Product Specification

Additional Information



The Pressure Regulating Anti-Siphon Valve from Lafon ensures the smooth running of a pumping system connected to an above ground storage tank. This pressure regulating valve is designed to avoid accidentally emptying the tank by overloading the pump and delivery system, thereby limiting product loss and site pollution. Constructed from aluminium and copper-aluminium alloy with special hydrocarbon seals, the pressure regulating valve prevents head loss and regulates and stabilises the flow with no hammering effect. Thanks to their tri-flange connection, these pressure regulating valves can be removed and serviced without disturbing the installation’s pipework. Anti-Siphon Valve comes with:

  • Triangular 1 1/2” flanged connection
  • Fitted with a wire mesh filter
  • A maximum liquid column of 6m
  • The maximum flow rate is 83litres per min
  • Valve adjustment screw for adaption to the installation
