SKU: N/A Category:


High Flow trough valves are float operated valves for use in automatic filling of water troughs, tanks, cisterns etc.  The valve is configured for above or below water mounting. The float operates a small pilot valve which in turn operates the main diaphragm valve. Trough valves are a good choice where their high flow, compact, robust, non corrosive construction and high level of adaptability are needed.

Popular uses include maintaining water levels in:

  • Animal drinking troughs
  • Water storage tanks
  • Water cisterns
  • Air conditioning systems
