Fastflo Long Brass Arm with 20mm & 25mm Standard Adaptors
Product
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 (73psi) it will deliver 56 l/min
I have a header tank in my house that is very noisy while filling, will the Hansen Fast-Flo valve be any quieter?
The 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.
I have found the rubber seats in the compact trough 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 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.
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 Valve has the arm pivot point positioned to allow closing at pressures up to 12 bar (174psi) with a 115mm float attached.
What size tank inlet do I need to fit the Hansen Fast-Flo Valve?
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.
Will the Hansen Fast-Flo valve work in my calf shed bowl troughs?
Yes, the Fast-Flo 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.
