Description
Hansen Leveller Valve 32/40/50mm, High Performance Reservoir / HLEVELLERS
The Leveller Valve enables you to set a minimum and maximum water level when filling your tank with a pump.
This is supplied with Complete Valve Body, 32, 40 & 50mm Standard Adaptors, Leveller Control,
115mm Weighted HiViz Threaded Ball, 140mm Blue Threaded Float, 2.4 metre Cord.
The Hansen Leveller Valve has been designed for tank installations where a level differential is required to stop pumps and water systems cycling (continually switching on and off).
The new design features a float and weighted ball that enables the user to set the valve to open at the minimum fluid level and close at the maximum fluid level.
The Leveller Valve features the Hansen diaphragm configuration with “Self Cleaning Pilot” which has been designed for soft open and close thus reducing water hammer and increasing pump and water systems life expectancy.
The Leveller Valve has been designed to operate reliably in high and low pressures (0.2 bar – 12 bar) and in clean and dirty fluid conditions.

LEVELLER VALVE INSTALLATION INSTRUCTIONS (Refer to the visual instruction guide in image gallery)
- Step 1a: Measure the existing inlet thread to determine which size adaptor is required (example: 32mm, 40mm, 50mm)
- Step 1b: From the supplied adaptors choose the appropriate size.
- Step 2a: Screw selected adaptor into Leveller Valve Body (O-Ring facing
to body).
- Step 2b: Inspect inside of tank to determine if there is enough clearance to install assembled valve. If yes, go to step 6. If not, go to step 3.
- Step 3a: NOT ENOUGH CLEARANCE. Remove the Leveller Valve Orange nut, arm assembly & rubber diaphragm from valve.
- Step 3b: Screw Leveller Valve body into threaded inlet.
- Step 4a: Re-assemble Leveller Valve, insert rubber diaphragm into valve body.
- Step 4b: Guide Leveller Valve assembly into Leveller Valve body ensuring guide pin is in pilot hole. Do Not Puncture Diaphragm!
- Step 5a: Ensure leveller arm is hanging down in a vertical position and that valve body is horizontal to the tank wall.
- Step 5b: Tighten Orange Nut firmly!
- Step 6: Decide on Minimum and Maximum water levels. See step 9 for minimum level guidance before proceeding through this step. Screw blue float onto Leveller Valve Arm for OFF position. The float can be moved up and down the arm. This determines Maximum level of water.
- Step 7a: Screw cord nut into HiViz Weighted Ball
- Step 7b: Ensure the HiViz Weighted Ball is filled with water and not hindered by any obstructions.
- Step 8a: Thread the string through the end of arm hole, then tie off at cleat to set Minimum level.
- Step 8b: Remove excess string, leaving enough for future fine tuning.
- Step 9: NOTE: The HiViz Weighted Ball must be off the bottom of the tank and most importantly above tank outlet.
- Step 10a: Ensure valve is operating in open/closed position as required. NOTE: the Leveller arm may be in the closed position but the valve may take up to 8 seconds to fully close. Do not force arm closed.
- Step 10b: Fine tuning can be achieved by adjusting the Blue Float up and down the arm and adjusting the length of the string for the on position.

FREQUENTLY ASKED QUESTIONS
- QUESTION: I have noticed my pump switching
on and off rapidly at times, will your Leveller Valve stop this?- ANSWER: Yes, this is called cycling and can
drastically reduce the life of your pump. The Hansen Leveller Valve is designed to control your pump safely by eliminating pump cycling and providing an adjustable water differential depth in your tank.
- QUESTION: I only irrigate from my tank at night
and have a timer on my bore pump. It will only fill my tank at night when I’m irrigating but I still find my bore pump is cycling when I’m irrigating. Will the Hansen Leveller Valve help in this situation?- ANSWER: Yes, you will find the reservoir valve
you are using at the moment is only supplying a flow close to your irrigation demand, with the Hansen Leveller Valve the flow delivery will be much higher and will allow your bore pump to run for less
time as well as setting a differential in the tank to enable your pump to shut off for sensible periods.
- QUESTION: In my dairy shed at peak water
demand times I find my pump is cycling. As demand increases they run continuously and often cannot keep up, resulting in no water in
troughs and other areas in my shed. Will your Leveller Valve fix this issue?- ANSWER: Yes, as long as your pumps are sized
correctly to cover your peak demand the Hansen Leveller Valve will help by delivering a much higher flow at a much lower pressure e.g. 400kPa (58 psi) = 772 l/min (170 gpm).
- QUESTION: For years now I have had problems
with filling my tanks as my water supply can get very dirty at times. I believe I have purchased every valve on the market and all have let me down at some point, will the Hansen Leveller Valve finally fix my problem?- ANSWER: Yes, our range of HiFlo Valves are
designed to handle dirty water. With the Hansen Leveller Valve which is based on our diaphragm valves it is unique in that it has a pin that cleans the pilot hole in the diaphragm every time it opens and closes. In addition to that the gap between the diaphragm and the valve body when open is a huge 14mm further reducing potential blockages.
