Abstract: The definition of a large capacity regulator is often difficult to formalize. There are many types of regulators which could be classified as large capacity. This discussion will be concerned with the conventional double ported regulator. The double ported balanced valve regulator is probably the most commonly used style of regulator labeled as large capacity. The large capacity is also often classified as high pressure due to the function of the restriction. The restricting element Is positioned by an operator to permit equal flow into and out of the downstream system. The capacity of a restrictor is a function of the pressure differential across that restriction, therefore, the higher the pressure differential across the restrictor the greater the capacity for a given size restriction. The capacity will increase until sonic flow occurs. Sonic flow is the point at which the gas velocity reaches the speed of sound, and occurs when the outlet pressure absolute Is approximately half the inlet pressure absolute.
