Pneumatic stainless steel insulation ball valve, pneumatic insulation jacket ball valve, steam heat conduction oil insulation ball valve BQ641F

 

BQ641F pneumatic insulation ball valveThe piston is a pneumatic actuator and jacket insulation ball valve, has a good insulation and cooling characteristics, and pneumatic insulation ball valve diameter and diameter consistent, but also can effectively reduce the medium heat loss in the pipeline. Valve positioner can be input control signal (4-20mADC or 1-5VDC) air source can control the operation. The switch can be operated with the limit switch, solenoid valve, triple component and 0.4-0.7MPa gas source, and two pairs of passive contact signal indicating valve switch can be sent out. Jacket insulation pneumatic ball valve is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems, to transport high viscosity medium at room temperature. Because the pneumatic insulation ball valve adopts the integral structure, the jacket insulation pneumatic ball valve has smaller volume, lighter weight and no leakage than the general ball valve, and the sealing performance is good, and the jacket is welded by carbon steel pipe, which is more stable than the casting.
