FREQUENTLY ASKED QUESTIONS
- QUESTION: At present I get valve bounce in my troughs, will the Max-Flo valve stop this?
- ANSWER: Yes, valve bounce is created from high flows at high pressures, because our Hansen Max-Flo valve delivers higher flows than other valves it will effectively reduce line pressure which in return will reduce the incidences of this problem by also reducing water hammer.
- QUESTION: At present I have noticed some shuddering and noise in my pipelines when my pump starts and stops, will your valve stop this?
- ANSWER: Yes, this is called water hammer, we have designed the Hansen Max-Flo Valve to open and close slower than other valves effectively varying the flows at these times to minimise the chance of water hammer.
- QUESTION: Can I use the Hansen Max-Flo Valve as a top entry valve with an air gap?
- ANSWER: Yes, the Hansen Max-Flo Valve can be installed at the top, side or bottom entry as all components come with each valve.
- 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. 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.
- 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 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 have problems with having to constantly clean my valves as my water supply can get dirty at times, how will the Hansen Max-Flo valve handle these conditions?
- ANSWER: Our patent pending “Self Cleaning Pilot” will increase durability and suitability in dirty water situations.
- QUESTION: I only irrigate from my tank at night and have a time 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 can’t keep up, resulting in more 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 much lower pressure e.g. 400kPa (58 psi) = 772 l/min (170 gpm).
- QUESTION: My rain water supply can get very dirty at times. Can the Rain Relief Valve cope with dirty water?
- ANSWER: Yes, both the Slo-Flo and Rapid-Flo Rain Relief Valves are designed to handle dirty water.
- QUESTION: My troughs have both 20mm & 25mm threaded inlets, does your Hansen Max-Flo Valve come in both sizes?
- ANSWER: Yes, the Hansen Max-Flo Valve comes with the required components to install in 20mm or 25mm threaded inlets. This of course means you only need to buy one valve for all sized inlets.
- QUESTION: What is the difference between the Rain Relief Valve and the Leveller Valve?
- ANSWER: The Leveller Valve opens when a pre-defined minimum water level is reached and will fill your entire tank. The Rain Relief Valve will only supplement your tank with either 50mm or 100mm of water, depending on the float orientation.
- QUESTION: What is the difference between the Slo-Flo Rain Relief Valve and the Rapid-Flo Rain Relief Valve?
- ANSWER: The Rapid-Flo and Slo-Flo Rain Relief Valves are essentially the same valve. The key difference between them is that the Rapid-Flo valve is capable of functioning at full flow rate whereas the Slo-Flo valve is restricted to 2 l/min to conform to the Sydney Water Guidelines.
- QUESTION: What pressure can I run my Hansen Max-Flo Valve at?
- ANSWER: The Hansen Max-Flo Valve will operate from 0.2 bar to 12 bar.
- QUESTION: Will the higher flow cost me more to run my pump?
- ANSWER: No, because the Hansen Super-Flo valve is more efficient than what you are used to. The reduced operating pressure required will equate to higher flows at lower pressures at your pump which in turn will reduce pumping time and cost.
