Butterfly Valves

Seridium Butterfly valves comply with AWWA C-504 standard. This type of valve with soft rubber (Buna) seats is used in the water treatment industry. The AWWA valves can be used for throttling as well as open/close applications. The main features are a leak proof hermetic seal, easy installation and operation at the maximum differential pressure.

The soft Buna seats run the entire 360° of the disc, thus reducing turbulence and pressure drop. Butterfly valves are used in power generation, pollution control, the pulp and paper industry, water and waste water treatment facilities worldwide.
