All about industrial valves

A sight glass fitting enables visual inspection of the interior of containers and pipelines, as well as level monitoring. There are various types, including container sight glasses and flow sight glasses, each with different mounting methods and areas of application. These fittings are used worldwide in a range of industrial applications to ensure safe and efficient process monitoring.

Detailed answer 

Industrial valves are mechanical components used to control and regulate the flow and pressure of fluids in process systems. They are primarily used in piping systems and include a variety of types such as shut-off valves, ball valves, and sight glass fittings. Some operate automatically, others manually or via actuation systems. A typical valve consists of a housing, internal components, and an actuation mechanism. The housing connects the valve to the system and withstands pressure loads, while the shut-off element regulates the flow.

Detailed answer

A gate valve is a type of valve that completely opens or closes the flow in a pipeline. It uses a wedge-shaped shut-off element and is designed to operate only in fully open or fully closed positions, as partial opening may lead to increased wear. Variants include models with internal or external stems, with the external stem offering better suitability for aggressive media. Gate valves provide bidirectional sealing and are available for a range of pressure classes.

Detailed answer

A butterfly valve is a compact valve type that opens or closes the flow of media with a 90° rotation of the disc. Its simple and compact design offers significant cost advantages. It is primarily used for on/off operation and is only conditionally suitable for throttling. However, its design also introduces disadvantages, such as flow resistance and a risk of damage when handling media containing solids.

Detailed answer

A ball valve is a fitting that opens or closes the flow of liquids or gases in pipelines with a 90° rotation of a ball in the housing. It allows for quick and easy shut-off and is particularly suitable for use with critical media such as flammable or toxic substances. Ball valves are available in different designs, which vary by ball bore, bearing, and sealing.

Detailed answer

A chick valve is a fitting for flow regulation, in which a conical shut-off body, the chick, opens or closes the flow by rotation.

Detailed answer

A "Double Block & Bleed" fitting consists of two shut-off valves ("Double Block") between which there is a valve for draining the intermediate space ("Bleed"). Such a fitting is usually used where the separation of two systems must be particularly reliable. Whether it is to prevent the mixing of process media, for maintenance work, or to avoid contamination, etc.
