<h2 class = 'uawtitle'>The Commonly Used Type Steam Jacketed Valves</h2><br />
<div style='font-style:italic;' class='uawbyline'>by Lisa Green</div><br /><br />
<div class='uawarticle'>Valves are type of devices that will direct, control, or regulate the fluid flow either by closing or opening partially or fully the obstruction of passageways. The examples of these fluids are slurries, fluidized solids, liquids, and gases. Technically, these are referred to as fittings but are categorized and discussed separately. The fittings are used in pipe systems to connect the sections of a pipe or a tubing and to measure the fluid flow.<br />
<br />
For a valve which is in open type, the fluids are going to flow from a higher pressure direction to a lower pressure direction. The simplest and the most ancient valves are hinged flaps that are going to drop for obstructing the running of fluids, it may be gas or liquid, in one direction and are propelled open by the opposite direction flow. The type of valves which are most commonly utilized in Houston, TX are <a href="http://www.reliantvalve.com">steam jacketed valves</a>.<br />
<br />
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.<br />
<br />
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.<br />
<br />
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.<br />
<br />
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.<br />
<br />
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.<br />
<br />
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.<br />
<br />
The valve ball is used for applications that have high pressure, severe duty, or high tolerance. Usually, this is made from titanium, hastelloy, nickel, stainless steel, stellite, or brass. The spring shifts the disc into a default position and allows the control of repositioning the disc. The trim are the internal elements of a valve.<br />
