The World of Valve Assemblies
Posted in Uncategorised, on January 28, 2016 By Admin
Valve assemblies are used in a number of different industries and feature all of the various devices that are associated within the installation as well as the function of the valve within the mechanism. This term may be used in conjunction with all types of valves, including fluid flow control valves as well as internal combustion engine valves. In most cases, the valve assembly features the complete fluid control mechanism along with its casing and any necessary external sensors, connectors, and fasteners. Valve assemblies might also include any other devices that are necessary, such as shim selections, mounting adapter sets, and spare seals. Generally speaking, the valve assembly will be procured as a complete set in order to make the replacement process easier. With that said, in the case of larger valves, it may be necessary to order parts as they are needed in order to lower costs.
The Construction of Valve Assemblies
The primary component in a valve assembly is the gas or fluid control mechanism as well as its casing. While some applications are quite simple, that is not always the case. For instance, in a ball, gate, or butterfly type, the parts can be arranged in a rather complex manner and may be housed inside an external casing. In the event that the valve is automated, there will often be a second component located inside the assembly known as the actuator. The unit might be hydraulic, electric or pneumatic.
The valve assembly might also feature external controllers, such as travel limit sensors or stop/start stations. Whether or not the valve assembly includes such features will be based on the precise nature of the relevant application. Valve assemblies might also include specific types of fasteners, such as bolts and grub screws. It should also be noted that the valve assembly would also need to include any ancillary equipment that is required for installation as well as the valve's operation, including thread and flange adapters. In this case, they would typically be included as standard accessories. It should also be noted that some peripherals may need to include replacements for those parts that tend to wear out more quickly, such as seal elements, bushes, or O-rings.
