Watts 1000-01 Float Valve, Bronze, Flanged

The Watts 1000-01 is a 1" heavy-duty bronze lever-arm float valve that holds liquid level in cooling towers, refrigeration make-up lines and irrigation tanks. Its machined inlet flange mounts through a tank wall or bulkhead, and serrated long and short arms set the shut-off point. It ships without the float ball and rod, which are ordered separately. It features a bronze body and a buna-n seat. Rated to 165 psi and up to 180°F.

This 1 inch heavy duty mechanical float valve is used in commercial, industrial, and agricultural applications for controlling high capacity water flow and can be tank wall-mounted. It is ideal for use in air conditioning, refrigeration, and irrigation systems. This valve has a bronze body with a machine flange on the inlet side with 1 inch female NPT pipe threaded inlet connection and male straight-pipe threaded for locknut outlet connection. It has serrated arms for easy adjustment of water level, bronze long and short arms, replaceable seals, and no-jam single lever action. The short arm has 3/8-16 threads. The maximum pressure is 165 psi (11.4 bar).

Common Questions

Does this include the float ball and rod?

No. Watts bronze float valves ship without the float and rod; order an FLT-C (copper) or FLT-P (polyethylene) float and a 3/8"-16 rod separately.

Can I use it on drinking water?

No. This valve is not certified lead-free and is for non-potable service only — cooling tower and refrigeration make-up, irrigation, livestock watering and tank fill. Do not install it on a potable water supply.

How does it mount?

Through the tank wall: the machined inlet flange passes through the bulkhead and the straight-thread outlet takes a locknut and gasket to seal the penetration.

What size float and rod does it take?

The rod thread is 3/8"-16 on the whole bronze float valve line. Float diameter depends on the valve size and the shut-off level you need — check the Watts float valve catalog for the matching FLT-C or FLT-P float.
