BOP inner and outer seal

Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).

The valve stem packing is an essential component of valves, which is covered around the valve stem. The purpose of valve packing is to prevent leakage.

High pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure.

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.

The pump plunger sealing system is adopted in the pump, which can effectively prevent the damage caused by water leakage and prevent the pump failure caused by the plunger friction overheating.    

The JST valve insert seal is mainly used for sealing valve seat of fracturing pump. It is made of modified polyurethane material of excellent extrusion resistance, puncture resistance and fatigue resistance, which guarantees the fracturing work under various working conditions.

DKBI wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.

DLI is a dust resistance and oil-scraping double acting seal. Consist of PU and iron material.
