Merrill FRGX10300 1" x 2-3/4" Flow Control Valve 30 GPM

Overview

The Merrill FRGX10300 1" x 2-3/4" Flow Control Valve (30 GPM) is a precision-engineered plumbing component designed to regulate water flow in residential, agricultural, and commercial systems. Built for reliability and long-term performance, this flow regulator maintains consistent flow output even when system pressure fluctuates, helping protect downstream equipment and stabilizing system performance. Its durable construction makes it ideal for potable water systems operating below 180°F.

This valve delivers a nominal flow capacity of 30 GPM and requires a threshold pressure of 15–25 PSI for proper operation. It is designed for installations where predictable flow control is essential, such as well systems, irrigation setups, pressure-regulated distribution lines, and multi-fixture plumbing layouts. Compared to uncontrolled flow paths, a dedicated flow regulator provides tighter flow tolerance, helping ensure balanced water distribution and reduced stress on system components.

The Merrill FRGX10300 meets a flow tolerance of ±15% and is rated for systems operating at up to 200 PSI, making it suitable for a wide range of plumbing configurations. Its compact size and straightforward installation allow technicians and installers to integrate it easily into existing piping. By stabilizing flow under varying demand and pressure conditions, this valve supports long-tail system reliability and improved overall hydraulic performance.
