Product Tabs

Overview

Pressure Regulating Limit Valves are designed to be used in place of standard water pressure regulators to limit static (no flow) water pressure when a shut-off valve is used downstream from the regulation point.

Features

Senninger 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.
Limits downstream pressure to no more than 15 psi (1,03 bar) above regulated pressure rating during static (no flow) conditions
100% pressure tested, to ensure quality and performance
Very low hysteresis and friction losses
One-year warranty on materials and workmanship

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.
