Understanding Control Valve Assemblies
Posted in Uncategorised, on November 09, 2016 By Admin
The term “valve assemblies” refers to a complete valve mechanism. In other words, this term references the entire mechanism, which consists of all peripheral devices that relate directly or physically to both the valve’s installation and functionality. The term is something that can be applied to virtually all types of valves, including fluid flow control valves, internal combustion engine valves, and gas valves.
Typically, valve assemblies include a fluid control mechanism, as well as a mechanical or electrical actuation mechanism, casing, and other components, such as fasteners, connectors, and external sensors. There are occasions when a valve assembly is supplied with ancillary devices. If applicable, this would consist of shim selections, spare seals, and mounting adapter sets.
Valve automation is extremely beneficial for a variety of industrial applications. For that reason, these valves are commonly part of refineries, power plants, nuclear processes, mining processes, pipelines, and wastewater treatment plants. Valve actuators play a vital role in automating process controls.
With valve assemblies, it is possible to start, stop, and throttle the flow of gas or fluid going through the system. In most cases, these assemblies are purchased as a whole. Not only does this make the process of replacement easier, it helps cut down on cost. Typically, the mechanism that controls gas or fluid is the major component of a valve assembly, although the casing is also relevant when included. However, other entities may exist for certain applications.
For manually actuated valve assemblies, the mechanism is often a key part of the main body. Specific to valve automation, there is usually an actuator, whether a hydraulic or pneumatic unit, electric motor, or a solenoid. For some applications, a valve assembly also has external controllers, including travel limit sensors, as well as start and stop stations. Whether you need a manual or automated mechanism, it is essential to identify the top-rated valve assembly suppliers before making your purchase.
