BACK TO GLOSSARY

An air-loaded valve or regulator is operated by a static air signal applied to the top of a diaphragm or piston to determine the set point. It requires no control spring or pilot. 

Equilibar designs and manufactures dome-loaded back pressure regulators, which is similar to air-loaded but uses a continuous air signal to the top of a diaphragm to determine the pressure set point. It also requires no control spring. Because the air signal is continuous, it automatically adjusts for process changes upstream and downstream.
