Types, Specs, and Selection Guide"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">Control valves control the flow of fluids and gas, in a pipeline. Control valves keep the flow steady and safe. They may turn a line to or off, regulate the rate or volume of the flow, keep a level of water constant or adjust the heat transfer to a room. The choice of a valve is not only associated with the diameter of the pipeline, but also the type of the valves, actuators, type of medium, connection type and installation location. Control valves are used in places from water storage tanks and heating systems to hydraulic machinery and food and medicine production. Each type is built for a job like controlling air, managing flow, regulating level or adjusting room temperature. Knowing the differences between these types along, with their sizes, materials and how they operate makes it easier to pick a valve that works with your system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a><\/a><strong>What Are Control Valves?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A control valve is a device to regulate the fluid or gas flow in a pipeline. Depending on the type, the valve may turn the flow on or off, the flow rate and volume, maintain the level of water or regulate the heat of the room.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a><\/a><strong>Main Types of Control Valves<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Air Control Valves<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">These&nbsp; <a href=\"https:\/\/www.ato.com\/air-control-valves\" target=\"_blank\" rel=\"noopener\"><strong>air control valves<\/strong><\/a> are operated by means of compressed air, enabling the opening and closing of the flow line. This 2-position, double-acting valve uses PTFE sealing and is available in 6 sizes from 1\/2&#8243; (DN15) to 2&#8243; (DN50). They are suitable for food, pharmaceutical, chemical, oil and gas, and water treatment applications and the 2&#8243; size is suitable for use with neutral liquids and gases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Hydraulic Flow Control Valves<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hydraulic Flow Control Valves with screw connection control the flow rate and pressure of the medium in a hydraulic circuit. They are simple in design, easy to adjust and come in sizes, like 1\/4&#8243; 3\/8&#8243; 1\/2&#8243; and 3\/4&#8243;. They are used in types of industrial equipment, construction tools and farming machines. They are also found in aerospace systems and car parts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Level Control Valves<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">These valves ensure a constant water level in the tank or reservoir independent of the inflow\/outflow of water.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Automatic water level valves (1\/2&#8243;, 3\/4&#8243;, 1&#8243;): stainless steel 304 body with screw connection; suitable for irrigation and water supply systems<\/li>\n\n\n\n<li>Float valves (DN50 to DN250) are engineered so that the float opens and shuts the valve automatically. The float valve does not require power. Float valves work well with non\u2011corrosive liquids up, to +80\u00b0C.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Radiator Thermostatic Valves<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Radiator Thermostatic Valves control the temperature in a room. Valves do this by regulating the flow of water into a radiator.They are mounted to the lower part of the radiator and are available in 15, 20 and 25 mm sizes in straight and corner versions, both manual or automatic. The 3-way manual version (3\/4&#8243; \/ 20 mm) is also available. They are used primarily in hot water heating and air conditioning systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a><\/a><strong>How Do Control Valves Work?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For each type of valve, the working principle is different:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Air control valves<\/strong> are designed with a two-position pneumatic actuator, and the compressed air moves the actuator diaphragm, hence opening or closing the valve.<\/li>\n\n\n\n<li><strong>Hydraulic flow control valves<\/strong> are a type of throttling valve with a narrow channel, and a screw connection. The valve adjusts the flow rate and pressure of the media in the pipeline. By turning the screw, it is possible to change the width of the channel and, thus, the flow rate. They are simple in design and are used in hydraulic systems.<\/li>\n\n\n\n<li><strong>Level control valves<\/strong> use a float that is opened or closed by the flowing water when the water level rises or falls.<\/li>\n\n\n\n<li><strong>Thermostatic radiator valves<\/strong> are attached to the radiator and, by adjusting the flow of hot water, regulate the temperature of the room.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">All types of control valves have their advantages and are suitable for different tasks. Here is a list of the common valves. Each valve includes a description, a working principle, for the valve and the fields where the valve is used.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a><\/a><strong>Key Specifications to Check Before Buying<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When selecting a control valve, for an application you must check a handful of important specifications. First of all, it is essential to determine which type of valve is required. According to the task, control valves can be used for different purposes: regulating the flow rate or volume of fluid, maintaining the level of water or regulating the temperature. Below are the basic specifications to examine when purchasing a valve.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Type and Function<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It is vital to determine what is the purpose of the valve. For example, an air control valve is used to turn a pipeline on or off by compressed air, a flow control valve is used to regulate the flow rate and volume of fluid, a level control valve maintains the level of water, and a thermostatic valve regulates the temperature.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Size and Connection<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The control valves are available in various sizes and screw connections, such as 1\/2\u201d (DN15) or 2\u201d (DN50). It is essential to make sure that the size of the valve corresponds to the size of the pipeline and the type of connection. The majority of the valves described above are provided with screw connections, meaning that there should be a matching screw connection in the pipeline.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Medium and Temperature<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It is also necessary to ensure that the valve is suitable for the fluid or gas that will flow through the pipeline, as well as the temperature of the medium. For example, control valves with a DN50DN250 range are suitable for use with clean water, and non-corrosive liquids in a moderate temperature range (up to +80C). A 2\u201d air control valve is suitable for use with neutral liquid and gaseous media. The application of a valve with an inappropriate medium can lead to the failure of the device.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Body and Sealing Materials<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The material of the valve body is also essential since the control valves are subjected to the pressure of the fluid or gas, and improper materials lead to leaking or malfunction. For example, automatic water level control valves are made of stainless steel 304 and air control valves are made of PTFE as a sealing material. The material can be found in the product description.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Actuation and Mode<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The mode of the valve can also be a critical factor in some applications. For example, air control valves are pneumatic and are double acting. Radiator thermostatic valves can be manual or automatic, while level control valves are self-acting (by float).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a><strong>Mounting and Installation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The last essential specification is the type of mounting. Some types of control valves are provided with mounting brackets, which can be narrow or wide, and some of them can also be mounted in different ways. For example, automatic water level control valves can be mounted in the top side or from the side. Radiator thermostatic valves can also be mounted in two different types.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"936\" height=\"770\" src=\"https:\/\/www.fontmirror.com\/en\/wp-content\/uploads\/2026\/10\/Sans-titre-19.png\" alt=\"\" class=\"wp-image-3949\" style=\"width:605px;height:auto\" srcset=\"https:\/\/www.fontmirror.com\/en\/wp-content\/uploads\/2026\/10\/Sans-titre-19.png 936w, https:\/\/www.fontmirror.com\/en\/wp-content\/uploads\/2026\/10\/Sans-titre-19-300x247.png 300w, https:\/\/www.fontmirror.com\/en\/wp-content\/uploads\/2026\/10\/Sans-titre-19-768x632.png 768w\" sizes=\"auto, (max-width: 936px) 100vw, 936px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><a><\/a><strong>How to Choose the Right Size?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The size of the valve is mostly determined by the pipeline. However, the valve size should also depend on the flow rate in the pipeline. The following steps should be taken to determine the size of the valve:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>First pipeline size must be determined. Then valve size must match pipeline size and connection type as 1\/2 inch (DN15) or 2 inch (DN50).<\/li>\n\n\n\n<li>The next task type must be identified. For example control valves may need to turn the pipeline on or off, reduce or regulate flow rate keep water level control temperature.<\/li>\n\n\n\n<li>After that, it is necessary to determine what medium will flow through the pipeline. For example, valves with a DN50DN250 range are suitable for use with clean water, and non-corrosive liquids in a moderate temperature range (up to +80C).<\/li>\n\n\n\n<li>Finally, a few recommended applications should also be considered. The control Valves can be used for devices (hydraulic flow control valves) for farms that use level control valves and for the food and medicine industry that uses air control valves. Valves are fit many needs.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Comparing the control valves based on their specifications helps in selecting the valves that fit the exact needs. It&#8217;s important to keep in mind that picking a valve that&#8217;s too small can hurt performance. On the other hand , choosing a valve that is too big can cost more than needed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a><\/a><strong>How Control Valves Impact Our Daily Lives and Technological Advancements<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Even if most people never actually see a control valve these devices work hard every day behind the scenes. They help keep things running smoothly in different systems. You might not notice them. They are always there doing their job.Here are some examples:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>At home:<\/strong> A water level control valve in the storage tank ensures that the water supply is available whenever needed. Thermostatic radiator valves are used in a hot water heating system to provide a comfortable temperature in each room of the house.<\/li>\n\n\n\n<li><strong>On the farm:<\/strong> Automatic water level control valves can help to control the flow of water in agricultural irrigation systems. Hydraulic flow control valves can also be used in agricultural machinery.<\/li>\n\n\n\n<li><strong>In food and medicine:<\/strong> Air control valves are used to open and close pipelines in the production of a variety of goods, from food and beverages to medicines.
