Series MK DN flanged, three-way shut-off valves can be used as shunt, mixing and on/off valves in heating, air conditioning and ventilation systems. Series MK DN three-way shut-off valves solve all the problems that installers encounter when they use traditional mixing valves. MK DN valve series can be motorized using MUT AS motor series and/or motors that are commercially available. Series MK DN three-way shut-off valves guarantee:
Extremely low flow-by even when used as shunt valves in systems with high differential pressures.
Equal percentage adjustment curves, the best for temperature control in heating and conditioning systems.
Impossible shut-off plug seizure even when calcium carbonate or other slag and deposits are present in the system
Operating temperature range from 4/110 DC.
These features make this valve highly suited to adjust temperatures in hot water production systems and to adjust temperatures in systems using structurally-embedded heating panels. Cast iron body, brass shut-off plug and stainless steel stem. Flanges are made according to UNI2223 and DIN 2533 standards. Stem seal is made using O-rings that are easily replaced in case of wear.
