Product Tabs

Overview

The PRL (Pressure Regulator Low Flow) is ideal for installations requiring lower flows of 0.5 to 8.0 gpm (114 to 1817 L/hr). Suggested use in solid-set, drip, and other low-volume irrigation systems, as well as center pivot and mechanical-move irrigation systems.

Features

Senninger irrigation water pressure regulators maintain a constant preset outlet pressure with varying inlet pressures, which alleviates pressure differences that can cause an applicator’s area of coverage to change.
100% pressure tested, to ensure quality and performance
Very low hysteresis and friction losses
Can be installed above or below ground
Patented tamper-proof design
No external metal parts for excellent corrosion resistance
Two-year warranty on materials, workmanship and performance

Advanced Features

SennREG App

SennREG is a handy tool to bring into the field when checking your pressure regulator’s performance. With just a few clicks, you’ll know exactly what to expect out of your pressure regulator – from what your output pressure should be, to when you should start thinking about replacements.
