Valve maintains fluid level in various applications, replacing ball float valves. Internal parts are made of ABS plastic, EPDM rubber & stainless steel.
Fluid level forces 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 valve is resilient to freezing.
