Description & Features

Primarily designed to meet the stringent requirements and safety levels of the oil & gas industry, this high performance butterfly valve is available in a range of sizes, from 2 inches to 80 inches (DN 50-2000). This makes them ideally suited for a host of applications, including firewater, hydrocarbons, cargo handling, bilge and ballasts and utilities, just to name a few.

● Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life.

● Unique packing design allows for use in pressure as well as vacuum without modification or special assembly.

● Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts reducing packing leaks.

● Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life.

● Blow-out resistant shaft is standard on all valves for increased safety.
