The TWO LEVEL FLOAT VALVEs are designed for controlling Agricultural/Farm Water, the water working in conjunction with a farm type pump/pressure unit and used to the water level in a storage tank which is being supplied by a pump or pressure unit.
They are NOT SUITABLE for commercial buildings or industrial use or forconnecting to City/Town Water Mains Supply.
Alderdice Foot Valves are made of Gunmetal Bronze. They have a nitrile faced valve giving a positive non-return seal. The barrel-shaped body allows an easy flow around the valve.
It allows a drop of 400 mm in the water level of the storage tank before the valve opens, it then holds Fully Open until the water reaches the “full” level of the tank, then SHUTS OFF INSTANTANEOUSLY, so eliminating the constant cycling of the pump, reducing wear and saving power.
This valve is made in 11/4” pipe size, is suitable for all pressures up to 100 p.s.i.(700 KPA), and will deliver approx. 3000 gallons per hour at 45 p.s.i. (230 Lt/per minute 300 KPA).
Galvanised Pipe/Brass/Copper Supply Pipe (Not P.V.C. Pipe) must be Horizontal (Level) Checked With Spirit Level and securely attached to side of tank projecting 300 mm into tank. If tank has a coverthen the centre of the supply pipe must be at least 150mm down from top of tank.
Flow rate discharge from the Float Valve should not exceed 230 L/M (3000 Gals Per Hour).If necessary the flow should be reduced by fitting a gate valve before the float valve so as toregulate the discharge flow down to 230 L/M
FOR CONTROLLING WATER ONLY. NO OTHER LIQUIDS.
