25x40mm Long Tail Adaptor with O-Ring Seal

Yes, both the Slo-Flo and Rapid-Flo Rain Relief Valves are designed to handle dirty water.

Yes, the Hansen Super-Flo Valve comes with the required components to install in 20mm or 25mm threaded inlets. This of course means you only need to buy one valve for all sized inlets.

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.

The Leveller Valve opens when a pre-defined minimum water level is reached and will fill your entire tank. The Rain Relief Valve will only supplement your tank with either 50mm or 100mm of water, depending on the float orientation.

The Hansen Max-Flo Valve will operate from 0.2 bar to 12 bar.

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.

Hansen have tested all its products for use with cold water up to a maximum temperature of 60°C (140°F). We do not recommend the use of these products with temperatures higher than 60°C (140°F) as plastic expands due to temperature increases. Hansen cannot guarantee the products will perform when used with temperatures over 60°C (140°F). Hansen products that have failed in temperatures higher than 60°C (140°F) will not be covered by our limited lifetime warranty.

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.

No, because the Hansen Super-Flo valve is more efficient than what you are used to. The reduced operating pressure required will equate to higher flows at lower pressures at your pump which in turn will reduce pumping time and cost.
