PR Pressure Regulators

Advantages:

Higher Flow Rates with Less Pressure Loss than competitive regulators!
Automatically regulates and prevents downstream pressure from exceeding its set point.
Wide range of adjustable settings from 5 to 75 PSI (0.35 to 5.17 bar).
Rugged construction with inlet pressure to 150 PSI (10.34 bar).
Rolling diaphragm design assures sensitive operation.
Non-sticking design.
One piece body eliminates internal leakage.

*Pressure Drop () is measured from set pressure of regulators

NOTE: The generally accepted safe velocity in plastic piping is 5 feet per second. The above flows go beyond this rate.

Plastic pressure regulators are multi-functional, normally-open valves for controlling downstream pressure, enhancing system performance, and balancing pressure in a process system.

For filtration applications, Plast-O-Matic Differential Pressure Regulators balance inlet and outlet pressure across a series of filters or other sensitive components.

Available in PVC, Kynar® PVDF, Natural Polypropylene, Teflon®, sizes 1/4" to 3" NPT. Ideal for corrosive and other chemical process, as well as deionized water, reverse osmosis water....any ultra-pure liquid.

Plast-O-Matic regulators deliver higher flow and much less drop-off from set pressure than other typical pressure regulators. Operation is smooth, sensitive and extremely accurate.
