Hudson Valve maintains fluid level in various applications, replacing ball float valves.

The Hudson Valve is a Damage-Proof Automatic Valve Used for Fluid Control.

This 1/2" universal Hudson Valve maintains fluid levels in various applications, replacing ball float valves. The Hudson Valve's internal parts are made of ABS plastic, EPDM rubber & stainless steel. Fluid levels force a float to rise and close the diaphragm chamber as the diaphragm expands to stop the incoming flow. When the fluid level drops, the diaphragm escape is opened and allows the fluid to fill the tank. The Hudson Valve is resistant to freezing.

We also carry the 1/2" Hudson Valve Repair Kit (#120009).
