Steam Ball Valves: Features & Technical Parameters

Steam ball valves refer to ball valves applied in steam pipelines. They are mainly used for cutting off, distributing and changing the flow direction of steam in steam piping systems. Steam ball valves are primarily suitable for various high-pressure medium transmission pipelines in industries such as chemical engineering, metallurgy, petroleum and pharmaceuticals.

Features of Steam Ball Valves

1. Premium Valve Body Material: The valve body of the steam ball valve is made of imported high-quality steel, featuring high temperature resistance, high pressure resistance, low temperature resistance and wear resistance.

2. Dual Sealing Material Options: There are two main types of sealing materials for steam ball valves. First, soft sealing uses high-quality polytetrafluoroethylene (PTFE) or high-quality PPL, which not only achieves excellent sealing performance but also can be used in certain high-temperature environments. Second, metal hard sealing adopts high-quality metals or alloys with precision processing, delivering wear resistance, pressure resistance and temperature resistance.

3. Special Lubricated Sealing Surfaces: The sealing surfaces of the steam ball valve undergo special lubrication treatment, resulting in minimal friction with the ball and an extended service life.
