Pneumatic pressure regulators are designed to provide a constant pressure output from a fluctuating supply pressure – much the way an electronic voltage regulator works. Pressure regulators provide varying degrees of accuracy with regard to their reduced pressure output. General Purpose pressure regulators work for most fluid power applications. However, for more pressure-critical applications precision regulators can provide the customer with the control they need.
A partial listing of things that can potentially cause regulator output pressure variation are:
• Temperature changes
• Inlet pressure changes
• Variations in flow
• Excess downstream pressure
