Product Overview

The CLA-VAL 278-01: Constant Altitude Level Control Valve is typically designed for closed reservoirs where water is withdrawn through a separate line. This valve maintains a constant water level in closed tanks by compensating for variations in supply or demand. The desired water level is set by adjusting the spring force. The CLA-VAL 278-01 is designed for one-way flow only. It can be installed to control the flow into or out of the reservoir by closing on rising levels or opening on decreasing levels. It offers simple, reliable, and accurate operation, functioning completely automatically.
