Q61N-320P Q61N-160P Сварной шаровой кран высокого давления из нержавеющей стали
Primarily used in long-distance oil and natural gas pipeline transportation and city gas pipeline systems. Due to the unique characteristics of valves for long-distance pipelines, their design fully considers their ability to withstand pipeline stress, as well as safety, weather resistance, and long-term reliability.
Suitable for Class 150～2500Lb, operating temperature 80～550℃ long-distance pipelines and general industrial pipelines. Its safety and resistance to harsh environments have been specially considered in the design. It is suitable for media such as water, масло, пар, газ, and natural gas.

Q61N-320P Q61N-160P Stainless Steel High-Pressure Welded 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. Однако, 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.
