High-performance Sealing: Pure Graphite PTFE Packing

Pure Graphite PTFE Packing is a high-performance sealing material that combines the exceptional chemical resistance and low friction properties of PTFE (polytetrafluoroethylene) with the outstanding thermal conductivity and self-lubricating capabilities of pure expanded graphite. Engineered through an advanced composite manufacturing process, this material delivers superior sealing reliability for dynamic and static applications under extreme conditions, including high temperatures, aggressive chemicals, and high-pressure environments. It is widely used in pumps, valves, mixers, and reactors across industries such as chemical processing, pharmaceuticals, food and beverage, and power generation.

POM--High-performance engineering plastics

POM is a highly crystalline thermoplastic engineering plastic, which is favored for its high strength, high rigidity, wear resistance and low friction. It is widely used in machinery manufacturing, automobile industry, electronic appliances, medical equipment and other fields, and is known as the "metal in plastic".

About Hypalon rubber sheet

Chlorosulfonated polyethylene rubber sheet, also known as Hypalon rubber sheet. It's known for exceptional resistance to chemicals,weathering, and UV resistance. It has an excellent mechanical & good abrasion properties even without reinforcing filters and hasreasonable resilience in grades over 60°shore A. It displays good resistance to heat, ozone, oil and weathering and also gives good adhesion to metal. The recommended operating temperature range is between-40C to +125℃.

Nylon Sheet

Nylon, a synthetic polyamide engineering plastic, is widely used in various industries due to its excellent physical properties, wear resistance and chemical resistance, especially in the automotive, electronics, electrical, textile and industrial manufacturing fields. Since it was first developed by DuPont in the 1930s, Nylon has become one of the most important plastics in the world. Its characteristics include high strength, good elasticity, heat resistance, and strong chemical resistance, making it an indispensable basic material in modern technology and daily necessities.

Mica Sheet

Mica sheet like insulating material made from natural or synthetic mica, combined with a high performance adhesive and processed through a series of processes, including high-temperature and high-pressure processing, baking, and lamination. It perfectly combines the excellent properties of natural mica with the ease of forming modern industrial materials, making it an indispensable and critical insulating material in industries such as electricity, electronics, and metallurgy.

What are the differences between resilient soft-seated gate valves and hard-seat

Hard sealing is a metal-to-metal seal, where both the sealing ball and valve seat are made of metal. The processing accuracy and technology are more difficult, and it is generally used in high-pressure applications, usually above 35 MPa. Soft sealing is a metal-to-non-metal seal, such as nylon or PTFE, and the manufacturing standards are the same.
