Application and Classification Characteristics Cf Stainless Steel Globe Valves

Application and classification characteristics of stainless steel globe valves Stainless steel globe valves are popular due to their low friction between the sealing surfaces during opening and closing, durability, and lack of opening height. Large and easy to create. Easy to maintain, suitable for high and medium low voltage applications.

In various corrosive medium pipelines, stainless steel globe valves have excellent corrosion resistance and sufficient strength. In addition, alloy steel globe valves are suitable for high-temperature steam and oil pipelines, with high temperature resistance performance, and are widely used in industries such as petrochemical, chemical, power, metallurgy, medical, and food.

Advantages of stainless steel flange globe valves
1. Simple structure, more convenient for creation and maintenance.

2. Short working hours and short opening and closing times.

3. Good sealing performance, low friction on the sealing surface, and long service life.

4. The cut-off valve body structure includes straight through type, direct flow type, and right angle type. The straight through type is the most common structure, but its fluid resistance *. DC fluid has low resistance and is mainly used for solid particles or high viscosity fluids. The right angle valve body is mostly forged, suitable for globe valves with narrow channels and high pressure.

5. During the opening and closing process, the friction force of the sealing surface is less than that of the gate valve, making it wear-resistant.

6. Usually only one sealing surface is required, creating excellent craftsmanship and convenient maintenance.
Common Classification Of Stainless Steel Globe Valves
1. Stainless steel straight through globe valve

2. Stainless steel angle globe valve; In angle globe valves, the fluid only needs to change direction once, so the pressure drop rate is small, which is used for traditional structure globe valves that pass through the valve.

3. Stainless steel straight through globe valve; In straight through or Y-shaped globe valves, the flow path of the valve body is diagonal to the main flow path, so the degree of damage under flow conditions is as follows. Due to being a traditional globe valve, the pressure loss through the valve is relatively small.

4. Stainless steel plunger type globe valve: This globe valve is a variant of traditional globe valves. In this type of valve, the disc and seat are usually designed based on the plunger principle. The valve cracks are polished to connect the plunger to the valve stem, and two elastic sealing rings with sleeves on the plunger provide sealing. The two elastic sealing rings are separated by sleeve rings, and the sealing ring near the plunger is compressed by the load applied by the valve cover nut on the valve cover. The elastic sealing ring is replaceable and can be made of various materials. This valve is mainly used for "opening" or "closing", but is equipped with a special shaped plunger or special collar to regulate flow.
