Industrial Valves, Actuators & Flow Control calculator
Actuator Sizing Workload Calculator
Use this calculator to estimate the total engineering hours required to size actuators for a valve automation project. Actuator sizing involves matching actuator output torque or thrust to valve operating torque across the full stroke, confirming safety factors, and selecting the correct actuator model. Enter the number of valve-actuator pairs to size, the average engineering time per sizing (data gathering, calculation, selection), and an overhead allowance for reviews, revisions, and vendor coordination.
What this calculator does
- Estimate total engineering hours needed to complete actuator sizing calculations for a project, based on valve count, average sizing time per valve-actuator pair, and review and revision overhead.
- Use this when scoping engineering hours for an automation project that requires sizing pneumatic, electric, or hydraulic actuators to match valve torque or thrust requirements.
- Turns valve-actuator pairs to size, average engineering hours per sizing, review, revision, and coordination overhead into a adjusted run time for actuator sizing workload in industrial valves, actuators and flow control.
Formula used
- Base sizing hours = valve-actuator pairs x hours per sizing
- Total actuator sizing workload = base hours x (1 + overhead / 100)
Inputs explained
- Valve-actuator pairs to size: Count each unique valve and actuator combination requiring a sizing calculation. Include spares or alternates if they need separate sizing sheets.
- Average engineering hours per sizing: Include time for valve datasheet review, torque or thrust calculation, safety factor verification, actuator model selection, and documentation. Typical range: 1 to 4 hours per pair.
- Review, revision, and coordination overhead: Add time for peer review, customer or consultant comment resolution, vendor technical queries, and document revision cycles. Typical range: 15% to 40%.
How to use the result
- Reach for it when a customer asks for a lead time and you need a number you can defend in 30 seconds.
- Setup, changeover, and major stoppages are not in the formula. Add them on top for industrial valves, actuators and flow control jobs that include them.
Common questions
- What does the actuator sizing workload calculator give me? Estimate total engineering hours needed to complete actuator sizing calculations for a project, based on valve count, average sizing time per valve-actuator pair, and review and revision overhead. You get a adjusted run time you can defend before quoting, scheduling, or sign-off.
- What numbers should I focus on first? valve-actuator pairs to size, average engineering hours per sizing, review, revision, and coordination overhead usually move the adjusted run time most. Pull from measured industrial valves, actuators and flow control runs, supplier data, and recent quotes rather than memory.
- How should I act on the output? Run a fast what-if before you change rate, allowance, or crew size on the next industrial valves, actuators and flow control job.
- What should I double-check before acting? Confirm the rate against a recent shift report, not the spec sheet, and account for changeover and setup that the calculator does not.
