You should know that in the valve tool market with such fierce competition and so many varieties, coupled with the continuous development of the inlet and outlet pneumatic ball valve business, the market development prospect and superior market environment of pneumatic ball valve products can be explained naturally.

The rotary compensator is a new type of compensator for thermal pipe thermal contraction compensation. The structure of rotary compensator is mainly composed of integral seal seat, seal gland, reducer, antifriction centering bearing, seal data, rotating cylinder and other components. The device needs more than two pairs on the thermal pipeline to form a relative rotating absorption pipeline thermal displacement, so as to reduce the stress of the pipeline.
Advantages of rotary compensator:
(1) The compensation amount is large, which can be arranged according to the natural terrain and pipeline strength. The largest group of compensators can compensate 500m pipe section;
(2) . There is no blind plate force generated by medium pressure, and the fixed support can be made very small, especially suitable for large diameter pipes;
(3) Excellent sealing performance, long-term operation without maintenance;
(4) Investment is greatly saved;
(5) Convenient design and calculation;
(6) The rotary compensator can be installed on the buried steam pipe and the buried hot water pipe, which can greatly save investment and improve the safety of operation.
The rotary compensator is usually installed on the pipeline for 150~500m
