Technical guide

Valve selection begins with the duty.

Isolation, throttling or non-return service determines the valve family. Size, class, ends, body materials, trim, seat and operating method then refine the selection.

Flowline’s catalogue presents ball valves, wafer check valves, butterfly valves and knife-edge valves with drawings, materials and dimensional data. The online page converts that brochure-style information into a clearer technical buying sequence.

Before commercial confirmation, provide service medium, design pressure and temperature, valve type, nominal size, pressure class, end connection, body and trim expectations, operation method and quantity. This helps avoid selecting only by nominal size.

Within Industrial Valves

Different valve duties need different constructions.

Ball, check, butterfly and knife-edge valves are not interchangeable choices. Use the service and operating requirement to identify the right family first.
