Before reading it understand **[what is pressure regulator?](http://instrumentpedia.blogspot.com/2015/06/basics-of-pressure-regulator-pressure.html)**

**Back pressure regulator**

Designed to modulate to hold a specific back pressure Monitors and regulate upstream pressure Aka reverse acting regulators Droop = Build up

**Dome Loaded PRV** Eliminating spring - Extremely accurate Air signal across top of diaphragm Needs an air regulator or I/P faster than a control loop Increased rangeability Low minimum delta P requirement Good for frequently changing setpoint or remote installations

**Tank Blanketing Regulator** Gas blanketing or other low pressure air / gas applications Extremely large elastomer diaphragms for increased sensitivity Very light springs
