P203 and P203H Commercial Industrial

The BelGAS P203 and P203H gas pressure reducing regulators come with an actual monitor regulator, acting independently of the primary regulator for commercial or industrial service applications.

BelGas Gas Pressure Reducing Regulators

When comparing to a standard two-regulator monitor setup, the BelGAS solution provides equal overpressure protection. If one regulator fails, the other will provide control and overpressure protection.

The BelGAS fast action reduces the risk of shock from sudden changes in downstream conditions and helps prevent safety equipment from causing unnecessary and expensive operation shutdowns.
