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.
V Packing consist of multiple male and female adaptor, usually a group of three to seven v rings, used for low or high pressure applications with Single or Double acting cylinder.
Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. It has high mechanical properties, good oil resistance, low water absorption and high wear resistance.
SPGW is a high performance, double acting compact piston seal, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
JST's ESU series stem packings, also known as u packing, are designed to be placed between the stem and bonnet of Type FC gate valves. This stem packing gives you a reliable seal for superior performance.
