My company production of BQ641 pneumatic thermal insulation ball valve with good cooling characteristics, and pneumatic jacket insulation valve through the same diameter and diameter, and can effectively reduce the heat loss of the pipeline in the medium. Pneumatic insulation ball valve is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems, in order to transport at room temperature will be solidified high viscosity medium. As a result of the overall structure, so what kind of insulation ball valve than smaller, lighter weight, and no leakage, good sealing performance, the use of carbon steel welded jacket casting more pressure than solid.

Using a new type of pneumatic actuator, double action and single action (spring), gear rack drive, safe and reliable; AW series of large diameter valves using pneumatic actuator fork transmission, reasonable structure, large output force, double acting and single acting.
1, gear type double piston, the output torque is big, small volume.
2, cylinder selection of aluminum and gold material, light weight, beautiful appearance.
3. Manual operation mechanism can be installed on top and bottom.
4. Rack type connection can adjust opening angle and rated flow.
5, actuators optional live signal feedback instructions and accessories to achieve automatic operation.
6, IS05211 standard connection provides convenience for installation and replacement of products.
7, adjustable ends of the screw can make the standard product at 0 degrees and 90 degrees with the adjustable range of 4 degrees. Ensure the synchronization accuracy of the pneumatic ball valve with internal thread.

Six,Pneumatic insulation ball valveProduct selection

(1) valve parameters: nominal diameter, working pressure, process media, the use of occasions, valve material and other parameters.
(2) actuator parameters: actuator form, control mode, control signal (4-20mA, 1-5V), mode of action (gas open type, gas closed type)
As far as possible to provide detailed technical parameters of pneumatic insulation ball valve, convenient for our company sales and technical personnel for your accurate selection. If you have any questions, you can call us, we will do our best to provide you with high quality service!
