Stainless steel jacket insulated ball valve BQ41Y-16P

Stainless steel jacket insulated ball valve BQ41Y-16P

It has good insulation and cooling characteristics, and the valve diameter is consistent with the pipe diameter, while effectively reducing the heat loss of the medium in the pipeline.

Widely used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, and food to transport high viscosity media that solidify at room temperature.

Due to its integral structure, it is smaller in size, lighter in weight, and has no leakage, with good sealing performance. The jacket is welded with carbon steel pipes, which are more pressure resistant and firm than those cast.

Adopting an integral jacket structure design, it can provide more uniform insulation and cooling. The insulated ball valve has a smaller volume, lighter weight, and no leakage compared to general ball valves, with good sealing performance. The jacket is made of welded carbon steel pipes, which are more pressure resistant and firm than cast ones. The outer side of the jacket and valve body is welded to the jacket connecting pipe, allowing a maximum pressure of 1MPa for steam or cold water.

When the diameter and diameter of the valve are the same, the medium flows in a straight line with low resistance, which can effectively reduce the heat loss of the medium in the pipeline. Therefore, it has excellent performance for liquid media that are prone to solidification and high viscosity.

Due to its integral structure, it has a smaller volume, lighter weight, no leakage, and good sealing performance compared to general ball valves. The jacket is made of welded carbon steel pipes, which are more pressure resistant and firm than cast ones. Scope of application: Urban construction, chemical industry, metallurgy, petroleum, pharmaceuticals, food, beverage, environmental protection.

By setting up static steel balls, this jacketed insulated ball valve can eliminate static electricity on the valve core, prevent electric sparks, and increase usage time. Meanwhile, flexible graphite materials are used for gaskets, butterfly springs, pressure rings, and sealing rings, enhancing the sealing performance of insulated ball valves. Overall, this jacket insulated ball valve has a clever structure and good sealing performance.

The products are mostly insulated flange ball valves. One type is a split structure, where the valve body and valve cover are insulated separately. This type of insulated ball valve has problems such as large volume, complex structure, easy leakage, and poor insulation effect. Another method is to embed the valve cover with a reduced diameter in the structure, and its insulation jacket is welded separately. The actual nominal diameter is only 80%, which also has the defect of poor sealing performance.

At present, due to the limitations of valve sealing structure and corresponding sealing materials, the suitable temperature for some insulated ball valves is less than 200 degrees Celsius. If used for a long time at 200 degrees Celsius, the service life will be shorter.
