Types of PVC valve

  1. Ball valves: These valves use a spherical closure unit (a ball) to control the flow. When the valve is open, the ball’s hole aligns with the pipe, allowing fluid to pass through. When closed, the ball is rotated to block the flow.
  2. Check valves: Check valves allow flow in one direction only and prevent backflow.
    They are commonly used to maintain fluid flow in one direction and prevent reverse flow, which can be critical in preventing damage to pumps and other equipment.
  3. Swing Type Non Return Valves
  4. Double Union Non Return Valves
  5. Single Union Non Return Valves
  6. Butterfly valves:
    Butterfly valves use a disc mounted on a rotating shaft to control flow.
    When the valve is open, the disc is parallel to the flow, allowing for minimal obstruction.
    When closed, the disc is rotated perpendicular to the flow, blocking it completely.
