Optibal W6 Six-way ball valve
DN 20, G 1 with inner taper

Six port control valve for combined heating and cooling systems. For changeover between heating and cooling operation in four pipe systems, for example heat / chilled ceilings or fan coil units.
The six port control valve consists of two three port ball valves which are combined in one housing and operated by a common stem. It carries out the function of four two way valves and substantially reduces material and installation effort.
A fully closed zone is located between heating and cooling operation to ensure full separation of the two circuits. By a marking on the end of the stem the valve position can be determined, also when the actuator is removed. For optional fixing an M5 thread is located on the underside of the valve.

Valve size: DN20 (3/4”)
