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 the open types of valve, fluids will flow to the direction from the high pressure to the low pressure. The simple and most ancient valves are made hinged flaps that drops for the obstruction of fluid flow, either liquid or gas, to one direction only and it will be pushed open through its flow in the opposite direction. The steam jacketed valves type are the most common in use in the city Houston, TX.
The steam jackets are produced for keeping the body of a valve maintain its temperature. The steam, which is a very hot fluid is being circulated around it, thus, keeping the fluid that are flowing inside warm and also maintain its liquid state. The steam is being circulated in the space between jackets and vessel walls. The steam also allows the heat of being transferred through 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.
The ports are the passages from which the fluid flow will occur. Typically, valves have two ports. The handle controls the valve manually from outside the body and an actuator is the mechanism that automatically controls it. The disc is an obstruction which is movable and would restrict the flow.
The seat is the part where in it contacts the disc to form leak tight seal. It is classified to either soft seats or hard seats. The stem transmits motion from handle and controls devices to the disc. The gaskets are used for preventing fluid leakages.
Valve balls are applied into processes that have high tolerance, high pressure, or severe duty. Stellite, nickel, titanium, brass, stainless steel, and hastelloy are the common materials. Springs will shift discs to default positions and will also allow to reposition the discs. Internal parts of valve are called trims.
