The devices that are used for regulating, directing, or controlling the fluid flow through a partial or full opening or closing of obstruction of the passageways. Fluid examples are fluidized solids, gases, slurries, and liquids. These are technically considered as a fitting but discussions and categories of it are separated. A fitting is used by a pipe system for the connection of sections in the tubing or pipe and also for the measurement of fluid flows.
For open valve types, the fluid will flow into a direction coming from a high pressure down to a low pressure. The most simple and ancient valves are just hinged flaps that will drop in order to obstruct flow of the fluid, either gas or liquid, in only one direction and it is propelled open by the flow in its opposite direction. Steam jacketed valves are the most commonly used types in Houston, TX.
These steam jackets are being made in order to keep the valve body in maintaining its average temperature. The steam is a hot fluid that is circulated to keep the fluids warm which are flowing inside and to maintain also the liquid state. The steam is circulated in between the jackets and the vessel walls. It also allows heat to transfer through the vessel walls.
The valves must undergo a leak and pressure testing after and before the jacketing process. Considerations are very important in this process. These are the types and locations of the heated medium connections, flange size, materials, full coverage or full coverage, and additional coverage of heat to specific areas or bonnet jacket.
Valves have eleven components and the usual parts are body and bonnet. The body is the outer part which contains all the internal parts or the trim. These are usually plastic or metallic. Bronze, cast iron, alloy steels, brass, gunmetal, steel, and stainless steel are the most common materials.
The bonnet will serve as a covering to a body. It is usually screwed or may be bolted into a body semi permanently. In the manufacturing process, the internal components are placed inside its body and the bonnet is affixed to it to hold all things in place inside. A bonnet may be taken out when maintaining the inside parts.
A port is the passage where flow of the fluids will occur. Valves typically have only 2 ports. A handle manually controls the valve from outside of its body while an actuator automatically controls it. A disc is an obstruction type that is movable and will restrict flow.
The seat is a part that will contact the disc in forming the leak tight seal. This is classified into hard seats or soft seats. The stem will transmit the motion coming from the handle or will control the device into a disc. Gaskets are used to prevent any leakages of fluids.
A valve ball will be used in applications which have severe duty, high tolerance, or high pressure. It is usually made from hastelloy, stainless steel, brass, titanium, nickel, or stellite. A spring will shift a disc into its default position and will allow to control disc repositioning. Trims are internal components of valve.
