Benefits of Process Butterfly Valves

Maintaining production requires the use of industrial machines and processes. People rely on machines for production, refining, filtering, and circulation needs. It is expected that systems are able to perform the operations that meet our needs. Many of these operations that systems perform for those purposes require control and manipulation of a gas or liquid as it flows through a pipe system. Valves are generally utilized in instances where flow needs to be stopped, started, or redirected. Sometimes, process butterfly valves are necessary options for control.

Process butterfly valves are utilized to direct a gas or liquid to a certain portion of a pipeline. The valves works to control the substance by rotating a disc, which is used to either stop a substance from entering, direct the substances in a different direction, or only allow a portion of a substance to travel through. When process butterfly valves have their discs positioned perpendicular to the pipe, they create a strong seal. The gas and liquids flowing through a system are not able to penetrate the seal, and flow is restrained. Process butterfly valves have discs that are connected to shafts, which then rotate to control the position of the disc. When process butterfly valves are in the open position, the rod moves the disc so that it is parallel to the pipeline. Liquid or gas is then permitted to pass through on either side of the disc. Regardless of how far process butterfly valves are opened, the flow of a gas or liquid will still be somewhat restricted when it travels through. This restriction is a result of the disc still being located within the path of flow for the substance.

Process butterfly valves are in the family of quarter-turn valves, which means that it requires a quarter of a turn to move the valve from the completely open position to the completely closed position. In addition to controlling the flow of a liquid or gas through a system, process butterfly valves can also be utilized to release some of the excess pressure that might build up through the normal operation procedures in a system. The valve can be utilized to release certain amounts of a substance to an area where the pressure can be released, so that it does not continue to build up in the system and lead to negative results.

Process butterfly valves can be manipulated and controlled by different types of actuators. The most common actuators utilized in these conditions include electric, hydraulic, and pneumatic actuators. These actuators are powered by either electricity, liquid pressure, or gas pressure, respectively. Some of the actuators, such as those powered by liquid or gas, require pumping systems in order to power the actuator and operate valve movement. Electric actuators do not require pumping systems, but they also are unable to provide the amount of power and pressure as these other types of actuators can. Each company needs to weigh the benefits of different options before deciding which type of system components to implement.
