100Valve insert seal for frac pump
With the increase of China's oil consumption, oil production equipment is also increasing year by year. The consumption of vulnerable parts of fracturing truck, mud pump, cement truck and other equipment in major oil fields is huge. Therefore, major oil fields are looking for efficient products to ensure the long-term normal operation of these equipment. Formula polyurethane elastomer products - valve insert, which quickly entered this market.
The valve assembly is composed of valve disc, valve cover, valve seat, guide claw, nut, etc. the valve is sealed and buffered by the valve insert.
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.
Valve insert has the properties of damage and extrusion resistance. It has good compatibility with various fluids in industry, especially some harsh substances, such as H2S. Because of its ability to resist acid gas, it has become a high-quality sealing material in industry.

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's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be PEEK, modified PTFE.
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.
Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.
Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.
KZT is used in combination with anti-wear and piston ring to prevent cylinder oil from mixing with foreign particles, avoiding seal damage.
Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.
The FDR seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange external face seal.
