The Leafield A6 PRV is a well tested low profile pressure relief valve. Increasingly fitted by manufacturers to RIB and inflatable boat tubes, river rafts and life liferafts to prevent damage from the air pressure building up due to heat from the sun. These can be retro-fitted to tubes by using the appropriate Hypalon or PVC doubler and adhesive available from RIBstore.
  • Very smooth low profile.
  • Available with relief pressures of 0.5psi to 20.0psi
  • Rugged and Reliable.
  • Materials used have high UV resistance.
  • Protects the structure from over inflation and excess pressure build up due to solar heat.
  • 100% tested for opening and closing pressures.
  • High flow for size.
  • Approved to ISO 9650 and ISO 15738 as a transfer valve.
  • Rapid installation with clamp fitting – no welding or adhesive required.
  • –30ºC to +65ºC operating temperature.
  • Easy removal if necessary for cleaning.
  • Available in black, grey or white.
  • Install using the A6/C7/D7 spanner or A6/B7 spanner.
  • Filter caps available to stop debris entering the valve, without affect the pressure relief function.
  • Plug caps available for test purposes (to prevent the pressure relief function working).
