single-station serial operation.

2.Dual Composite Clamping Structure, Minimal External Force Impact on Valves Dual clamping mode of jaw positioning and hydraulic cylinder axial pressing: the jaw realizes accurate centering and fixing, and the hydraulic cylinder provides uniform axial jacking force. The force is evenly distributed on the end face of the valve, which will not cause extrusion deformation of thin-wall small valves, and truly restores the stress state of the valve in actual pipeline operation.

3.90° Rotatable Tooling, Greatly Improving Loading & Unloading Efficiency The clamping tooling is designed with 90° manual rotation function. When loading and unloading workpieces, the tooling can be rotated to the side facing the operator, which is more convenient for hoisting and tightening operations, especially for small valves with frequent replacement, which significantly reduces the auxiliary time for loading and unloading.

4.One Machine Completes Three Major Tests with Strong Universality It can independently complete shell strength test, back seat test and air tightness test, and is compatible with screwed, welded and flanged valves. One equipment covers the full-item factory inspection of gate valves, globe valves, check valves and ball valves, eliminating the need for multiple testing equipment and saving workshop space and procurement cost.

5.Fully Compliant with Domestic and International Testing Standards All design and test indicators strictly comply with GB/T13927-2022 and API 598 valve testing specifications. The pressure control accuracy and pressure holding time meet the standard requirements. The test results are authoritative and credible, which can be used for factory delivery inspection and third-party quality certification support.

6.Integrated Vertical Layout, Small Occupation & Easy Installation All hydraulic station, control system and two test stations are integrated on one base frame. No on-site complicated assembly is required, and it can be put into use after connecting power supply and water source. The overall floor area is small, which is suitable for workshop transformation and limited-space production line layout.

7.Modular Optional Configuration, Flexible Customization on Demand Three optional upgrade modules are reserved: intelligent data management system (pressure curve recording, report export), hydraulic air cooling system (suitable for long-time continuous operation), safety protection device; test caliber, pressure grade and station spacing can also be customized according to actual production needs.
