What it is

The Altecnic 533 manifold combines a 6 bar safety relief valve (SRV) and a 3.5 bar pressure reducing valve (PRV) within a single unvented control valve assembly. It forms part of the Altecnic unvented control valve range, regulating incoming mains pressure and providing over-pressure relief on unvented hot water systems. The part reference is 533003 CST.

Signs this part needs replacing

  • The pressure reducing valve no longer holds a steady outlet pressure
  • Discharge from the safety relief valve or tundish occurs with no other fault present
  • Continuous or frequent weeping from the relief valve
  • Downstream pressure drifting high or low against the set value
  • Visible scale, corrosion or damage at the manifold body or valve heads

Before you order

  • Confirm the appliance is an Altecnic unvented control valve installation
  • Check that the existing valve settings match a 6 bar SRV and 3.5 bar PRV
  • Verify the part reference 533003 CST against the manifold being replaced
  • Confirm access and orientation suit the existing pipework arrangement
