Overview

The Senninger Mini Pressure Regulator (MPR) is an economical solution to help reduce excessive pressure. This helps reduce wind drift and overwatering throughout the irrigation zone, including changing elevations and long lateral runs.

Because pressure impacts flow, the MPR reduces flow fluctuations so that each sprinkler performs consistently and delivers the designed distribution pattern.

The MPR has a greater hydraulic area than most flow control devices, allowing pressure regulation over a wider flow range.

Features

Designed for use immediately beneath the sprinkler
Maintains the sprinkler's designed flow to +/-10% of nominal flow
Allows pressure regulation on sprinklers along laterals or mainlines with up to 115 ft (35m) elevation change
Connection: ½" M NPT inlet x ½" F NPT outlet
Models available: 15 psi (1.0 bar), 20 psi (1.4 bar), 30 psi (2.1 bar), and 40 psi (2.8 bar)
Senninger pressure regulators are available with models for a wide range of flows
Two-year warranty on materials, workmanship, and performance
