Combating Droop in Self-Contained Pressure Regulators

From Jordan Valve Group
 

 
When qualifying valves for any pressure reduction application, there are several factors to consider. Initially, you must decide whether the application requires a control valve in order to be effective, or would a self-contained or piloted regulator be sufficient? In order to make this decision, you should consider: _ What is the pressure drop, or the difference between P1 and P2? _ What is the set point? _ Will there be large flow variations? _ How critical is the regulation/control? If it meets the design criteria, a regulator will prove a more cost effective means of pressure reduction in almost all cases. In addition to lower overall costs, a regulator offers other advantages, primary of which is fast response. This responsiveness is of great value when applied to non-compressible media, or in applications where delayed shut-off might blow a safety relief valve. Additionally, regulators are sensitive to load variations commonly seen when controlling heating or cooling pressures.
