Minimix 3-way mixing valves

WITA® Minimix, Maximix and type “H” mixing valves are made of brass. The valves are sealed with two O-rings and can be easily connected to the SM4/SM44 actuators. Type “H” mixing valves are equipped with a bypass and can therefore be used in low-temperature heating systems. The product also has a flange, which allows the valve to be mounted directly on a pump.

The Compact Minimix 3- and 4-way mixing valves are designed for small and medium-sized central heating systems, while the Maximix valves are intended for medium and large systems. The valves can be operated manually or set automatically. Together with the SM 4.6 actuator (or SM 4.10 actuator) they form a compact unit. The body, bonnet, shaft and cone are made of brass. The linear characteristic of a temperature is achieved by using profiled outlet holes. Two EPDM O-rings seal the shaft. The 4-way mixing valve can be mounted on any side.
When mounting a valve with a distributor, it can be adjusted by 45°. The boiler supply is factory-set to the left.
The 3-way mixing valves are intended for straight flow paths. The return connection can be positioned on the right or left side and is factory-set to the left.
