The cast steel globe valve has many advantages, and has been widely used for its high stability and good sealing. The new cast steel globe valve also adds some control partition function on its advantages.

Many times we can clearly grasp from the simple structure of the hard sealed butterfly valve, its performance and structural characteristics can be mastered, and it uses different series of rubber rings to fix the advantages of the installed valve body.

Combined with the stability of the cast steel gate valve, in between the turbine drive, the use of the release of the clamping state of some of the valve bodies, will be positioned and prevent drift phenomenon of chafing way, stainless steel butterfly valve use blind plate with the use of flexible operation, more self-locking and increase some features of the water cooling mechanism. The analysis of the characteristics of concentration can be flexibly mastered.

Different series of cast steel globe valve hard sealing methods, stainless steel butterfly valve installation body above the manual fixed base, after reasonable positioning, will avoid and seal abrasion. It can increase its high temperature resistance in the water-cooled state. The temperature reached and the dry dust removal mode is applicable for more use in the selected mode.

In the adoption of open and selective computer program control, structural and rigid requirements are also the expression of the permanent use of parts. The characteristics and synchronization of many cast steel globe valves are very good, and the use of stainless steel butterfly valves and spring tightening mechanisms makes use of many metallurgical alternatives.

The installation and maintenance of cast steel globe valve should pay attention to the following matters:

1. The handwheel and handle operated globe valve can be installed in any position of the pipeline.

2. Handwheel, handle and flexible mechanism are not allowed to be used for lifting.

3. The flow direction of the medium should be consistent with the arrow direction shown in the valve body.

The purpose of the cast steel globe valve The globe valve refers to the valve where the closing part (valve disc) moves along the center line of the seat. According to this form of movement of the valve disc, the change of the valve seat port is proportional to the stroke of the valve disc.

Because the stem opening or closing stroke of the cast steel stop valve is relatively short, and it has a very reliable cutting function, and because the change of the valve seat port is directly proportional to the stroke of the valve disc, it is very suitable for the adjustment of the flow rate. Therefore, this type of valve is ideal for use as a cut-off or regulation as well as throttling.

Once the disc of the cast steel globe valve is removed from the closed position, there is no longer contact between its seat and the disc sealing surface, so the mechanical wear of the sealing surface is very small, so its sealing performance is very good, the disadvantage is that the particles in the flowing medium may be caught between the sealing surface.

However, if the valve disc is made into a steel ball or a porcelain ball, this problem will be solved. Because the seat and disc of most globe valves are relatively easy to repair or replace, and the entire valve does not need to be removed from the line when the sealing element is repaired or replaced, this is very suitable for applications where the valve and the line are welded together.

Because of the change in the direction of the flow of the medium through such valves, the smaller flow resistance of the stop valve is also higher than that of most other types of valves.

However, this condition can be improved depending on the body structure and stem layout relative to the inlet and outlet channels. At the same time, because the travel between the opening and closing of the globe valve disc is small, the sealing surface can withstand multiple opening and closing, so it is very suitable for frequent switching occasions.

Cast steel globe valves can be used in most medium flow systems. Various forms of stop valves have been developed to meet the needs of petrochemical, electric power, metallurgy, urban construction, chemical and other departments.
