Which tool should I use?

  • Use the General Sizing Tool if you know your pressures and load but don't yet know which regulator model you need.
  • Use an individual model tool if you already know the model and want to size that specific regulator.

Preliminary selection only. These tools provide a starting point based on the values entered and do not account for every variable in a field installation — including inlet pressure variation, ambient temperature, elevation, piping losses, venting requirements, over-pressure protection strategy, and applicable codes. Final regulator selection, installation and setting must be performed by qualified personnel in accordance with the product installation and maintenance manual and all applicable federal, state and local codes. Improper regulator selection or installation can result in over-pressurization, property damage, serious injury or death. Contact Holland Supply Company to review any selection before ordering.
