Product Details

Descrioption

Our API standard Butterfly Valve is commonly used for regulating the flow of liquids through them in an array of industries. This offered valve is expansively in demand and has garnered a huge clientele owing to economical pricing and customization of the whole range. This Full PTFE Buttefly Valves are widely used not only in petroleum, gas, chemical, water treatment and other general industries, but also in cooling water system of thermal power station.


Features

-One piece wafer and lugged body for strength and stability in extreme environments.

-PTFE and elastomer are both vulcanized to a rigid phenolic ring. This cartridge seat provides a stable platform, eliminating movement of the PTFE and elastomer.

-The Flow Line shaft seal is achieved through a continuous pressure exerted from the flatted area of the seat to the machined flatted area of the disc.

-These matching flatted surfaces provide a wide sealing area for the elastomer backed PTFE seat to exert pressure against, forming the primary seal.
