Jordan Valves is promoting remotely set Pressure Reducing Valves (PRVs). These valves are equipped with dome-loaded regulators, which provide a closer degree of control than self-operated or pilot-operated valves, while providing greater flexibility. These regulators are an excellent choice where great accuracy is required (minimize droop), remote control is needed, or where the set point changes frequently.
Typical problems associated with controlling steam flows have generated many theories on how to improve the control loop; many of which are sophisticated and expensive.
A simpler approach might yield greater results in both temperature control and cost efficiency. Remotely set dome-loaded PRVs enable the steam equipment to operate and respond more quickly to varying conditions. The regulator allows more flow to pass more quickly upon sensing a loss of pressure, thereby reducing fluctuations in output temperature.
