Asahi Butterfly Valves from HMA Flow & Industrial feature an improved sealing performance due to a patent-pending special seat design. The required operating torque has been lowered as a result. The valve body protects against over-tightening, in order to avoid breakage or seat deformation.

A spherical design disc provides superior durability and improved Cv value. A stem retainer allows for field automation or accessories, without the stem having to be removed. A newly-developed, corrosion-resistant gearbox covers a broader range of applications.
