Product Features

Efficient Flow Passage: Designed to prevent backflow in the line with minimal pressure drop. The disc swings into the open position as media flows through the valve, and back pressure holds it in the closed position.
Versatile Installation: Suitable for installation in both horizontal and vertical lines, with proper installation based on the flow direction marked on the body.
Customizable Accessories: A variety of accessories, such as bypasses, locking devices, counterweights, and others, are available to meet specific customer requirements.
