Inspection and Testing Standards

Before and during the operation of the Pneumatic Upward Expansion Tank Bottom Valve, several inspection and testing standards must be followed to ensure the valve operates as expected and meets safety and performance regulations.

1. Visual Inspection

  • Regular visual inspections should be conducted to check for external damage, corrosion, or leakage. Ensure that the valve body, seals, and connections are intact and free from any signs of wear or damage.

2. Pressure Testing

  • Perform pressure testing to ensure the valve can handle the system's required pressure without failure. Testing should be done according to industry standards, such as ISO 5208 for pressure testing valves. The valve should be tested at 1.5 times the rated pressure to ensure structural integrity.

3. Leakage Test

  • Conduct a leakage test on the valve to check for any fluid or gas leaks at high pressure. Ensure that seals and connection points are properly sealed, and no air or fluid is escaping during operation.

4. Functionality Test

  • Perform a functional test to verify that the valve opens and closes correctly in response to pneumatic signals. The actuator response time should be measured to ensure that the valve operates within the specified time limits.


Maintenance Tips

Proper maintenance is essential for ensuring the Pneumatic Upward Expansion Tank Bottom Valve operates at peak performance and has a long service life. Below are some maintenance tips to help keep the valve in top condition.

1. Regular Cleaning

  • Clean the valve regularly to remove debris, dirt, and moisture that could interfere with the internal mechanisms. Compressed air or a soft brush should be used to clear the valve of particles that might clog or damage seals and actuators.

2. Lubrication

  • Lubricate moving parts such as the actuator and valve stem. Use high-quality lubricant recommended by the manufacturer to prevent wear and tear on these parts, which could otherwise lead to sluggish performance.

3. Seal Inspection and Replacement

  • Check seals and O-rings for signs of wear or degradation. Replace damaged seals promptly to avoid leakage. Regular seal replacement will help maintain pressure stability and ensure the long-lasting performance of the valve.

4. Check Actuator Function

  • Ensure that the pneumatic actuator is functioning correctly and receives the proper air pressure. Regularly inspect the actuator for any signs of corrosion, damage, or wear that could impact valve performance.
