Butterfly valves are designed to regulate gas or liquid flow through a disk, the main closing mechanism. This type of valve allows flow though one direction but does not have pockets to contain the liquid when the valve is closed. The presence of the disk within the flow also creates a certain pressure drop. This…
A butterfly valve is typically used for flow regulation in piping systems. In several industrial facilities, butterfly valves are equipped with actuators. An actuator is specialized mechanical device mainly used to start and stop valve systems, thus creating greater control of the gas or liquid flow. When butterfly valve actuators receive energy, they convert it…
A butterfly valve is a valve classification that mainly regulates the flow of different substances though a circular pipe or a tube. Various industries, especially those that maintain water systems, require the use of butterfly valves. Butterfly valves can accommodate the flow of not only water but also air, gas and steam materials. Some of…
A butterfly valve plays an important role in controlling the flow of materials like liquid, air, gas and steam through a pipe or tube. This valve’s main components include the body, seat, stem, actuator and disk. The circular disk of a butterfly valve is attached to a shaft that turns the disk to permit flow in…
Check valves are special mechanical devices that regulate the flow of liquid or gas in one direction, to avoid piping system damage. A check valve usually has two openings called ports, and is made of various sizes and materials. One of the most common materials is carbon steel. A carbon steel check valve can be used…
Check valves are also called one-way valves because they allow fluid flow in one direction only. To achieve a one-way flow, check valves are manufactured following different design approaches. A number of this valve types are either designed to have a ball that pushes against a spring or a flapper that is anchored to one…
