Xylem-Hoffman Specialty 601335 Float Ball Assembly

The Xylem-Hoffman Specialty 601335 Float Ball Assembly is an essential part of hydronic heating and cooling systems. It regulates water level and pressure by automatically opening and closing a valve. This spherical float rises and falls within a chamber as the water level changes. As the water level rises, the float ball activates the valve, preventing additional water flow. When the water level falls, the float ball opens the valve, allowing additional water to enter. This mechanism prevents system malfunctions and ensures peak performance by maintaining constant water pressure levels. As the water level rises, the ball causes a connected lever arm to open or close a valve that regulates water flow.
