What is the maximum allowed regulator lockup pressure?

The maximum allowed regulator lockup pressure is 14 inches of water column (WC). This value is very important because it indicates the pressure at which the regulator will stop allowing gas to flow when the downstream pressure reaches this threshold, ensuring that the system operates safely and efficiently. Maintaining the lockup pressure within prescribed limits helps to prevent over-pressurizing downstream equipment, which could lead to system failures or safety hazards.

Regulators are designed with specific lockup pressure settings to accommodate various applications and ensure a proper balance between gas supply and demand. Exceeding the recommended lockup pressure could harm both the equipment and the integrity of the entire propane system. Hence, 14 inches WC is the maximum accepted standard in many gas codes and regulations, making it essential knowledge for technicians in the field.
