DYFJ-A Horizontal Clamping Valve Test Bench

Key Performance
1. Wide Applicability:
The DYFJ-A is specifically designed to test a variety of flange-connected valves, such as ball valves, gate valves, globe valves, check valves, and control valves.

2. Hydraulic Clamping System:
The test bench utilizes a hydraulic claw system to seal the valve's end face by clamping the back of the flange. This method ensures that no external force is applied to the valve being tested, preserving its structural integrity and providing accurate test results.

3. 90-Degree Rotation Capability:
The bench is equipped with a 90-degree rotation feature (optional dual-end rotation), allowing valves to be flipped for thorough sealing performance tests.

4. Versatile Testing Media:
The DYFJ-A supports both water and gas as testing media. The water used in testing can be recycled, making the system environmentally friendly and cost-effective. The media can be easily switched via pipeline control valves, ensuring seamless operation.

5. Dual-Pump Pressure System:
The test bench is equipped with a low-pressure rapid water pump and a high-pressure slow-increase water pump. This dual-pump system ensures precise pressure control, automatically entering the pressure-holding phase once the target test pressure is achieved.

6. Zero-Pressure Safety Protection:
Safety is a top priority with the DYFJ-A. The system includes a zero-pressure safety protection feature, which ensures that the hydraulic claws can only be released and the valve removed when there is no pressure inside the valve cavity.

7. Customizable Options:
Customers can opt for additional features, including dual-end 90-degree rotation, safety protection doors, and specialized valve detection systems such as PLC data acquisition and automated testing systems.

8. Custom Non-Standard Designs:
The DYFJ-A can be customized to meet non-standard specifications, ensuring that it can adapt to unique testing needs and specialized valve designs.
