It is an inlet pressure-regulating valve and responds to changes to inlet pressure (condensing pressure) only. A decrease in condensing pressure causes less pressure to act on the bottom of the seat ...

Typical fan cycle control setpoints. [Editor's note: This is the second installment of a two-part series on head pressure control.] In part 1 of this article, on the fundamentals of head pressure ...

Pressure regulators, more commonly known as pressure-reducing valves, keep the output pressure constant in compressed-air systems no matter how the input pressure or output flow changes. They ...

Normally, it should not exceed 60 psi. The pressure regulator is usually preset to 50 psi. However, it can be adjusted anywhere from 25 to 75 psi with a simple turn of a screw, as shown above.

A mathematical model for a two-stage pressure reducing valve connected to a constant pressure supply circuit and a resistance type hydraulic load has been developed. This model can be used for ...
