427-01 & 627-01
Modulating Float Valve
Cla-Val Models 427-01 and 627-01 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 either 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.
