Diyak Ltd. manufactures multiple-lip (chevron) Seals or Vee Packings that consist of a group of endless rings and are usually used for sealing rods, pistons, plungers in hydraulic cylinders and hydraulic presses. V-Packings are used for low or high pressure applications with Single or Double acting cylinder.
V-Packings are also used in various Oilfield Downhole equipment such as various Valves etc. V-Packings 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.
The hinge-line action of Vee-Packings that enables immediate reaction even to minor pressure changes is very distinctive and exclusive to a Vee-Packing design. Each individual lip of a Vee-Packing set reacts independently to pressure thus effecting aseal automatically. In case of multiple lip configurations, pressure is automatically distributed thus effecting a seal along the shaft. Vee-Packings also premit automatic reaction to shocks from high pressure and overloads.
The Vee-Packing is a combination of Base Seal, the Vee-Ring at the center and the Pressure ring. The Vee-Ring is the main seal that can retain high and low pressures while the base seal supports the center ring from getting extruded during high pressure applications. The Pressure Ring helps in retaining the Vee Packing profile and distributing pressure equally.
We stock a wide range of Vee Packing along with their Male and Female Adapters to suit various customer requirements.
Some of the standard materials in which Vee Packings are available are:
Graphite, Moly, Glass filled PTFE V-Packing
Filled PTFE (Filled with Glass, Graphite, Carbon, Moly etc) V-Packing
Homogeneous NBR 90 Shore A V-Packing
NBR Vee-Packings with Fabric reinforcement V-Packing.
Viton V-Packing.
Aflas V-Packing.
The right material for the Vee Packings is selected based on various factors some of which are:
Operating Pressure
Operating Temperature
Tpe of Gases or Fluids within operating medium etc.
Normally Fabric Vee Packings are used for High Pressure applications while Homogeneous Vee Packings are used for Low Pressure applications.
Installation:
A properly installed Vee Packing set will usually provide better results compared to other lip-type seals. Each Set contains a nmber of Vee-Rings based upon the pressure plus male and female adapters.
The Vee-Rings in each set are referred to as Pressure Rings.
Properly installed Vee Packings will generally outperform other lip-type seals. They are always installed in sets. Each set contains a number of V-Rings (based upon the pressure) plus male and female adapters. The V-Rings in each set are referred to as pressure rings.
We manufacture Vee-Packings in standard sizes and also as per your specific requirements.
