<p><strong>Gate valve</strong></p><p>The gate valve is designed for fully open or fully closed operation. Because they run slowly, they can prevent fluid hammering that is harmful to the piping system. The pressure loss through the gate valve is very small. In the fully closed position, the gate valve provides a positive seal under pressure. However, at very low pressures, namely 5 psi, this type of valve will not treat a slight leak as an abnormality.</p><p> </p><p><strong>Ball valve</strong></p><p>The ball valve is also designed to fully open or fully close in any liquid containing particles that may scratch the sphere. Many people use them successfully to throttle clean water. The pressure of the ball valve is reduced, the opening and closing is rapid, the operation is simple, and there is no trouble. With the development of Teflon seals, ball valves are becoming more and more popular. Opening or closing the ball valve too quickly can cause fluid hammer.</p><p> </p><p><strong>Butterfly valve</strong></p><p>Butterfly valves, such as ball valves, rotate in a 1/4 turn. They are usually used to handle large flows of gases or liquids, including slurries, but should not be used for throttling for a long time. They are also very compact compared to flanged gate valves and ball valves.</p><p> </p><p><strong>Shut-off valve</strong></p><p>Globe valves, like all-valve designs, have both advantages and disadvantages. Like doors, they close slowly to prevent fluid hammering. You can throttle the flow and they will not leak at low pressure when they are closed. Flow and pressure control valves and hose bibs usually use spherical patterns. The disadvantage of this design is that the "Z" type can restrict flow more than gate valves, ball valves or butterfly valves. All psi ratings apply to water, oil or gas. Steam is usually derated by one-half. (250 psi water or 125 psi steam).</p><p> </p><p><strong>Stopcock</strong></p><p>Like gate valves, plug valves have unobstructed flow, but they only need to be turned 90 degrees to open it. It also requires very little headroom. Since there is no thread, the valve stem has minimal corrosion. Almost all stopcock valves nowadays are equipped with an elastomer-coated stopcock, which will leak tightly. However, the size of the plug valve is much larger than that of the ball valve, which is very suitable for sewage treatment plants.</p><p><br></p><p>If you are looking for a professional <a href="https://www.zjxhvalves.com/" rel="noopener noreferrer" target="_blank"><strong><a href="https://www.zjxhvalves.com/" target="_blank">valve manufacturer</a></strong></a>, Xinhong Valve valve manufacturer is a good choice for you.
