Can I use the Hansen Valve as a top entry valve with an air gap?

Yes, the Hansen Valve can be installed at the top, side or bottom entry as all components come with each valve.

   
My troughs have both 20mm & 25mm threaded inlets. Does the Hansen Valve come in both sizes?
Yes each Hansen Valve comes with the required components to install in 20mm or 25mm threaded inlets. This of course means you only have to buy one valve for all sized inlets.
   
Will the higher flow cost me more to run my pump?
No, because the Hansen 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.
   
At present I get valve bounce in my troughs, will the Hansen Valve stop this?
Yes, valve bounce is created from high flows at high pressures, the Hansen Valve opens and closes slower than other valves so will reduce incidences of this problem.
   
I have problems with having to constantly clean my valves as my water supply can get dirty at times, how will your valve handle these conditions?
Our patent pending “Self Cleaning Pilot” will increase durability and suitability in dirty water situations.
   
At present I have noticed some shuddering & noise in my pipelines when my pump starts & stops, will your valve stop this?
Yes this is called water hammer, we have designed the Hansen Valve to open & close slower than other valves effectively varying the flows at these times to minimise the chance of water hammer.
   
What pressure can I run my Hansen Valve at?
The Hansen Valve will operate from 0.2bar to 12bar.
