Hudson Valve


Construction: Valve body is durable glass-filed nylon and the internal parts are of ABS plastic, silicone and stainless steel.

Connection: 1” FNPT (female pipe thread) Height: 5.0” Diameter: 3.75” Operating Pressure: 8 to 140 PSI Flow Rate: 80% of flow supplied to valve Max Temperature: 150° F Anti-siphon requirements: When properly installed the valve meets anti-siphon requirements.

OPERATION:The fluid level forces the float to rise and close the diaphragm chamber. The diaphragm then expands to stop the incoming flow. When the fluid level drops, the diaphragm escape is opened. The diaphragm empties and allows the fluid to fill the tank. This positive shut-off feature allows full flow until the valve closes, unlike common ball float valves which constrict the flow as the fluid level rises.
