What Makes a Regulator?

Gas Pilot Operated Regulators

Three Basic Types of Regulation Back Pressure Pressure Reducing Pressure Differential

Back Pressure Regulator Maintains Constant Upstream Pressure FLOW

Back Pressure Regulator Maintains Constant Lower Downstream Pressure FLOW

Back Pressure Regulator Maintains Constant Differential Pressure FLOW

Back Pressure Regulator

Operation – Back Pressure Regulator Spring Opposes Upstream Pressure Pilot Supplies Pressure To Main Diaphragm Pilot Diaphragm Senses Upstream Pressure Seat Releases Right Amount of Gas To Control Upstream Pressure Upstream Pressure
