Introduction

Figure 1. 299 Series Commercial/Industrial Regulator

The 299 Series is a high capacity, pressure control regulator which uses a pilot to keep outlet pressure constant despite varying flow rates and inlet pressures. This lightweight yet dependable regulator is used for applications from large commercial sites to smaller multidwelling establishments.

This is not an adaptation of existing regulator design; it is an all new design of integrated cases and internal registration ports. The 299 Series is available with optional external registration for extremely accurate outlet control, a 2-inch flanged body, and cast iron or steel body material.
