Forged steel globe valve is a “push switch” used on pipelines, which can be closed by pressing down and opened by lifting up. This valve is resistant to hammer and pressure, tightly sealed, and has a smooth opening and closing, specializing in the “violent cut-off” of high-pressure and high-temperature fluids.
The basic structural combination includes forged steel valve body, valve disc, valve stem, and handwheel. Below, we will reveal the functions of each part.
1. Forged steel valve body
Whole piece steel forging → no bubbles inside, able to withstand high pressure of 80MPa without bursting (three times that of cast iron valves!). Forging can make the molecules denser, and a hammer will not dent them. High pressure pipes are essential for refineries.
2. Valve disc
The conical “small plug” is vertically pressed against the valve seat, and after being tightened, it does not leak water. Sealed hard core, welded tungsten steel alloy (like diamond coating), resistant to particle erosion.
3. Valve stem
Coarse thread design, one turn up/down 2mm, precise control of opening and closing; Fill the stuffing box with graphite rings to prevent steam leakage at 500 ℃.
4. Handwheel
Equipped with labor-saving gears, it can easily compress high-pressure pipelines.Forged steel globe valves, with their excellent performance and structural characteristics, can be used for steam blocking in power plants and acid blocking in chemical plants!
