BQ641F Pneumatic insulated ball valveDetailed product description：

ball valve Pneumatic insulated ball valve

BQ641F ball valve 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. Mainly 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, the insulated ball valve is smaller, lighter, leak free, and has good sealing performance compared to ordinary ball valves. The jacket is made of welded carbon steel pipe, which is more pressure resistant and firm than cast ones.

Ordering Instructions
