To achieve this, it is clear that you need a controller, such as a Programmable Logic Controller (PLC). <\/p>\n<p>Some sensors and transmitters also need to send data to the PLC or DCS. Finally, you need a device (often called the &#8220;final control element&#8221;) to execute the commands from the PLC. <\/p>\n<p>Actuators include pumps, heaters, control valves, and similar devices. <\/p>\n<p>Typically, these control valves are not used in fully open or fully closed positions. Proportional control valves with specially designed throttling plates are used to restrict flow or regulate flow rate. This allows you to, for example, control the heating time of a furnace, the filling rate of a tank, or reduce the pressure in a line.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"wd-negative-gap elementor-section elementor-top-section elementor-element elementor-element-b1d58d8 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"b1d58d8\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-83a26db\" data-id=\"83a26db\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-83efed5 elementor-widget elementor-widget-image\" data-id=\"83efed5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"768\" height=\"445\" src=\"https:\/\/unox.com.tr\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/01\/kontrol-vanasi-nedir-768x445.jpg\" class=\"attachment-medium_large size-medium_large wp-image-58775\" alt=\"\" srcset=\"\" data-srcset=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/01\/kontrol-vanasi-nedir-768x445.jpg 768w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/01\/kontrol-vanasi-nedir-150x87.jpg 150w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/01\/kontrol-vanasi-nedir-600x348.jpg 600w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/01\/kontrol-vanasi-nedir-300x174.jpg 300w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/01\/kontrol-vanasi-nedir-1024x594.jpg 1024w, https:\/\/unox.com.tr\/wp-content\/uploads\/2024\/01\/kontrol-vanasi-nedir.jpg 1250w\" sizes=\"(max-width: 768px) 100vw, 768px\" title=\"\">\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"wd-negative-gap elementor-section elementor-top-section elementor-element elementor-element-2422665 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"2422665\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-a5c98fd\" data-id=\"a5c98fd\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-1cd96ec elementor-widget elementor-widget-wd_text_block\" data-id=\"1cd96ec\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"wd_text_block.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"wd-text-block reset-last-child text-left\">\n\t\t\t\n\t\t\t<h2><span class=\"ez-toc-section\" id=\"Control_Valve_Components\"><\/span><strong>Control Valve Components<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Body: The part through which the fluid passes and comes into contact is called the body.<\/p>\n<p>Actuator: The actuator can be electric or pneumatic and allows the valve to open and close using auxiliary power.<\/p>\n<p>Trim elemanlar: Sit, klepe ve klepe mili olarak adland\u0131rl\u0131r bu k\u0131s\u0131mlar paslanmaz malzemeden olu\u015fup ak\u0131\u015fganlar temas eden k\u0131s\u0131mlard\u0131r ve farkl\u0131 uygulamalarda farkl\u0131 malzeme \u00e7e\u015fitleri kullan\u0131labilir.<\/p>\n<p>Positioner: Typically used to send commands to a pneumatic actuator, positioners come in types such as with or without feedback, self-calibrating, or HART protocol compatible.
