High pressure casting cut-off valve has four advantages

Author:admin Popularity: Issuing time:2018-07-19 17:47

The change in the seat passage of the high pressure casting stop valve is proportional to the valve stroke. The valve stem opening or closing stroke of the high pressure shut-off valve is relatively short and has a very reliable shut-off function. Since the change of the seat passage is proportional to the stroke of the valve flap, it is very suitable for adjusting the flow rate. This type of shut-off valve type is therefore very suitable for use as a cut-off or adjustment and throttling.
The stroke between the valve opening and closing of the casting stop valve is small, and the sealing surface can withstand multiple opening and closing. Therefore, the shut-off valve is suitable for occasions requiring frequent switching and can be used in most media flow systems. The globe valve is widely used in petrochemical, electric power, metallurgy, urban construction, chemical and other industries.



Structural characteristics of high pressure casting stop valve
1. The valve stem is heat treated and has good scratch resistance and wear resistance.
2, a variety of connection types can be used to meet various piping requirements and piping flange standards and flange sealing surface forms to meet various engineering needs and user requirements.
3. The sealing surface of the valve disc and the valve seat is sprayed and welded with different hardness of cemented carbide. Reliable sealing, high hardness; wear resistance, high temperature resistance, good scratch resistance and long service life.
4. The national standard flange connection, socket welding connection, butt welding connection and thread connection stop valve series are the conventional products designed with reference to the national standard. The cast steel globe valve series has reasonable structural design, stable performance, reliable quality, convenient installation and light operation. Flexible and so on.
