Hydraulic Valve Test Bench for DN15-DN100 Flange Valve Pressure Testing

This DN100 hydraulic jaw gripper clamping valve test bench adopts a horizontal horizontal jaw quick clamping design, eliminating the time-consuming disassembly of traditional vertical test benches, realizing fast loading and unloading of flanged straight-through valves within 30 seconds, greatly boosting daily inspection throughput for small and medium valve workshops. Equipped with 8 groups of independent precision pressure gauges and multi-channel independent pressure regulating valves, it can simultaneously conduct shell strength hydrostatic testing and two-way seat tightness leakage testing, supporting high, medium and low pressure segmented pressure holding and automatic pressure compensation functions. 

The built-in closed circulating water tank realizes recycling of test medium, reduces water resource waste and workshop cleaning workload; a centralized PLC button control panel integrates all test operation logic, with overload pressure relief, power failure pressure maintaining and emergency stop triple safety interlock protection to avoid misoperation damage to valves and equipment. The overall compact layout saves factory floor space, specially customized for DN15~DN100 flanged ball valves, gate valves, globe valves and check valves, widely matching small-scale valve manufacturing workshops, petrochemical maintenance stations, municipal water supply and drainage engineering inspection rooms and power plant auxiliary valve testing posts.

Supporting offline test data manual recording and optional touch screen digital data acquisition upgrade, with export CE safety modification and multi-language operation panel available for overseas valve processing factories. It realizes all-in-one testing of valve shell strength, upstream and downstream bidirectional sealing tightness, meets third-party inspection institution certification test requirements, and is the cost-effective core inspection equipment for medium- and small-scale valve mass production lines. If you need standardized horizontal jaw clamping valve pressure testing equipment with full standard certification, contact our technical team to receive complete parameter sheets and a formal framework quotation within 24 working hours.

Seven Core Competitive Advantages

1.Horizontal Jaw Quick Clamping Ergonomic Structure Horizontal side jaw gripper clamping mode, no need to lift heavy valves vertically; operators only push the valve body horizontally into the clamping station; the adjustable jaw stroke adapts to different flange thicknesses of DN15–DN100 valves; single valve clamping time is shortened by 60% compared with vertical four-column test benches; suitable for continuous batch inspection of small and medium-sized valves; the core clamping structure of DN100 Hydraulic Jaw Gripper Clamping Valve Test Bench.

2.Multi-channel Independent Pressure Separate Control System: 8 precision pressure gauges matched with independent pressure regulating valves, separately control shell test pressure, upstream sealing test pressure, and downstream sealing test pressure, realizing segmented high/medium/low pressure holding without mutual pressure interference, fully meeting API 598 multi-stage pressure inspection clauses; stable pressure control is the core performance advantage of the DN100 Hydraulic Jaw Gripper Clamping Valve Test Bench.

3.Integrated Closed-loop Medium Circulation Storage Tank Bottom integrated water storage and circulation pipeline, automatic recovery of test water after each test cycle, zero medium spillage in the inspection workshop, reduce daily water consumption and manual floor cleaning work, adapt to long-shift continuous workshop production environment.

4.Triple Interlock Industrial Safety Protection Mechanism Built-in hydraulic overload relief valve, power-off automatic pressure-maintaining valve, and physical emergency stop button three-layer safety protection; automatically cut off pressure output when overpressure occurs, preventing valve burst damage caused by misoperation; comply with EU CE industrial machinery safety specifications.

5.Compact Floor-saving Integrated Cabinet Layout All hydraulic power unit, electrical control cabinet, medium storage tank, and clamping frame are integrated into one whole machine, occupying less than 3 square meters of workshop area, perfectly matching small independent inspection rooms, maintenance stations, and small-batch valve production workshops with limited space.

6.Full Global Standard Compliance Certification: Factory production strictly follows ISO 9001 quality system, test performance fully meets domestic GB industrial valve test standards and American API 598 inspection specifications, and can provide complete factory inspection reports, calibration data sheets, and certification supporting documents for third-party testing institutions and overseas EPC project acceptance.

7.Modular Digital Upgrade, Expandable Configuration, Retained Reserved Data Communication Interface on the Control System, Can Be Later Upgraded to Touch Screen PLC Automatic Test Cycle, Pressure Curve Recording, Electronic Test Report Export Function, Realize Digital Traceability of Inspection Data, Seamless Docking with Factory MES Intelligent Production Management System.
