DN300 Compact Horizontal Hydraulic Top Pressure Valve Test Bench

Adopting an adjustable opening span structure, this DN300 Compact Horizontal Hydraulic Top Pressure Valve Test Bench is widely compatible with gate valves, ball valves, butterfly valves, and other mainstream straight-through industrial valves. It can complete shell strength pressure test and seat tightness pressure holding leakage inspection fully in accordance with GB/T13927-2022 and API 598 international valve pressure testing specifications. Equipped with an automatic constant pressure holding system and multi-group precision pressure gauges, it supports water-air dual testing media switching and built-in safety interlock protection devices. 

The bench balances flexible adjustability and structural stability perfectly, solving the common pain points of general-purpose test benches such as large floor occupation and poor versatility. The compact integrated layout greatly reduces workshop space occupancy; the overall welded bed frame is solid and shock-resistant, suitable for daily batch quality inspection and maintenance re-inspection work of medium- and small-sized valve factories. 

Basic parameters: Max applicable caliber DN300, total weight 2.5 tons, overall dimension 26758901720mm; power and maximum test pressure can be customized on demand. We can provide CE certification, multi-language operation panels, and export voltage adaptation for overseas small and medium valve manufacturers. Contact our technical team to obtain a detailed datasheet and a preferential quotation within 24 working hours.

Seven Core Differentiated Advantages

1.Ultra compact Integrated Layout, Small Floor Space The biggest advantage of the Compact Horizontal Hydraulic Top Pressure Valve Test Bench: optimized miniaturized overall structural design, far smaller footprint than conventional horizontal test benches, perfectly suited for small valve workshops with limited plant area.

2.Continuously Adjustable Clamping Stroke, Wide Valve Compatibility: The horizontal sliding beam realizes stepless adjustment of the clamping distance, adapts to various length specifications of DN50~DN300 gate valves, ball valves, butterfly valves, stop valves, one machine covers most commonly used small and medium flange valve types.

3.Dual Water & Air Medium Independent Pressure Circulation System Separate water filling pipeline and air pressurization pipeline are arranged independently; water is used for shell strength test, compressed air for tightness leakage detection. PLC constant pressure control system automatically compensates pressure loss during the holding period, pressure fluctuation ≤±1%.

4.Stable Axial Synchronous Hydraulic Jacking Clamping: Double hydraulic cylinders push the pressing plate synchronously to apply even axial force on valve flanges; no unilateral deflection or eccentric stress; clamping force can be adjusted according to the valve wall thickness to avoid flange deformation and sealing surface damage.

5.Integrated Hydraulic Station Inside Cabinet, Clean & Neat Workshop Hydraulic pump station, pipeline assembly, and valve block are all concealed inside the control cabinet, no exposed messy pipelines outside, reducing oil pollution and noise, and making it easy for daily cleaning and maintenance.

6.Multi-layer Built-in Safety Interlock Protection Mechanism Equipped with hydraulic clamping overpressure relief, test pressure over-limit cut-off, and emergency stop power-off protection, three-fold safety interlock. Once abnormal conditions occur, all power output will be cut off instantly, complying with EU CE industrial machinery safety standards.

7.Reserved Digital Intelligent Upgrade Expansion Port The main electrical cabinet reserves a communication expansion interface; customers can later retrofit a touch screen automatic testing program, pressure curve recording, electronic inspection report export, and MES system docking functions to realize digital whole-process traceability of inspection data.
