The soft seated ball valves provide variety advantages and excellent performance such as superior shut-off across a range of pressure with minimum operating torque, cryogenic operation for service down to -196°C, fugitive emission ISO15848, oil free, corrosion resistance and so on. This Qublock soft seat ball valve has been specially designed for rugged oil field and petrochemical applications – Polymerization (PE/PP), EDC/VCM/PVC, Steam cracking, Polysilicon, Propane dehydrogenation and also ultra pure application - semiconductor, display, DI water.
A choice of body, trim, and seat materials is available to suit an extensive range of applications. Qublock soft seated ball valves meet the special requirement of its customers with valves that are designed on the basis of accurate data, extensive experience, excellent technical know-how, and superior precision marching.
The double seal structure is designed according to ISO 15848. All parts where emission is possible have two stages of sealing structure with soft seals.
Soft-seated Qublock ball valves exhibit a tight shut-off sealing performance. This is the result of trustable engineering data and excellent production control.
Depending on customer requirements, the best suitable materials is selected from among various materials.
The combination of ball and seat is the most critical part of a valve; thus, Qublock provides Hard-Facing solutions on the basis of past experience, operation cycle, and compatibility with the base material as well as fluid conditions.
