MZ
Satchwell MZ valves are suitable for a wide range of applications, such
as heating, cooling, air handling and domestic hot water systems. These
valves have a linear moving spindle and a modified parabolic characterised
plug operating against the upper seat, which controls flow quantity to suit
the load. The lower part of the plug has a linear characteristic operating
against the lower seat, and controlling the bypass quantity.
MZ valves can also be used with a medium of max. 25% glycol solution.
