Pressure Reducing Station

Pressure Reducing Station

Pressure Reducing Station

(OP)
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.

RE: Pressure Reducing Station

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

RE: Pressure Reducing Station

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.
