The Heatrae Sadia Megaflo 10bar temperature and pressure relief valve is a critical safety component engineered to control pressure build-up within closed unvented heating systems. Designed to relieve excess thermal expansion and prevent potentially dangerous hydraulic overpressure, this 0.25kg valve ensures the structural integrity of the associated cylinder and surrounding pipework. The robust brass construction and precision-engineered internal mechanisms deliver reliable discharge functionality under extreme operational conditions, making it an essential replacement part for comprehensive system maintenance.

This versatile relief valve features a highly efficient push-fit inlet connection paired with a male screw-fit outlet, significantly reducing installation time for mechanical contractors in confined utility cupboards. It is fully compatible with an extensive array of unvented hot water storage solutions including the Megaflo Eco, Premier Plus ErP and CenterStore series. The compact 230mm by 90mm footprint allows for straightforward retrofitting into existing heat interface units and complex unvented cylinder arrays.
