Operation Principle
The valve disc slides along the vertical centerline of the valve body. When medium flows in the designated direction, the valve disc opens via medium pressure. When flow stops or reverses, the disc automatically closes against the valve seat, preventing backflow. The straight-through design minimizes flow resistance while maintaining reliable sealing.

Installation Guidelines
- Ensure pipes are clean before installation
- Align valve arrow direction with fluid flow
- Maintain cleanliness during installation (valves are pre-degreased)
- Open all valves after pipeline construction to remove debris
- Operate valves slowly during initial use
- Replace worn components (disc, seat, stem) promptly
