Hansen Fast Flo Trough / Tank Valve Long Arm Pack

$33.06

The Hansen Fast Flo Valve is ideally suited to tight fitting environments that demand a more compact sized valve with responsive on / off capabilities, exceptional flow rates and adaptability. The Fast Flo allows a hose attachment to both diffuse and help eliminate noise from the outlet flow and has a tough, reversible, urethane seat which effectively doubles the life of the valve providing a ‘best of class’ valve that’s reliable for the long term.

FF-Flow-Graph Hands_Assembling

Trough / Tank Installation:

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

FF_Side_Entry

TO CHANGE WATER LEVEL

Adjust the length of the cord at the top of the float. Use the nut & cord on the long arm valve only.

Side Entry Trough/Tank:

  • Place the ribbed side of the Rubber (soft) Washer against the hole inside the trough/tank. Insert the Long Tail Adaptor through the washer & inlet hole in the trough/tank wall.
  • On the outside, place the Poly (hard) Washer on the Long Tail Adaptor with the ribs facing the trough/tank wall. Thread on Adaptor Nut and tighten firmly. Do not overtighten.
  • Screw the Cord Nut* onto the Fast~Flo Brass arm.
  • Thread the Cord* through the Fast~Flo Float. Tie the Cord off to achieve the correct water level.

*Cord and Nuts only supplied with long arm version.

FF_Top_Entry

NOTE: If an existing or moulded threaded inlet in the trough or tank uses a Hansen Standard Adaptor.

Top Entry Trough/Tank

  • Place the ribbed side of the Rubber (soft) Washer against the hole inside the trough/tank. Insert the Long Tail Adaptor through the washer & inlet hole in the trough/tank wall.
  • On the outside, place the Poly (hard) Washer on the Long Tail Adaptor with the ribs facing the trough/tank wall. Thread on Adaptor Nut and tighten firmly. Do not overtighten.
  • Screw the Fast~Flo Float onto the Brass Arm, do not bend Brass Arm.
Will the Hansen valve work in my calf shed bowl troughs? Expand

Yes the valve was designed as a compact valve for use in small troughs and header tanks or any situation where the valve space is confined.

I have a compact float valve in a header tank, the flow is too low into the tank and won’t keep up with our requirements. I can’t fit a larger valve into this tank, if I replace it with a Hansen valve will the flow be any better? Expand

Yes the valve has the highest flow of any valve in its class/size. At 500 kPa (73 psi) it will deliver 55 lpm.

The pressure at my header tank is quite high and the compact float valves I have used either don’t last very long or they don’t shut off properly and I find the overflow running. Will the Hansen valve work with high pressure? Expand

Yes the valve has the arm pivot point positioned to allow closing at pressures up to 12bar (174psi) with a 115mm float attached.

I have found the rubber seats in the compact float valves I am using don’t last very long, does the Hansen valve use the same rubber seat? Expand

No the seat we use in all Hansen piston type float valves are urethane which is a very durable and hard material. The seal is also reversible if a foreign body should damage it.

I have a header tank in my house that is very noisy while filling, will the Hansen valve be any quieter? Expand

The noise while the tank is filling is caused by the high velocity of the water from the valve outlet into the tank. The valve outlet doubles as a spigot so you can attach a length of hose to allow the flow to be placed onto the bottom of the tank eliminating this noise.

What size tank inlet do I need to fit the Hansen valve? Expand

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 adaptors. The additional material used at the inlet to form the female thread strengthens the valve at an area that has been identified as a week point in other brand valves.
