Both valve types provide quarter-turn operation, but their cost, envelope, flow path and maintenance characteristics differ significantly as size increases.
Size and weight
Butterfly valves are generally lighter and shorter face-to-face at large diameters.
Flow characteristics
A full-bore ball valve offers an unobstructed path, while a butterfly disc remains in the flow.
Sealing duty
Pressure, temperature, media and leakage requirements determine the suitable seat and design.
Lifecycle review
Compare actuator size, installation loads, maintenance access, spares and total installed cost.
Information to include with an enquiry
Provide nominal size, pressure rating, medium, temperature, connection standard, materials, operating method, required testing and project documentation. Greysen will review the duty and confirm the final configuration in the approved data sheet.
