Product Tabs

Overview

PRLG (Pressure Regulator Landscape Grade) is ideal for installations requiring lower flows of 0.5 to 7.0 gpm (114 to 1590 L/hr).

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

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.
