Different types of Pressure regulator


Before reading it understand what is pressure regulator?

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
