Valve Torque Calculator
Calculates the precise gland bolt torque needed for packing valves to meet modern fugitive emissions standards. It helps balance low leakage with acceptable stem friction, ensuring compliance with EPA Method 21 for up to 5 years.
- Calculates gland bolt torque
- Supports Chesterton style 1622 and 1724E packing
- Input stuffing box and stud dimensions
- Accounts for lubricant used
- Supports Inch and Metric units
- Ensures leak levels below 100ppm

Modern fugitive emissions standards require a different approach to sealing valves with packed stuffing boxes. Even more than before the balance between leakage and stem friction becomes more important. For this reason it is crucial to tighten packing with a calculated force that keeps the balance between low emission levels and acceptable stem friction. This tool calculates the gland bolt torque for valves that are packed with Chesterton style 1622 Low Emission Packing or Chesterton style 1724E Low Emission Sealing Sets. It requires the entry of the stuffing box inner and outer diameter, the stud diameter and number of studs and the entry of the lubricant used when tightening the valve. The tool works both in Inch and Metric units. The generated torque is the torque that should be applied to the gland nuts. The installation instructions of the packing used should always be followed in detail. When using the torque in this tool and following the installation instructions of the packing, the leak level of the packing is guaranteed to stay below 100ppm, as measured following EPA Method 21, for duration of 5 years*. *see the Chesterton Valve Emissions Warranty for conditions that apply

Verdict
The clearest difference is update cadence: Valve Torque Calculator at every 12 months against Torque Unit Calculator's every 30 months. Valve Torque Calculator also leads on device support (3 vs 1) and iOS requirement (8.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
