Description
Precision Testing for Industrial Valve Integrity and Performance
The YOUJI JWZ Type Hydraulic Valve Test Stand is an advanced testing system engineered for comprehensive performance evaluation of flanged valves. Integrating mechanical, hydraulic, and electronic control systems, this test bench provides reliable and efficient strength, sealing, and leakage tests. Developed in strict accordance with international standards like GB/T 13927 and API 598, and holding national patent (ZL2016 1 0240324.1), the JWZ series is the ideal valve testing equipment for manufacturers and service providers in critical industries.
Key Features
- Patented Claw Clamping System: Utilizes a hydraulic claw mechanism to grip the valve flange from the back. This method ensures uniform force distribution and eliminates external stress on the valve body, guaranteeing that test results are accurate and unaffected by the clamping process.
- Compliance with International Standards: Designed and manufactured to meet the rigorous requirements of GB/T 13927-2022, API 598-2009, and other key industry standards, ensuring your testing procedures are certified and reliable.
- 90° Tilting for Air Seal Testing: The work table can be tilted 90 degrees, providing an optimal setup for performing air (pneumatic) seal tests with enhanced visibility and accuracy.
- Integrated Hydraulic & Control System: Features a self-contained system with high and low-pressure water pumps, media circulation, and a choice of control modes (PLC computerized, push-button). The automated process significantly improves work efficiency and reduces manual labor.
- Advanced Safety Protection: Equipped with a hydraulic automatic unloading system and pressure interlocks. The system prevents operation under high residual pressure, ensuring operator safety and extending the equipment’s service life.
- Optional Computerized Data Management: Can be configured with a PC-based data acquisition and management system to record, save, and print detailed test reports, providing full traceability for quality control.
