Fast Flo Valve - Hansen Fast Flow Valves

Inlet Size

Application:

Adding to the Hansen HiFlo family of valves comes the much anticipated release of the Hansen Fast-Flo valve. Ideally suited to tight fitting environments that demand a more compact sized valve with responsive on/off capabilities, the Fast-Flo valve brings with it exceptional flow rates and adaptability. 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.

Each valve is supplied with: Complete Plastic Valve Body, Brass Arm & Adaptors. Cord & Nuts supplied with Long Brass Arm Valve only.

    Features and Benefits:

    • For automatic filling & maintaining water levels in animal drinking troughs, water storage tanks & water cisterns etc
    • Small compact design suited to confined spaces ie small feeder bowls, troughs & header tanks
    • High performance, cost effective trough/tank valve - 29 psi, 34 l/min
    • The Fast~Flo Short Arm Valve has the highest flow of any valve of its size at 500 kPa (73 psi) it will deliver 56 l/min
    • Ability to attach a diffuse hose to reduce water turbulence & noise in top entry installations & Anti-Siphon Holes to prevent back flow.
    • Designed with an Ezi Bend brass arm to make water level adjustment a breeze
    • Will fit multiple thread & connection combinations 15 - 50mm
    • Reliable with high and low pressure applications from 0 - 12 bar
    • Durable urethane seat, which is reversible
    • Suitable for top or side entry
    • Manufactured from strong non corrosive UV stabilised materials

      Technical Information:

      • 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
      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 over tighten.
      • 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.

      • Place the ribbed side of the Rubber (soft) Washer against the hole inside the bowl/trough/tank. Insert the Long Tail Adaptor through the washer & inlet hole in the bowl/trough/tank wall.
      • On the outside, place the Poly (hard) Washer on the Long Tail Adaptor with the ribs facing the bowl/trough/tank wall. Thread on Adaptor 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.
    • Will the Hansen fast Flo valve work in my calf shed bowl troughs?
      Yes the 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.
      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 Fast Flo valve will the flow be any better?
      Yes the Fast Flo 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 Fast Flo valve work with high pressure?
      Yes the Fast Flo Fast Flo 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 Fast Flo valve use the same rubber seat?
      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 Fast Flo valve be any quieter?
      he noise while the tank is filling is caused by the high velocity of the water from the valve outlet into the tank. The Fast Flo 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 Fast Flo valve?
      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
