DYFJ-NJ300 Valve Life Torque Test Bench

Key Performance
1. Versatile Application:
The DYFJ-NJ300 is specifically designed to test flange-connected valves, making it suitable for a wide range of valve types, such as ball valves, gate valves, and globe valves.

2. Hydraulic Clamping System:
The test bench utilizes hydraulic claws to securely clamp the flange backside, ensuring a tight seal on the valve ends without applying external force to the valve body.

3. 90-Degree Rotation Capability:
The DYFJ-NJ300 features a 90-degree rotation function (optional dual-end rotation), allowing the valve to be flipped for thorough sealing performance testing.

4. Flexible Testing Media:
The test bench 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 using pipeline control valves, providing flexibility for different testing requirements.

5. Dual-Pump Pressure System:
Equipped with a low-pressure rapid water pump and a high-pressure slow boost pump, the DYFJ-NJ300 ensures precise pressure control. Once the target test pressure is achieved, the system automatically initiates the pressure-holding timer, ensuring consistent and accurate test conditions.

6. Zero-Pressure Safety Protection:
Safety is a top priority with the DYFJ-NJ300. 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. Integrated Valve Testing System:
The test bench is equipped with a dedicated valve testing system, including a PLC data acquisition system, an automatic testing system, and a torque testing system. These integrated systems provide comprehensive data collection and analysis, ensuring precise and repeatable test results.

8. Customizable Non-Standard Configurations:
The DYFJ-NJ300 can be customized to meet specific non-standard requirements, offering flexibility for unique testing needs. This adaptability makes it an ideal choice for specialized applications and ensures that it can be tailored to suit a wide range of valve testing scenarios.
