Asahi AV Ball Valve 21 Type, 21 Alpha Type Socket Type

-The new mechanism with a top flange makes it easy to change from a manual valve to an automatic valve. - Equipped with a bottom stand, it can be easily fixed to a gantry, panel, etc. - Durability and sealability are improved by adopting a double O-ring for the stem. Also, since the upper O-ring groove is designed deeper than the lower O-ring groove, Even if the stem breaks, the groove at the top breaks first and there is no leakage of liquid inside. Since the handle also serves as a fastening jig, a convenient fastening jig can be obtained by engaging the protrusion on the upper part of the handle with the recess of the union.
