DYFJ-H High Accuracy Butterfly Valve Test Bench

Key Features
1. Versatile Testing Applications
The DYFJ-H is suitable for conducting both sealing performance and shell strength tests on butterfly valves with flange connections and wafer-style designs.

2. Flexible Configuration Options
The test bench is available in single-station and dual-station configurations, allowing users to select the setup that best suits their production or testing requirements.

3. Hydraulic Clamping System
Equipped with hydraulic cylinders, the DYFJ-H applies pressure to the valve end faces without exerting external forces on the valve body. This ensures accurate and distortion-free testing, preserving the integrity of the valve during the evaluation process.

4. Dual Media Testing Capability
The test bench supports both water and gas as testing media. The water-based system features a closed-loop design, enabling the recycling of water for cost-effective and environmentally friendly operations.

5. Advanced Pressure Control System
The DYFJ-H integrates a low-pressure rapid-fill pump and a high-pressure slow-boost pump to achieve precise pressure levels. Once the target pressure is reached, the system automatically initiates a pressure-holding timer, ensuring consistent and repeatable test conditions.

6. Zero-Pressure Safety Mechanism
Safety is a top priority with the DYFJ-H. The system includes a zero-pressure safety protection feature, which ensures that the clamping mechanism can only be released and the valve removed when the internal pressure of the tested valve is completely relieved.

7. Customizable Add-Ons
Customers can opt for additional features to enhance functionality, such as safety guard doors and specialized valve testing systems. These include PLC-based data acquisition systems and automated testing modules, which streamline the testing process and improve data accuracy.

8. Customization for Non-Standard Requirements
The DYFJ-H can be tailored to meet specific non-standard requirements, ensuring that it aligns perfectly with unique testing needs. This customization capability underscores its adaptability and commitment to customer satisfaction.
