installation

In any position except for the "steering wheel down" position. The flow direction must match the arrow on the housing.

Before installing the valve, the internal cavities of the system, the pipeline must be cleaned of dirt, sand, scale and other foreign particles in order to avoid damage to the surface of the seat and disc, which can lead to a violation of the tightness of the valve.
