What pressure should overpressure protection devices limit the gas pressure to each connected appliance?

Overpressure protection devices are designed to safeguard appliances from excessive gas pressure that could lead to malfunction, damage, or even safety hazards. In this context, limiting the gas pressure to 2 PSI for each connected appliance is aligned with industry standards and safety regulations. Maintaining this pressure helps ensure that the appliances function as intended while also reducing the risk of leaks or failures that might occur at higher pressures.

Setting the pressure limit to 2 PSI balances performance and safety, allowing the appliances to operate efficiently without compromising their integrity. Higher pressure settings, such as 5 PSI or 10 PSI, could potentially expose appliances to conditions beyond their operating tolerances, leading to increased wear and tear, and a higher likelihood of safety issues. As such, 2 PSI represents a prudent and accepted standard for overpressure protection in this scenario.
