Mainly used for controlling the bypass of incoming water in water treatment systems.

Suitable for use with F65, F69, and other Runxin control valves.

When the water softening system requires maintenance, the bypass function of the bypass valve can be used to supplement untreated raw water to the outlet.

When used in domestic water softening systems, since very soft water is not suitable for drinking, the bypass valve can be used to mix some untreated raw water directly from the outlet with softened water to increase the hardness of the water output.When used in domestic water softening systems, due to the unsuitable nature of very soft water for drinking, the bypass valve can be used to mix some untreated raw water directly from the outlet with softened water to increase the water hardness.
