Rubber V Packing hydraulic seals

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.

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.

The function of a hydraulic wear ring is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.

EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals.

The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a stem seal.

SPGO is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, 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 ESY series design is commonly used as dynamic seal for ball valve stem, and the ESY with various V rings and T shape support rings could be used for fugitive emission valves, meeting the requirements of ISO-15848.

The ball valve seat is responsible for sealing the fluid inside and uniformly distributing the seating stress. A leak of ball valve in petrochemical application could be environmentally devastating.
