4BZR Regulator Performance Optimization for Constant Pressure Output

In this project led by Chris Vandegrift, V.P. of Engineering at Selas Heat Technology, the objective is to launch the ½” 4BZR regulator. Various tests are conducted to ensure it meets or exceeds current standards for constant pressure output. Walter A. Shewhart's concept of minimum variance in operational performance is a guiding principle. Utilizing Design of Experiments (DOE), factors such as main nut setting, seal washer diameter, and more are evaluated for optimal regulator performance. The 4BZR test rig is utilized to assess the regulator's performance against quality standards and to conduct marketing claim tests. For any queries, feel free to reach out.

  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
