50V-Stack Seal Assembly for oil & gas
V-Stack seal assembly are used in various Oilfield Downhole equipment such as various Valves etc. Chevron seals are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
Due to its special design, the V-Stack seal assembly is very sensitive to the change of fluid pressure, so that it can deflect in the whole radial part, so as to increase the sealing load and effectiveness according to the proportion of applied pressure. In the assembly, the energized axial force is transmitted between each packing ring, so that each packing ring forms positive contact with the surface of the mating hardware. Special material grades are suitable for various working conditions.

The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions. The chevron seal stack material could be PEEK, modified PTFE and spring.
A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.
