Kugelrückschlagventile
Kugelrückschlagventile, also known as ball check valves, are a type of non-return valve that utilizes a spherical ball as the sealing element. Their primary function is to allow fluid flow in one direction only, preventing backflow. The ball is typically made of metal, plastic, or rubber and is seated within a corresponding conical or spherical housing. When fluid pressure is applied in the forward direction, it lifts the ball off its seat, allowing flow. As the pressure drops or reverses, the ball is forced back onto its seat by gravity, the fluid's back pressure, or a light spring, thereby sealing the valve and stopping reverse flow. Kugelrückschlagventile are known for their simple design and robustness. They are often used in applications where high reliability and minimal maintenance are required. Their compact size and ability to handle suspended solids in certain designs make them versatile. Common applications include plumbing systems, industrial pipelines, pumps, and various fluid handling equipment. The specific material of the ball and seat is chosen based on the fluid properties and operating temperature to ensure compatibility and effective sealing.
