US API High-pressure ball valve Q41N/Q61N/Q11N product description
High-pressure ball valves are mainly used for long-distance pipeline transportation of oil and natural gas and city gas pipeline systems. Due to the unique characteristics of the valve for long-distance pipelines, its ability to withstand pipeline stress, as well as safety, weather resistance, long-term reliability, و غیره. are fully considered during design. The sealing and structural design are unique to Kelico Company. It is suitable for long-distance pipelines and general industrial pipelines with Class 150~2500Lb and operating temperature of 80~550℃. Special considerations have been taken in its design of safety and harsh environment resistance. It is suitable for water, روغن, بخار, گاز, natural gas and other media.
US API High-pressure ball valve Q41N/Q61N/Q11N Product features
1. All parts of this product are forgings
2. Adopt bottom-mounted valve stem and equipment inverted sealing structure
3. Adopt an inlaid valve seat, and an O-ring is installed behind the valve seat to ensure that the medium does not leak.
4. The sealing surface is made of nylon 1010. Its friction coefficient is usually 1/3 of that of Babbitt alloy, so it is a naturally slippery material. با این حال, its bending strength, impact strength and high ductility are comparable to those of metal.
5. The sealing surface is made of STL alloy, which is wear-resistant and high-temperature resistant.
6 Anti-static and fire-proof design.
