Tempering valve for solar and instantaneous applications

2522HP series

Installation, commissioning and servicing instructions

The tempering valve is used to regulate the set

temperature of mixed hot and cold water even when

variations occur in the water supply conditions.

The Caleffi 2522HP series has been specifically

designed

and

manufactured

to

meet

the

requirements of

“AS 4032.2:2005 Tempering valves

and end-ofline temperature actuated devices”.

This particular series of tempering valves has been

developed primarily for installation in solar hot water

systems. These valves are also suitable for use on

instantaneous and general hot water storage systems.
