Ultra Compact, High performance valve ideally suited to very tight spaces


Ideally suited to tight fitting environments such as small bowls, feeders, portable troughs and header tanks that demand a more compact sized valve. With responsive on/off capabilities, the Mini Fast Flo valve is build to the same quality and precision specifications as the Hansen range of valves that precede it,  the barbed outlet allows for a hose attachment to both diffuse and help eliminate noise from the outlet flow. A tough, reversible urethane seat effectively doubles the life of the valve providing a 'best of class' valve that's reliable for the long term.

Installation Guide:

  • Flush pipe lines into water tank or troughs before installing Mini Fast~Flo Valve into new system
  • Isolate the water going to the bowl, trough or tank to replace valve in an existing system.
  • Thread O-Ring end of correct size Long Tail Adaptor into Mini Fast~Flo Valve Body and tighten firmly enough that the O-Ring creates a seal against the Mini Fast~Flo Valve Body face. Do not over tighten

  • Place the ribbed side of the Rubber (soft) Washer against the hole inside the bowl/trough/tank. Insert the Long Tail Adapter through the washer & inlet hole in the bowl/trough/tank wall.
  • On the outside, place the Poly (hard) Washer on the Long Tail Adapter with the ribs facing the bowl/trough/tank wall. Thread on Adapter Nut and tighten firmly. Do not over tighten.
  • Screw the Mini Fast˜Flo Float onto the Arm and use the Ezy Clamp to move the float to desired position for a water level that suits your requirements.


Q - Will the Hansen Mini Fast Flo valve work in my calf shed bowl troughs?
A - Yes the Mini Fast Flo valve was designed as a compact valve for use in small troughs and header tanks or any situation where the valve space is confined.

Q - The pressure at my compact trough’s is quite high and the compact float valves I have used either don’t last very long or they don off properly. Will the Hansen Mini Fast Flo valve work with high pressure?
A - Yes the Mini Fast Flo valve has the arm pivot point positioned to allow closing at pressures up to 12 bar (174 psi). 

Q - I have found the rubber seats in the compact float valves I am using don’t last very long, does the Hansen Mini Fast FloMini Fast Flo valve use the same rubber seat?
A - No, the seat we use in Hansen float valves are urethane which is a very durable and hard material. The seal is also reversible if a foreign body should damage it. 

Q - I have a header tank in my house that is very noisy while filling, will the Hansen Mini Fast Flo valve be any quieter?
A - The noise while the tank is filling is caused by the high velocity of the water from the valve outlet into the tank. The Mini Fast Flo valve outlet doubles as a spigot so you can attach a length of hose to allow the flow to be placed onto thetom of the tank eliminating this noise.

Q - What size tank inlet do I need to fit the Hansen Mini Fast Flo valve?
A - All the Hansen float valves carry a 25mm (1”) female thread on the valve inlet. This gives you a couple of benefits. The valve will fit inlets from 15mm to 50mm when using our range of adapters. The additional material used at the inlet to form the female thread strengthens the valve at an area that has been identified as a weak point in other brands of valves.
