What it is

The Altecnic 533 3 Bar 4.75 Bar SRV Unvented Kit is an unvented control valve kit from Altecnic, supplied as part number 533004. It sits within the Altecnic unvented control valves range and carries 3 bar and 4.75 bar settings for the pressure and relief functions of an unvented hot water installation. It is fitted as part of the cylinder's control valve arrangement.

Signs this part needs replacing

  • Water discharging from the expansion relief valve or tundish when the cylinder is heating normally
  • Inlet pressure at outlets sitting above the regulated level rather than holding steady
  • Weeping or drips from the valve body or its connections
  • Pressure fluctuation at taps and outlets as the cylinder heats up
  • Banging or noise in the pipework linked to uncontrolled inlet pressure

Before you order

  • Confirm the existing valve is the Altecnic 533 series and matches part number 533004
  • Check the cylinder manufacturer's required pressure and relief settings against the 3 bar and 4.75 bar figures
  • Check the pipework connections and access on the existing installation before removal
  • Confirm whether a service kit is the correct route rather than a complete valve
