Pressure Reducing Station

[cr1973]

Any online resources for pressure reducing stations?
I am curious as to how they work, and if they can reduce pressure to a set psi, or if it's just a set number of psi it takes off the head.

If you also use a PID with a pressure control valve, you can usually set any pressure your system allows at a particular point.

To my knowledge, they reduce pressure to a set psi. I've never heard of one taking a set amount of pressure head off.

In the most basic ones, a small diameter lateral line acts on a diaphram. The diaphram has a spring providing counter force. The operator sets the range of motion of this diaphram by adjusting the spring tension. The diaphram acts on a valve stem downstream. The valve opens or closes as needed, and provides increased or decreased pressure drop, as needed.
