Hansen Max-Flo Diaphragm Valves have been designed with multiple thread and connection combinations to increase overall durability and versatility. The patent pending “Self Cleaning Pilot” ensures the valves are durable and suitable for dirty water applications. Less operating pressure is required, reducing pumping costs and increasing flow. Mini body design allows for easy installation across a wide range of applications and our 30 year time tested performance slow open and close diaphragm ensures no undue stress is placed on pump lines or pumps.

Hansen Max-Flo Trough & Tank Diaphragm Valves – Product Features

  • Top Entry Installations – Screw the adjustable float to the arm of the Maxflo valve. Adjust the mounting position to achieve the desired air gap between the threaded valve body outlet and the water level. Air Gap is adjustable from -19mm to +45mm @ 3.5 bar.

  • Side and Bottom Entry Installations – Thread the cord through the valve body arm then through the float mounting hole and around the float to the top hole. Water level height is changed by adjusting the cord length from the top and tying off on the hole.

  • Slow Close Action – The Maxflo internals have been designed with a built in delay in closing, this helps to minimise water hammer. NOTE: The Maxflo arm may be in the close position but the valve may take up to 8 seconds to fully close. Do Not Force Float Arm.

  • Self Flushing Pilot Hole – Hansen Max-Flo Valves have been designed to ensure reliable operation at low and high pressures.  NOTE: Pressurised water will pass through the pilot hole and over the arm when opening and closing. Water will stop passing through the pilot hole when fully closed.

  • Anti-Syphon Holes – When the valve body outlet is submerged in water or has an extension outlet tube attached, the Anti-Syphon Holes have been designed to be knocked out to prevent the valve from back flowing as long as the Anti-Syphon Holes are above water level.

  • Extension Arm – Hansen Max-Flo Valves include an Extension Arm. Use this Arm when a larger air gap is required between the water and threaded outlet of the valve body. Air Gap is adjustable from +65mm to +105mm @ 3.5bar.

  • Male Adaptors – O-Ring seal short adaptors available in 15-50mm and long adaptors from 15-32mm. Manufactured from High Quality Glass Fibre Reinforced Nylon for a weather, termite, fungi & bacteria resistance.

  • Cleat – The Cleat is to lock the valve on or off when using a float with a cord.
