Water Valve Life Durability Test Bench 100,000 Opening And Closing Cycle Test 0-60MPa Full Pressure Coverage

Water Valve Life Durability Test Bench 100,000 Opening And Closing Cycle Test 0-60MPa Full Pressure Coverage

Product Introduction

WPT-12 uses high-precision cycle control and full-condition simulation technology to achieve accurate evaluation of water valve life:

Full pressure range coverage:

• Pressure test range 0-60MPa (resolution 0.1MPa), suitable for low-pressure stop valves (1.6MPa) to high-pressure safety valves (60MPa), supporting shell strength (1.5 times nominal pressure) and sealing tests (1.1 times nominal pressure).
• Opening and closing frequency 0-30 times/minute adjustable, simulating switch loads in different scenarios such as tap water pipes and industrial pipe networks, supporting pulse and continuous cycle tests.

Intelligent measurement and control system:

• 10-inch color touch screen (Chinese and English switch) one-click setting of test parameters (number of cycles, pressure, medium temperature), PLC linkage servo motor drive opening and closing mechanism (positioning accuracy ±0.5mm), real-time collection of operating torque (resolution 0.1N・m), leakage (accuracy 0.01mL/min) and other 30+ parameters.
• Built-in 64G memory, automatically generates life cycle curve (opening and closing times - leakage relationship diagram), supports USB / Ethernet export and upper computer software analysis, and meets ISO 9001 quality traceability requirements.

Safety and reliability design:

• Stainless steel high-pressure chamber (pressure resistance 100MPa) with explosion-proof observation window, built-in double leakage sensor (accuracy 0.005mL/min), automatic unloading of overpressure (110% set value), in line with EN 61010-1 electrical safety standards.
• The intelligent fault diagnosis system identifies 5 typical faults such as seal failure and valve stem jamming in real time, with a diagnostic accuracy of >95%, and automatically generates maintenance suggestions.

Product features

All types of water valve adaptation

• Compatible with gate valves, stop valves, ball valves, butterfly valves, check valves (DN15-DN300), and can be replaced within 10 minutes through quick-release clamps (flange / threaded connection), supporting straight-through, angle and other structures.
• Strong media compatibility: clean water, sewage, oil, corrosive liquid (optional 316L stainless steel pipeline), suitable for durability testing under different working conditions.

High-precision life test

• The opening and closing times are preset from 0 to 1 million times (resolution 1 time), and the cycle positioning accuracy is ±0.2%, meeting the ISO 5208 Clause 9 "seal life test" requirements.
• The torque sensor is calibrated by CNAS (accuracy ±1%), real-time monitoring of valve switch resistance changes, and identification of early failures such as valve stem wear and seal ring aging.

Intelligent data management

• The touch screen displays the single-station SPC control chart (CPK≥1.33) in real time, and abnormal data (such as a sudden increase in leakage) is automatically marked in red and triggers an audible and visual alarm, improving quality inspection efficiency by 40%.
• Supports batch import of standard test processes such as GB/T 13927 and API 598, shortening parameter setting time by 50%, and avoiding manual operation errors.

Modular expansion capability

• Optional high temperature module (medium temperature 0-150℃) and low temperature environment chamber (-40℃) can be used to simulate valve life test under extreme temperature.
• Multi-station design (standard 2 stations, optional 4-8 stations) supports parallel testing of valves of the same type, significantly improving batch testing efficiency.

Product use

• Valve manufacturing: Full inspection/sampling inspection of water valve production line (such as 10 for household ball valves) 10,000-time life test, high-pressure seal verification of industrial gate valves), to ensure that the products shipped meet national/international standards.
• Water Engineering: Re-inspection of municipal water supply valves before installation (such as the long-term operation reliability of DN300 butterfly valves) to avoid water leakage accidents in the pipe network.
• Quality inspection and certification agencies: Provide life test reports required for CE, API, TS and other certifications, and support failure analysis such as excessive valve leakage and abnormal operating torque.
• Scientific research institutions: Life evaluation of new sealing materials (such as perfluoroether rubber), durability verification of low-torque valve design.
