Installation Instructions

  1. Preparation: Ensure the pipeline is clean and free from debris. Verify flange compatibility.

  2. Mounting: Align the valve with the pipeline flanges. Use appropriate gaskets and bolts to secure the valve. Tighten bolts in a criss-cross pattern for even pressure.

  3. Pneumatic Connection: Connect the pneumatic actuator to the air supply according to the manufacturer's specifications.

  4. Inspection: Test the actuator to ensure smooth operation and check for any obstructions.

Operation Guidelines

  • Opening/Closing: Use the control system to operate the pneumatic actuator for opening and closing the valve.
  • Flow Control: Ensure the valve is fully open or closed to prevent partial obstruction.

Maintenance

  • Regular Inspection: Check for signs of wear or damage. Ensure the actuator and valve components are in good condition.
  • Seal Maintenance: Inspect seals periodically and replace if necessary to maintain tight sealing.
  • Cleaning: Keep the valve and actuator clean and free from external contaminants.

Safety Precautions

  • Always disconnect the air supply before performing maintenance.
  • Use appropriate personal protective equipment (PPE) during installation and maintenance.
  • Ensure all personnel are trained in valve operation and safety protocols.

Product Description

Advantages:

1. Fluid resistance is small.

2. Opening and closing require less external force.

3. The flow direction of the medium is unrestricted.

4. When fully open, the sealing surface is less eroded by the working medium than the globe valve.

5. Shape is relatively simple and its casting technology is good.
