4-way 6/4 Inch BSP Female DN40 Universal Mixing Valve Heating Cooling Systems

4-way valves are used with solid fuel boilers as mixing valves with simultaneous increase of the boiler return temperature. They can also be successfully used as regulating fittings in heating installations with cast iron boilers with oil or gas planes.

The new 4-way ARV rotary mixing valves with internal thread are made of brass. The connections are in the form of an octagon, which definitely simplifies installation with a hydraulic wrench. The valves are equipped with knobs for manual adjustment and angle of rotation limiters to facilitate the appropriate setting. The readable scale located on the knob cover enables precise reading of the valve opening degree. On one side there is a 0 to 10 scale, and on the other side there is a 10 to 0 scale. This allows the valve to work in various mounting positions. The thickened section of the circumference of the knob reflects the position of the valve inside the valve and it is made of non-slip material. To connect new ARV valves with new ARM actuators, elements made of durable plastic are located under the knob.
