Description
Hansen Fastflo Short Brass Arm with 15mm Long Tail Adaptor / HFFSV15LS
This is supplied with: Complete Plastic Valve Body, Short Brass Arm & 25mm Long Tail Adaptor
Adding to the Hansen HiFlo family of valves comes the much anticipated release of the Hansen Fastflo valve.
Ideally suited to tight fitting environments that demand a more compact sized valve with responsive on/off capabilities, the Fastflo valve brings with it exceptional flow rates and adaptability.
Built 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.

- FAST FLO SIDE ENTRY
- SIDE ENTRY TROUGH/TANK (See visual guide in image gallery)
- Place the rubber washer on the long tail adaptor with ribs facing out so that the sealing surface is against the trough/tank wall when adaptor is put through inlet hole.

FREQUENTLY ASKED QUESTIONS
- QUESTION: 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?
- ANSWER: Yes, the Fastflo valve has the highest flow of any valve in its class/size. At 500 kPa (73psi) it will deliver 56 l/min.
- QUESTION: I have a header tank in my house that is very noisy while filling, will the Hansen Fast-Flo valve be any quieter?
- ANSWER: The noise while the tank is filling is caused by the high velocity of the water from the valve outlet into the tank. The Fastflo 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.
- QUESTION: I have found the rubber seats in the compact trough valves I am using don’t last very long, does the Hansen Fastflo valve use the same rubber seat?
- ANSWER: 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.
- QUESTION: 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 Fastflo Valve work with high pressure.
- ANSWER: Yes, the Fastflo Valve has the arm pivot point positioned to allow closing at pressures up to 12 bar (174psi) with a 115mm float attached.
- QUESTION: What size tank inlet do I need to fit the Hansen Fastflo Valve?
- ANSWER: All 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 weak point in other brands of valves.
- QUESTION: Will the Hansen Fastflo Valve work in my calf shed bowl troughs?
- ANSWER: Yes, the Fastflo was designed as a compact valve for use in small bowls, compact troughs, feeders & header tanks or any situation where the valve space is confined.
