They can automatically do the job and eliminate the need for you to constantly keep an eye on the system. You can choose the correct control valve for the specific desired pressure. It\u2019s interesting to know that Control Valves are also known as the final control element in automatic control terminology which is due to the process control valves operating within their system.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_pressure_control_valve\"><\/span>What is a pressure control valve?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The valve basically controls the fluid flow. Control valves operate by varying the size of the flow passage. Control valves can directly control the flow rate and the quantities like temperature, pressure, and liquid level. Pressure control valve is responsible for keeping the system pressures in the right range toward the desired limit. They can help maintain the set pressure safely in the system they are operating in. You can find them in almost all hydraulic systems these days.<\/p>\n<p>Pressure control valves have different types such as unloading, relief, sequence, reducing, and counterbalance. In order to achieve the required pressure control with the help of these pressure control valves, a restriction is needed. And almost all of these types are usually closed valves and only the reducing type is usually open.<\/p>\n<p><img decoding=\"async\" class=\"size-full wp-image-811 aligncenter\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Control-Valves-1.jpg\" alt=\"Control Valves - Linquip\" width=\"400\" height=\"514\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Control-Valves-1.jpg 400w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Control-Valves-1-233x300.jpg 233w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Control-Valves-1-327x420.jpg 327w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><em><strong>Read More on Linquip<\/strong><\/em><\/p>\n<ul>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"What is Actuator Valve\" href=\"https:\/\/www.linquip.com\/industrial-directories\/836\/actuator\" target=\"_blank\" rel=\"noopener\" data-schema-attribute=\"\">What is Actuator Valve<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"What is Air release valve\" href=\"https:\/\/www.linquip.com\/industrial-directories\/992\/air-release-valve\" target=\"_blank\" rel=\"noopener\" data-schema-attribute=\"\">What is Air release valve<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"What is Angle Valve\" href=\"https:\/\/www.linquip.com\/industrial-directories\/340\/angle-valve\" target=\"_blank\" rel=\"noopener\" data-schema-attribute=\"\">What is Angle Valve<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"What is Ball Valve\" href=\"https:\/\/www.linquip.com\/industrial-directories\/341\/ball-valve\" target=\"_blank\" rel=\"noopener\" data-schema-attribute=\"\">What is Ball Valve<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"What is Bleeder Valve\" href=\"https:\/\/www.linquip.com\/industrial-directories\/997\/bleeder-valve\" target=\"_blank\" rel=\"noopener\" data-schema-attribute=\"\">What is Bleeder Valve<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><a title=\"Working Principle of Control Valve\" href=\"https:\/\/www.linquip.com\/blog\/working-principle-of-control-valve\/\" target=\"_blank\" rel=\"noopener\"><strong><span style=\"font-size: 10pt;\">Working Principle of Control Valve<\/span><\/strong><\/a><\/span><\/li>\n<li><span style=\"text-decoration: underline;\"><strong><span style=\"font-size: 10pt;\"><a title=\"Top Control Valve Suppliers in the USA\" href=\"https:\/\/www.linquip.com\/blog\/top-control-valve-suppliers-in-the-usa\/\" target=\"_blank\" rel=\"noopener\">Top Control Valve Suppliers in the USA<\/a><\/span><\/strong><\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Control_Valves_Principles_of_Operation\"><\/span>Control Valves Principles of Operation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Now let\u2019s dig deeper into how control valves operate and what to expect when working with one.<\/p>\n<p>Control valves try to keep the variables of a flowing fluid, like chemical compounds, steam, gas, and water close to the desired set point by manipulating the flowing fluid. The control signal here which could be either electronic or pneumatic, manipulates the CV and changes its location, resulting in the accurate control of the flowing fluid and reaching the profitable production requirements. It also helps saving money by reducing unnecessary costs.<\/p>\n<p>Hydraulic, electrical, or pneumatic actuators are responsible for opening or closing automatic control valves and the valve positioners with the help of a modulating valve that can adjust the desired degree of opening of the valve. These modulating valves can be set to different positions from fully open to fully closed based on the desired outcome.<\/p>\n<p>The only thing required for air-actuated valves (pneumatics control valve) is a compressed air supply, making it the most commonly used type due to its simplicity, whereas other valves such as electrically operated valves need additional switchgear and cabling. Hydraulically-actuated valves also need a high-pressure supply as well as return lines for the hydraulic fluid.<\/p>\n<p>Air-actuated (pneumatic) control signals are normally operating on a pressure range of 3-15psi (0.2 \u2013 1.0 bar). For industry, an electrical signal of 4-20mA, as well as 0-10V for HVAC system, is required.<\/p>\n<p>State-of-the-art electrical control these days uses smart communication signal for 4 to 20mA control current. It can signal back the health of the valve and verify its position to the controller.<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.linquip.com\/industrial-directories\/998\/mixing-valve\/for-sale\/?utm_source=blog&amp;utm_medium=content&amp;utm_campaign=CRO&amp;utm_term=control_valves&amp;utm_content=for_sale\" target=\"_blank\" rel=\"noopener\"><span style=\"text-decoration: underline;\"><strong>See All Mixing Valve for Sale<\/strong> <\/span><\/a><\/p>\n<p><img decoding=\"async\" class=\"size-full wp-image-812 aligncenter\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Electric-Actuator.jpg\" alt=\"Control Valves - Linquip\" width=\"700\" height=\"466\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Electric-Actuator.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Electric-Actuator-300x200.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Electric-Actuator-696x463.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/06\/Electric-Actuator-631x420.jpg 631w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p><em><strong>Read More on Linquip<\/strong><\/em><\/p>\n<ul>\n<li><span style=\"text-decoration: underline;

We\u2019ll briefly cover the most popular ones.<\/p>\n<p>How CVs are classified is according to different features such as pressure drop profile, movement profile of the controlling element, actuating medium and functionality.<\/p>\n<p>When classifying control valves based on the pressure drop profile, there would be two common types including High-Recovery valve and Low-Recovery valve. Butterfly Valve, Plug Valve, Gate Valve, and Ball Valve are all considered as high-recovery valve type. Low-Recovery valve type includes Angle Valve and Globe Valve.<\/p>\n<p>Control valves categorization based on functionality includes: Check Valve (e.g.: Turbine bypass valve), Shut-off and On-Off Valve (e.g.: Gate Valve, Pinch Valve), and Spring-Loaded Safety Valve.<\/p>\n<p>When choosing control valves based on the movement profile of the controlling element, you have two options: Sliding Stem, and Rotary Valve. These two popular control valve types are separated based on their movement. In the Sliding stem, the valve moves in a straight-line motion, whereas in the Rotary Valve, the valve disc has a rotary motion. Examples on the first one is: Globe Valve, Wedge type gate valve, Angle Valve, etc. and examples of the Rotary valve includes: Ball Valve, and the Butterfly Valve.<\/p>\n<p>Last but not least is separating control valves based on the actuating medium. This feature includes different types such as Manual Valve, Pneumatic Valve, and Hydraulic Valve.<\/p>\n<p><em><strong>Read More on Linquip<\/strong><\/em><\/p>\n<ul>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"Industrial Valves A Comprehensive Review on Parts, Types and its Usability\" href=\"https:\/\/www.linquip.com\/blog\/industrial-valves\/\" target=\"_blank\" rel=\"noopener\">Industrial Valves A Comprehensive Review on Parts, Types and its Usability<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"Control valve positioner: an easy-to-understand guide to know them better\" href=\"https:\/\/www.linquip.com\/blog\/control-valve-positioner\/\" target=\"_blank\" rel=\"noopener\">Control valve positioner: an easy-to-understand guide to know them better<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a href=\"https:\/\/www.linquip.com\/blog\/flow-control-valve-types-and-functions\/\" target=\"_blank\" rel=\"noopener noreferrer\">Flow control valve types and functions<\/a>\u00a0<\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"Control Valve Types 101: Different classifications, advantage, and disadvantages\" href=\"https:\/\/www.linquip.com\/blog\/control-valve-types\/\" target=\"_blank\" rel=\"noopener\">Control Valve Types 101: Different classifications, advantage, and disadvantages<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"Control Valve Parts: The Go-To Guide for beginners and experts\" href=\"https:\/\/www.linquip.com\/blog\/control-valve-parts\/\" target=\"_blank\" rel=\"noopener\">Control Valve Parts: The Go-To Guide for beginners and experts<\/a><\/strong><\/span><\/li>\n<li><span style=\"text-decoration: underline; font-size: 10pt;\"><strong><a title=\"Facts About The Flow Control Valve Function\" href=\"https:\/\/www.linquip.com\/blog\/facts-about-the-flow-control-valve-function\/\" target=\"_blank\" rel=\"noopener\">Facts About The Flow Control Valve Function<\/a><\/strong><\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Advantages_of_using_Control_Valves\"><\/span>Advantages of using Control Valves<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>High performance as well as easy maintenance are only a few of the great features a high-quality control valve has to offer.
