Description
The YOUJI JLT Type Vertical Hydraulic Valve Test Bench is a new-generation, patented testing solution (Patent No. ZL2016 1 0240324.1) engineered for comprehensive valve performance evaluation. It is expertly designed to conduct precise pressure strength and sealing tests on a wide variety of flanged, welded, and threaded valves, including gate, globe, ball, and check valves.
This system is built to meet the rigorous demands of industries such as Oil & Gas, Nuclear Power, and Chemical Processing. By fully complying with international and national standards like API 598-2009, GB/T 13927-2022, and JB/T14310-2022, the JLT test bench provides verifiable, accurate, and reliable testing results for both valve manufacturers and end-users.
Key Features
- Versatile Clamping & Sealing: The system uniquely combines a hydraulic claw clamping mechanism with a top-down hydraulic pressing function. This dual-action design securely tests various valve types without inducing external stress that could affect test accuracy.
- Advanced Safety Interlocks: Operator safety is paramount. During pressure-holding cycles, all function buttons are automatically disabled if high pressure is detected in the valve cavity, preventing unsafe operations until the system is fully depressurized.
- Efficient Hydraulic System with Automatic Unloading: Features an intelligent hydraulic system that automatically switches between high-pressure and unloaded states. This significantly reduces oil temperature, extends the service life of the equipment, and conserves energy.
- User-Friendly Design: The upper crossbeam is designed to be pushed back and rotated 90 degrees, greatly simplifying the loading and unloading of heavy or awkwardly shaped valves and improving operational efficiency.
- Multi-Medium Testing Capability: Equipped with integrated high and low-pressure pumps, the system supports water, air, or kerosene as test media. A built-in reservoir allows for the recycling and storage of the test medium.
- Optional Data Management System: The unit can be upgraded with a PC-based data acquisition and management system to enable digital recording, analysis, and reporting of test results.
