Q11N-160P, 320P Internal Thread High-Pressure Ball Valve product description
Q11N-160P/320P internal thread high-pressure ball valve is mainly used in long-distance pipeline transportation systems for oil and natural gas. 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, ETC. 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, 油, 蒸汽, 气体, natural gas and other media.
Q11N-160P, 320P Internal Thread High-Pressure Ball Valve 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. 然而, 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.
