They can be used in line to prevent water backflow or siphoning and have a very low cracking pressure.

Not suitable for use in marine sanitation systems.

  • High impact and tensile strength – “Water hammer safe” and insensitive to pressure shocks in the pipeline
  • Stainless spring – No corrosion issues or risk of internal valve staying open
  • Low cracking pressure – Minimal pressure required to open the valve with minimal restriction on flowrate
  • In line fitting – Minimal installation room needed and no other fittings required
  • Printed white arrow (opposite logo side) – Quick and easy identification of water flow direction
