Product Tabs

Overview

The PRU (Pressure Regulator Ultra) was designed to handle higher flows of 20 to 100 gpm (4543 - 22713 L/hr). Its 2-inch inlet and outlet size make it an ideal option for accurate zone and individual sprinkler pressure control. Its compact size fits in a valve box.

Features

100% pressure tested, to ensure quality and performance
Very low hysteresis and friction loss
Large flow path resists plugging
Connections: 2" F NPT x 2" F NPT or 2" F BSPT x 2" F BSPT models available
Corrosion resistant
Two-year warranty on materials, workmanship and performance
