Regardless of the size and niche of your processing application system, there is an extensive range of control valves that can easily suit all your industrial applications. But to find the best fit valve for your needs, you should compare a few of them before determining the type that works best for your application system. And if you’re not an expert on these valves, the first thing to do is learn more about process control valves from professional avenues.
Visiting any process control valve center or firm online or physically will help you learn the different processes involved with these valves and the crucial requirements most industrial plants use to measure and analyze the properties of liquids and gases in various applications. For example, it could be a process that handles ultrapure water in power industries or electronic companies. Next, let’s explore this guide to help you comprehensively analyze the available types of these valves, how they work, and even the essential things to look into when buying them.
The Common and Popular Types of Control Valves Available in the Market
While every control valve helps a processing system application control and regulates temperature and pressure changes and levels of the relevant downstream content, you will easily find the best fit if you know the different types as follows.
Unlike their counterparts, gate process control valves are for on and off and sometimes non-throttling services. And they are the best fit for system applications that require a straight-line flow of content, especially if you also want to restrict the direction of flow time after time. Gate valves work when you rotate them in a clockwise direction while closing your systems and vice versa when opening.
When in use, a gate valve moves up or down. The movement happens on its thread which moves the operator on its stem to close or open a system. And because of the valve’s up and down motion, you can use it to open various systems considering such valves work as multi-turn valves. And multi-turning means the valve can turn several times when opening and closing an application system; thereby, you can use it to open different application systems regardless of whether they close and open in clockwise or anticlockwise directions.
In addition, most gate valves prevent processing applications from experiencing the water hammer effects. The water hammer effect is when pipes and valves malfunction when the liquid pressure turns abruptly from an on position to an off position. And the water hammer effect phenomena can occur in a processing application that deals with liquid or even gases. Plus, when this phenomenon occurs, there is an abrupt surge of pressure that interferes with the flow of fluid and steam. And as a result, pipes and valves get destroyed depending on the severity of the pressure surge.
The Globe Control Valves
Globe valves are among the most popular control valves in the market today, and they differ from others by having sphere-shaped bodies. Also, the inside of a globe glove has baffles that separate it into two. And as the valve divides into two internal sections, it creates internal structures that allow the processing content to flow by following a path in a linear movement. In addition, unlike their counterparts, you will need globe valves when you have a processing application system that needs throttling.
Because of the throttling, you will be able to rotate the valve’s handwheels at the rate you want the processing commodity to flow. Or, the valves also allow you to adjust the desired levels of the processing commodity you want. Also, because of their linear motion, most glove valves will enable you to initiate the flow of the processing commodity, stop it and even regulate its flow instantly. This way, the valves also help you create an instant closure of a processing application that might be facing malfunctions immediately via a plug that contains a convex bottom and a flat surface that instantly lowers the flow of the processing content.
The Pinch Valves
Pinch valves are for shut-off and control purposes in most processing applications. These valves are also the best fit to control and regulate abrasive, corrosive, and granular media processing. They work by using pressurized air to open and close any processing application system. And more importantly, pinch valves don’t have restrictions in opening or closing, making them an excellent option for closing and opening a wide range of media passing through pipes and bores.
