There are numerous types of pressure regulators, but they primarily fall into two categories reducing regulators and back-pressure regulators. Reducing regulators are most commonly used in systems where a known high pressure needs to be lowered for safe distribution, such as in heating systems or gas delivery networks. On the other hand, back-pressure regulators maintain a specific upstream pressure by allowing excess fluid or gas to escape when necessary. This type is often employed in processes like wastewater treatment or chemical manufacturing to ensure that systems operate within safe and optimal conditions.
