A valve is used to shut off or control liquids or gases. By using valves, the flow rates in a pipeline can be precisely metered and safely sealed off from the environment. In addition, there are safety valves which, in contrast, allow large mass flows in order to quickly compensate for impermissible pressure conditions, for example in a container. In principle, a closure part of valves is moved approximately parallel to the direction of flow of the fluid. The flow is interrupted by pressing the sealing surface of the closure part against a suitably shaped opening, the valve or seal seat. The closure parts can be plates, cones, balls or needles, for example. The various types of valves are differentiated according to design and pressure loss, type of actuation, task or even design of the shut-off body. The Krones.shop offers a high-quality range of different components and valves. These include, for example, directional control valves, solenoid valves, and check valves.
