Glossary of Terms
Sensing Element
One of three basic elements of a pressure Regulator. Senses the
changes in the control pressure (or process line) which allows
the regulator to react and attempt to return to the original set
pressure. Diaphragm and Piston are the two most commonly used
sensing elements.
Set Pressure
The desired operational control pressure for a Regulator, normally
stated at FIRST FLOW conditions.
Venting Regulator
A pressure reducing Regulator that can vent the Outlet Pressure
(downstream pressure) when the loading/actuation force is
decreased. A decrease in Pilot Pressure causes the regulator to vent.
