Our AV assemblies with 3R actuators are sized with these torques. Torque tables are provided for different actuator models showing rated Apr 1, 2008 · I am trying to determine the actuator torque required for my metal seated, eccentric (meaning offset) butterfly damper. *Calculation Standard : p : 500mmAq / One Wing Note: When the pressure and q'ty of Wings ared changed, Torque will be too different. If no additional information is available, use the following rule of thumb: 6 in-lb/ft2. Safety shall be added Dec 21, 2009 · How can I calculate the maximum torque required for a damper actuator? Or to put it another way, how do I calculate expected torque for my airflow in a circular duct? Jul 14, 2022 · How Do I Calculate Valve Actuator Torque? When specifying rotational valve actuators, it’s crucial to calculate your application’s torque settings correctly using accurate guide values. The document provides information about a pneumatic damper actuator manufactured by DAEJU CONTROL CO. damper control alone is itself not responsible for the indoor air quality and climate, but it has a very central role. 25 to the actual torque to ensure Jan 11, 2018 · Required actuator torque After obtaining the damper torque rating [Nm/m2] from the manufacturer and determining the damper area, calculate the total torque required to move the damper as follows: Total torque [Nm] = Torque rating [Nm/m2] × damper area [m2]. Retrofit and Replacement How to Select an Actuator for Damper Retrofit ® The “10 questions” method for sizing and selection shown below is recommended as the best method for your actuation requirements. I am using formulae from Appendix A of AWWA C504-87, titled "Suggested Method for Calculating Torques Required to Operate Rubber-Seated Butterfly Valves". Example: At 5" w. , LTD. , a parallel blade CD36 with seals would require 14 in. Multiply the duct area by this holding torque to determine the actual torque required to operate the damper. Learn about torque requirements for dampers to ensure proper actuator sizing and efficient system operation. Oct 22, 2025 · To size a damper actuator, first measure the duct's width and height to calculate its area. 039 to convert it into inches. The damper will be made in-house so there are no manufacturer damper torque ratings. Then, apply a safety factor of 1. Caution: To ensure proper actuator sizing use the manufacturer's recommendation for torque requirements. If so, multiply the millimeters by 0. . The customer may provide this in millimetres (mm). TYPICAL DAMPER REQUIREMENTS AND This sizing method results in oversized actuators which add unnecessary cost to the damper. Torque calculations can be broken into two categories — static torque and dynamic torque. To avoid this, it is recommended to calculate torque requirements based on actual operating conditions as described below. default to use the largest torque actuator possible Stroking the valve frequently, maintain the seats cleaner and the thrust and torque lower. Once in Inches, multiply the height and width and divide by 144 to get the area in Even if you are in design phase or consider to mount rotary dampers on your application, you can calculate required torque with just entering the number. Nov 22, 2023 · Learn the key role of torque in valve operations and how to estimate it for effective actuator sizing in quarter turn valves. of torque per square foot. Use the “Application Data” column in this chart as a worksheet to help in the selection process. Damper Actuator Torque Calculation Xls. The “10 questions” method for sizing and selection shown below is. One side calculates torque value and the other selects an appropriate actuator by control signal. The easy-to-use to use tool takes three steps and less than 30 sec. Energy-efficient, robust, flexible and reliable – save time and costs with OpenAir. damper standard torque calculation. 25 and insure that thrust estimate is a minimum of three times the weight of the gate. Based on the type of damper—either parallel blade or opposed blade—use the corresponding holding torque per unit area. Honeywell, Inc. It includes specifications for the actuator such as input signals, operating degree, air consumption, and temperature operating range. It will be calculated with horizontal position because it will be calculated required maximum torque to rotary dampers. 5 for exposed sluice gates (penstocks) multiply factors by 1. Is there a method to calculating the maximum torque of the damper in operation without using a damper torque rating? Also this is The right damper actuator for any HVAC application Our OpenAirTM series provides more torque sizes to meet all of your needs. The formula for Mar 1, 1998 · Damper Torque Calculator/ Direct Coupled Damper Actuator Selector looks and works like a slide rule. g. For inside screw threads multiply factors by 1. Instead of the torque rating, the total torque can also be det Mar 25, 2024 · Sizing/Selecting A Damper ActuatorThe Belimo 10 Step process for sizing and selecting a damper actuator: 1)What is the Area of the damper? We need to find the height and width of the damper. The updated catalog torques reflect calculations and sample selection from Recommended Practice S 2812-X-19 and represent the maximum torque value with three standard deviations. lbs. It also includes diagrams of the actuator components and installation examples. Manufacturer's torque requirements very greatly depending on seals, static pressure, velocity and damper design. With over 40 years of innovating control actuators, Siemens is a recognized global leader in HVAC damper actuators. DEI Operational Torque for Control Dampers: May 12, 2015 · I'm trying to calculate the maximum torque on a damper to select an actuator. Underpowering or overpowering a simple clockwise-counter-clockwise movement risks damaging or stalling the valve.
