Regulator Sizing Tools / Model 243
Large-capacity regulator for commercial, industrial and gas distribution service, with interchangeable bodies and diaphragm cases. Available with an internal relief valve, a low-pressure cut-off, or in a high-pressure configuration.
Note: The tool cannot size an internal relief valve above 2 psi set point. If an internal relief valve cannot be sized, then the program will attempt to size a monitor regulator for overpressure protection.

Preliminary selection only. This tool provides a starting point based on the values entered and does 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.
