Technical Specifications
Key Features & Applications
A Triple Offset Butterfly Valve Supplier In Africa supplies valves designed for severe-service applications where high temperature, pressure and tight shut-off are important. African Valve provides triple offset butterfly valves for refinery, petrochemical, LNG, power generation, offshore and chemical-processing projects across Africa.
Unlike resilient-seated butterfly valves, the triple offset design uses three geometric offsets. These offsets allow the disc to move away from the seat during opening, reducing friction and wear. When closed, the disc engages with the metal seat to provide reliable shut-off for demanding process conditions.
