AP & DVC unveiled a bucket-type isolation valve ideal for hot fly ash, sewage sludge, cement, and dust without any insulation problems. Man-made interference is the hopper exports, the insulation valve frequently encountered a problem. Sliding gate valves are commonly used in insulating buckets, however, lacking the capability to be designed at the horizon. The problem occurs when the vehicle is built in and controlled by the area. The valve can not be fully closed to prevent effective insulation. AP & DVC designed bucket insulation valve, to avoid human interference in the operation. This realizes the potential problem of eliminating the establishment of the vehicle. Valves do not drop to the lowest point when in a closed position and control doors that are not in the media flow.



Angular contact ball bearing can withstand both radial load and axial load. Able to work at a high speed. With larger contact angle, the axial capacity of the bearing will be higher. High precision and high speed bearings usually have a 15 degree contact angle. The contact Angle will increase under axial force.

Angular contact ball bearing accuracy class includes dimensional tolerance and rotation precision.The precision is expressed as P0(ordinary), P6(P6X), P5, P4 and P2.In addition, the European and American brands also use P3, P7 and P9 to indicate the accuracy level. P3 is the P6 level of ISO and JIS standard, P7 is equivalent to P4, P9 is equivalent to P2.


Single row angular contact ball bearings application are:machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, filling machine, low noise type cooling tower, electrical equipment, coating equipment, machine tool trough plate, arc welding machine.
