Ball Valves

Gelişim Ball Valves, conforming the API 6D standards, have two part bodies and are full transitive and narrow transitive.  They provide laminar flow and the pressure loss is low.

Ball valves have soft seat, normal and fire-safe types.  They are used either to fully permit or prevent flow, or in some cases, to regulate flow.  Depending on the distance between flanges, it is produced in different constructive properties, called long and short types.

Ball valves, with the actuator on it, have the 90 degree practical opening-closing feature.  With increasing valve dimensions, different actuators gain importance.  In Class 150 pressure group, 8” and larger, in Class 300 and Class 600 groups, 6” and larger valves, it is better to control them with actuators with gearbox, for the ease of opening and closing.

  • Body

    It is produced in two different transition diameters, for full and narrow transition. Ring seating socket is sensitively processed.  The body is designed to prevent all kinds of flow irregularity.  Teflon rings sit on the seating surfaces of the body in a safe and leak-proof way. 

  • Ball

    Cast stainless steel (A351 CF8 or A351 CF8M) used in GELİŞİM ball valves is casted in the best conditions.  In ball form, polishing is applied after machining.  For this reason, it is compatible with the Teflon rings, and leak-proof.
