Asahi Ball Valves from HMA Flow & Industrial boasts a new integral moulded top flange. The Asahi Type 21 can be converted easily from manual to automatic, without having to replace the body itself. A new bottom stand with an insert hole allows the valve to be secured to a bench or panel by simply using a metallic insert.

The stem of the Asahi Ball Valves from HMA Flow & Industrial use a double O-ring sealing arrangement for improved durability and sealing performance. The upper O-ring groove is deeper than the lower. Due to this design, the stem breaks first at the upper O-ring groove, acting as a back-up groove. Valve disassembly is simplified due to the handle being removed, and placing the raised lugs in the carrier.
