Fixed Pressure Regulator

Have you experienced a problem with excessive foaming when filling spray bottles or mop buckets? The root of the problem is usually water pressure in excess of 60 PSI (Dynamic). Knight recomments that you install a low cost fixed pressure regulator to control the water pressure at a maximum of 40 - 50 PSI. High water pressures can also vary the ratios and flow rates of the proportioner; so installing the fixed pressure regulator is key for optimum proportioner performance.

Knight’s fixed pressure regulator is 3/4 MNPT x 3/4 FGHT, which provides a quick and easy installation. Below is an example of a typcial installation:

The Knight part number for the fixed pressure regulator is 7407117. We recommend keeping a few in stock for high pressure installations.
