Forged steel globe valve is not only suitable for medium and low pressure, but also suitable for high pressure. It is widely used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other industries. It is used to cut off or connect regulating pipeline medium.
1. Compact structure, beautiful shape, reduced diameter channel. Structural features: B.B. or W.B;
2. The sealing surface is made of alloy steel or cemented carbide, the material of sealing pair is reasonable, and the service life is long;
3. The valve disc is conical, and the valve stem is equipped with reverse sealing, which has good sealing performance. The surface of valve rod is nitrided, which has good corrosion resistance and friction resistance. Flexible graphite packing, reliable sealing, flexible operation, small opening and closing torque;
4. Various piping standards and connection forms (such as socket welding, butt welding and threaded connection) can be selected.
