 Cast Iron Flange Type Ball Valve


What is the Purpose of a Cast Iron Flange Type Ball Valve?

The Cast Iron Flange Type Ball Valve serves a critical function in fluid control systems. Its primary purpose is to start, stop, or regulate the flow of liquids, gases, or steam in pipelines with minimal leakage. The flange design ensures a tight and stable connection to piping networks, while the ball mechanism allows smooth operation and minimal resistance.

I often get asked: "Why should I consider a cast iron flange type ball valve over other types?"
I answer: "Because it offers excellent pressure handling, corrosion resistance, and a long service life, making it ideal for industrial applications such as water treatment, chemical plants, and HVAC systems."


Performance and Application

The Cast Iron Flange Type Ball Valve is highly valued for its operational efficiency and reliability. Here's a summary of its key performance parameters:

Parameter Specification
Material Cast Iron
Connection Type Flanged
Pressure Rating PN16/PN25 (customizable)
Temperature Range -10°C to 120°C
Operation Manual, Electric, or Pneumatic
