Single-stage regulators shall have a maximum outlet pressure setting of _______.

Single-stage regulators are designed to provide a specific function in propane systems, typically used in applications where the pressure requirements are not excessively high. The maximum outlet pressure setting of 1.0 psig for single-stage regulators is established to ensure safety and proper functioning.

This pressure range allows the regulator to efficiently manage the flow and pressure of propane while minimizing the risk of over-pressurization, which could lead to potential hazards. Using a regulator set at 1.0 psig is also a standard in many applications, particularly in residential heating, where the pressure requirements are well within this limit.

The correct outlet pressure setting aligns with both manufacturer specifications and industry safety standards, ensuring reliable operation in various systems without risking equipment damage or safety hazards.
