High-Pressure Ball Valves: Product Description, Features & Selection Parameters

1. Product Description

High-pressure ball valves are mainly used in long-distance oil and natural gas pipeline transportation and urban gas pipeline systems. Due to the unique characteristics of valves for long-distance pipelines, their design fully considers the ability to withstand pipeline stress, as well as safety, weather resistance, long-term reliability, and sealing structure design.

They are suitable for long-distance transmission pipelines and general industrial pipelines with Class 150～2500Lb and operating temperature of 80～550℃. Special considerations have been given to their safety and harsh environment resistance design, making them applicable to media such as water, oil products, steam, gas, and natural gas.

2. Product Features

1. All components of this product are forgings.

2. Adopts a bottom-loaded stem with a backseat seal structure.

3. Uses an inlaid valve seat with an O-ring installed behind the seat to ensure no medium leakage.

4. The sealing surface is made of nylon 1010, whose friction coefficient is usually 1/3 that of Babbitt metal, making it a naturally lubricious material. It has bending strength, impact strength, and high ductility comparable to those of metals.

5. The sealing surface can also be made of STL alloy for wear resistance and high-temperature resistance.

6. Equipped with anti-static and fire-safe design.
