  1. DOE FOR THE CUSTOMER Chris Vandegrift V.P. of Engineering Selas Heat Technology

  2. 4BZR Regulator Objective: • Launch the 4BZR – ½” regulator • Conduct performance tests with various conditions: flow rate, pressure variation, washer weights, spring properties and diaphragms. • Meet or exceed the current standard for constant pressure output from the regulator

  3. 4BZR Before Summer 2013 ½” Balanced Zero Regulator Erratic performance on shut-off

  4. “On-Target with minimum variance.”“Operating with minimum variance is achieved only when a process displays a reasonable degree of statistical control.”-Walter A. Shewhart Variation

  5. Virtual Fishbone

  6. Design of Experiments (DOE) • Design of experiments is a branch of applied statistics that deals with… • Planning • Conducting • Analyzing • Interpreting …controlled tests to evaluate the factors that impact the output of the regulator.

  7. 4BZR DOE – Main Effects Main Nut Setting Seal Nut Setting Seal Washer Diameter

  8. 4BZR After DOE

  9. 4BZR Response Optimizer Optimal Settings

  10. 4BZR Test Rig Objective: To test Balanced Zero Regulators performance against quality standards. The ability to digitally record and display test data.
