Top Pressure Valve Test Bench

Top Pressure Valve Test Bench Introduction:

• Top-pressure sealing technology: 500kN hydraulic clamping (adjustable 20–500kN) with auto-centering fixture ensures zero leakage and stable sealing for flange and butt-welded valves. Supports PN16–PN1000 valves.
• Multi-Station Testing: 4 to 8 independent test stations, support gate valve, stop valve, safety valve synchronous testing. Each station independently sets pressure (0–150MPa), time (0–300min), and medium (water/gas), boosting efficiency by 60%.
• Intelligent measurement and control system: 10” dual-language touch screen with one-button operation. PLC-controlled servo drives high-pressure plunger pump (0.1MPa resolution). Real-time pressure, leakage, and force curves. USB/Ethernet data export.
• Safety redundant design: Stainless steel test chamber (resistant to 200MPa), explosion-proof window, high-accuracy sensors (±0.3%FS), leakage detection (0.05mL/min), overpressure relief (110% of set value), compliant with EN 61010-1.

Top Pressure Valve Test Bench Features:

✅ High-pressure full compatibility

• Supports 0-150 MPa water pressure test (standard) and 0-100 MPa air pressure test (optional module), making it ideal for API 6A wellhead equipment, nuclear-grade valves, and other extreme pressure applications.
• Automatically adjusts sealing force (20–500kN) based on test pressure. For example, it applies 400kN during a 100MPa test to ensure accurate sealing.

✅ Multi-dimensional detection capability

• Performance Tests: Shell strength (1.5×), upper seal (1.1×), gas leak detection (bubble/decay method).
• Special environment testing from -196°C to 350°C (with temp control module).
• ife test: 500 pressure cycles with sealing surface wear (±0.01mm) and pressure decay (≤0.5%) monitoring.

✅ Intelligent data management

• 64G storage, records 30+ metrics. Generates detailed PDF reports compliant with ASME standards.
• Real-time SPC charts, CPK analysis, and alarm notifications for abnormal results.

International reference standards

ASME B16.34, API 598, GB/T 13927, ISO 12266-1, EN 12266-1

Product use

• Petrochemical: Detect the corrosion resistance and sealing of high-pressure ball valves and check valves (such as cryogenic valves for LNG pipelines).
• Nuclear power industry: Verify the seismic performance of safety valves and isolation valves (simulate pressure stability under earthquake conditions).
• High-pressure pipeline engineering: Re-test the shell strength of PN1000 gate valves before installation to avoid the risk of rupture under ultra-high pressure conditions.
• Valve research and development: Life test of new sealing materials (such as metal bellows) to optimize the design of high-pressure valves.
