Product Overview

The CLA-VAL 427-01 & 429-01/91: Modulating Float Level Control Valve is a self-stabilizing valve designed to maintain a constant liquid level. A slight change in liquid level moves the Float Control, prompting the main valve to seek a new position. As part of the CLA-VAL SERIES 420, this valve maintains a constant water level in a reservoir by compensating for variations in supply or demand. It can be installed to control the flow into or out of the reservoir by closing on rising levels or opening on decreasing levels. The CLA-VAL 429-01 is specifically designed for high-pressure system networks (P<16bar) and where tank levels change rapidly, recommended for 150 mm and less. These valves offer simple, reliable, and accurate operation, functioning completely automatically.
