Everything You Need to Know About Valve Assembly
Posted in Uncategorised, on November 25, 2021 By Admin
Valves are used in a variety of systems to regulate the flow of fluids or gases. While they have been in use for centuries, constant improvements and updates to their design have helped maintain their effectiveness. In the modern world, valves are used in the form of assemblies, essential in many industries such as waterworks, power plants, and gas pipelines. But what is a valve assembly exactly, and what are its constituent parts?
To answer these questions, here’s everything you need to know about valve assemblies.
What is a Valve Assembly?
A valve assembly can be defined as a system that centres around the valve’s mechanism, and also includes auxiliary devices such as the casing, actuation mechanisms of both electrical and non-electrical kinds, and even sensors. This system is important for regulating the flow of fluid or gas in a machine. The individual valves in this system are typically made of metal or plastic and are generally operated via a solenoid. The assembly also includes one or more check valves, which allows the fluid or gas to flow in one direction but not the other. While valve assemblies can be obtained as a complete set for configurations of larger sizes, individual parts can be purchased separately and assembled to reduce the cost of operation.
4 Major Parts of Valve Assemblies
While there are a lot of parts in a valve assembly, there are 4 major parts that you will find in almost all configurations. Here are the four typical parts included in valve assemblies.
Body
The valve body is the main part of the valve system. It houses the various components of the assembly, including the piston, valves, and springs. In essence, the valve's body allows water to flow in one direction.
Bonnet
The bonnet is the main cover of the valve body that the valve system connects to, and it is important for preventing backflow. It is fastened to the body using bolts or welding.
Trim
The smaller parts of the valve assembly that are detachable or replaceable are collectively known as Trim. It mainly includes parts such as spacers, bushings, internal springs and more.
Disks
The valve disk is the rotating part of the valve that throttles or allows the fluid or gaseous medium to flow through it.
That covers the basics of a valve assembly. There are many other parts involved in this system, but these 4 are the fundamental ones.
