Watts float valves are ideal for monitoring elevation changes in liquid-free surfaces and controlling high capacity water flow. They feature bronze construction, with flange structure on the inlet side providing support against tank walls and a male straight pipe threaded outlet for positive lockout. They come equipped with serrated arms for easy adjustment of water level and pivot assembly to prevent breakage during freezing. Choose from an extensive range of bulkhead-mounted float valves, available in 1/2, 3/4 and 3/8 inch sizes on Raptor Supplies.
