The Hudson Valve's unique design maintains fluid level in various applications replacing other kinds of valves. The valve operates an exceptional patented float system.The valve operates using a float and a control diaphragm chamber. When hooked up to a water source the valve will allow water to flow through it until the water reaches the bottom of the valve. As the water level rises it causes the float inside of the valve to rise allowing the diaphragm chamber to fill and close the valve.

• Applications: The Hudson Valve is designed to be used in water. For Aquariums, Car Washes, Evaporative Coolers, Fountains, Holding Tanks, Irrigation Systems, Landscaping, Livestock Tank, Ponds, Swimming Pools....and more
• Construction: Valve body is durable glass-filed nylon and the internal parts are of ABS plastic, silicone and stainless steel.
• Connection: V-1/2" = 1/2" female pipe thread and V-1 = 1" female pipe thread
• Minimum Inlet Pipe Size: For the ½” Valve no smaller than ¼” and no bigger than 1”. For the 1” Valve – no smaller than ½” and no bigger than 2”
• Height: V-1/2 and V-1 = 5.0"
• Diameter: V-1/2 = 3.0" and V-1 = 3.75"
• Operating Pressure: 8 to 140 PSI
• Flow Rate: 80% of flow supplied to valve
• Shut-off Height: The valve will shut of about 1 ½”- 2” up from the bottom of the valve depending on pressure (the higher your water pressure the higher up on the valve the water will shut off). There will be a short delay in shut-off the first time the valve is used while the control chamber fills with water.
• Max Temperature: 90 F
• Anti-siphon requirements: When properly installed the valve meets anti-siphon requirements.
