ProtectoRiSE

Surge relief valve

The ProtectoRiSE is a highly recommended system component that is fitted at the top of the riser to prevent airlocks and sudden pressure changes due to power surges and other causes.

This triple-function, double-orifice air valve efficiently releases air to prevent pressure build-up and allows the ingress of air to prevent vacuum in the pipework. The ProtectoRiSE also provides a controlled bleed of air to maintain system stability.
