Details
- A Universal Hydraulic Test Rig for Valves is a versatile and essential tool designed to test and validate various types of valves under controlled conditions. These rigs are commonly used in industries such as oil and gas, steel plant and manufacturing to ensure the reliability and safety of valves before they are installed in real-world applications. The rig's adaptability and precision make it an indispensable tool for quality assurance, operational testing, and endurance evaluation, reducing downtime and ensuring compliance with industry standards. Here are key elements typically included in the content for such a system:
The machine is capable to test the different kind of valve i.e. Servo valve, Proportional valve, DC valve , Pressure reducing valve, Pressure relief valve - Major test to be performed:
- Hydraulic valves testing
- Hysteresis test
- Flow vs command
- Pressure vs command
- Command vs spool feedback
- Step response test.
- Null position checking
- Null biased test.
- Fail safe condition test
