428-01 & 628-01
Modulating Float Valve
Cla-Val 428-01 and 628-01 Float Valves modulate to maintain a constant liquid level in a storage tank by compensating for variations in supply or demand. They can be installed to control the flow into or out of the tank by either closing on a rising level or opening on a rising level. These valves are hydraulically operated, pilot controlled diaphragm valves.
