Product Tabs

Overview

The PR-HF (Pressure Regulator High Flow) is ideal for installations requiring higher flows of 10 to 32 gpm (2271 to 7268 L/hr), including solid-set sprinkler and low volume manifolds.

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
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.

Regulator Comparison – Solid Set Models

Designed and Built to Rigorous Quality Standards
Senninger introduced the first in-line pressure regulator to the irrigation industry in 1966. Throughout the years, several models have been developed to meet a variety of installation needs. Today, Senninger pressure regulators are known worldwide for their accuracy and reliable performance.
