Megaflow trough valve


Mega flow trough valves are float operated valves for use in automatic filling of water troughs. The valve is configured for underwater mounting only. The float is connected to the valve with a nylon cord, this operates a pilot valve, when the water level drops, the pilot valve is opened and the main diaphragm valve is activated. Mega flow is a good choice where its high flow, compact, robust, non corrosive construction is beneficial.


Maintaining water levels in:

• Animal drinking troughs
• Water storage tanks


  • High flow
  • Compact robust construction
  • 20-60mm (3⁄4” – 21⁄2”) water level differential (increases as water pressure increases)
  • Positive on/off operation
  • Lock off with cord lock
  • 0.3 – 10 bar (5 – 150 P.S.I.) pressure rating
  • Inlet filter
  • Constructed from corrosion resistant materials
  • Under water installation helps avoid freezing
  • Valve is less prone to stock damage
