Webinar Recap: Back Pressure Regulators 101
Posted by danstips in Jordan Valve, Process Valving, Regulators, Webinar on February 18, 2016
In case you missed last month’s webinar with Jordan Valve on back pressure regulators, we’ve put together some of the key points.
The Control Loop: 
Sensing element: measures the process variable being controlled, and send an output to the controlling instrument
Controlling instrument: calculates the error (difference in signal from sensing element and the desired setpoint) and sends corrective signal to final control element
Final control element: varies the flow to change the controlled variable to the required setpoint
Regulators 101: Pressure vs. Back Pressure

Let’s start with the basics.
What is a pressure regulator?
A pressure regulator is a normally-open valve used to regulate or reduce undesirable, high upstream pressure. The pressure regulator must be installed at the START of a system, before any pressure-sensitive equipment.
The valve is held open by springs, and a screw that sets spring force. When outlet pressure exceeds the setpoint, the valve will close. When the valve closes, pressure is reduced downstream.
