Flowserve-Worcester Valve 4446PMSE.100 1 Inch Npt Carbonsteel Ss Ball Valve

The Flowserve-Worcester Valve 4446PMSE.100 is a three-piece floating ball valve composed of carbon steel with a stainless steel ball and a 1-inch NPT thread. It is a quarter-turn shutoff valve, which means that turning the handle 90 degrees will fully open or close the valve. Boilers, chillers, and pipe systems are just a few examples of the HVAC (heating, ventilation, and air conditioning) equipment that frequently uses this valve. The valve functions by use of an internal hollow ball within the body that has a hole in the middle. By turning the handle, fluid can travel through the ball's hole since it is aligned with the flow channel. The ball's hole is plugged and the flow is halted when the handle is positioned perpendicular to the flow route.
