Sanitary control valves are made with materials approved for use in food or pharma industries; are polished to a specified roughness (Ra) finish; and are designed for easy cleanability to prevent contamination. Sanitary valves must meet rigorous standards for hygiene and cleanliness. In addition to biopharmaceutical and food &amp; beverage applications, sanitary valves are used in health &amp; beauty and confectionery industries.<\/p> <p><a id=\"button-counter-1\" class=\"button medium type-simple\" href=\"\/contact\/\" >Contact Us to Learn More<\/a> <a id=\"button-counter-2\" class=\"button medium type-simple\" href=\"\/PDF\/Equilibar-Sanitary_FD_Series-Back_Pressure_Regulators.pdf\" >Download FD Brochure<\/a><\/p> <h3>Equilibar Sanitary Flow Control Benefits<\/h3> <ul> <li>Wide operating range with a turn down ratio of 200:1 (wider range than traditional valves)<\/li> <li>Sizes for low flow control down to Cv of 1E-6 and high flow control up to Cv of 36<\/li> <li>Controls flow in applications with low DP or with extremely high DP<\/li> <li>Compact size for easier integration<\/li> <li>Easy and inexpensive to maintain in the field<\/li> <\/ul> <h3>What is a flow control valve?<\/h3> <p>A \u201ccontrol valve\u201d is a general term for any valve that controls the size of the fluid passageway as a means of controlling flow, pressure, or other process parameters related to flow. By adjusting a positioner or knob, the cross-sectional area of the fluid pathway can be changed to modulate the flow through the valve. As the positioner moves, it changes the \u201c% open\u201d of a valve which changes the flow rate through the valve. Different valve designs have different flow curves for \u201c% open\u201d versus \u201cflow rate.\u201d Flow control valves (FCVs) are used when flow rate is an important process parameter in product outcomes.<\/p> <p>Flow control valves are commonly used in closed loop control with a flow meter. The flow meter sends flow rate to a controller, which then sends a command signal to an actuator or positioner to set a specific \u201c% open\u201d of the control valve to keep the flow rate on target. Flow control valves come in many different forms, including globe, butterfly, ball, pinch and diaphragm valves.<\/p> <a id=\"button-counter-3\" class=\"button medium type-simple\" href=\"\/PDF\/Equilibar-Sanitary_FD_Series-Back_Pressure_Regulators.pdf\" >Download FD Brochure<\/a> <h3>How Equilibar Sanitary Flow Control Valves Work<\/h3> <p>Equilibar sanitary flow control valves are dome-loaded valves with a supple diaphragm that modulates up and down to adjust flow rate. Because they are dome-loaded, a pressurized pilot gas (usually air) is applied to the top of the diaphragm to maintain the setpoint of the process. The Equilibar sanitary FCV works in a control loop with an electronic pressure controller and a flow meter. The novel design allows for an extremely wide operating range and fast response to maintain accurate flow setpoints for critical sanitary applications.<\/p> <p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-43857\" src=\"\/wp-content\/uploads\/2025\/06\/Sanitary-flow-control-how-it-works-schematic.gif\" alt=\"schematic of how it works for sanitary flow control\" width=\"832\" height=\"333\" \/><\/p> <p>A proportional-integral-derivative (PID) controller monitors input from a flow transmitter (FT) and adjusts the pilot pressure to bring flow under control. An electro-pneumatic (E\/P) pressure controller translates the electronic signal from the PID into a pressure signal for the pilot pressure setpoint. Flow is decreased by raising the pilot pressure and increased by lowering the pilot pressure.<\/p> <a id=\"button-counter-4\" class=\"button medium type-simple\" href=\"\/contact\/\" >Contact Us to Learn More<\/a> <h3>Equilibar FDO Sanitary Valves Specifications<\/h3> <p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-43866\" src=\"\/wp-content\/uploads\/2025\/06\/FDO-specification-table-.gif\" alt=\"specification table data for FDO\" width=\"686\" height=\"411\" \/><\/p> <a id=\"button-counter-5\" class=\"button medium type-simple\" href=\"\/PDF\/Equilibar-Sanitary_FD_Series-Back_Pressure_Regulators.pdf\" >Download FD Brochure<\/a> <\/div><div class=\"c-one-third \"> <div id=\"attachment_30870\" style=\"width: 410px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-30870\" class=\"wp-image-30870 size-full\" src=\"https:\/\/www.equilibar.com\/wp-content\/uploads\/2021\/12\/flow-control-setup-image-web.jpg\" alt=\"advanced flow control using equilibar valves\" width=\"400\" height=\"307\" srcset=\"https:\/\/www.equilibar.com\/wp-content\/uploads\/2021\/12\/flow-control-setup-image-web.jpg 400w, https:\/\/www.equilibar.com\/wp-content\/uploads\/2021\/12\/flow-control-setup-image-web-300x230.jpg 300w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-30870\" class=\"wp-caption-text\">Equilibar FDO4 valve in a flow control loop with an Equilibar EPR-150 electronic pilot regulator and a high resolution flow meter.
