タイトルまたは説明

KXC bellow seal valve has a compact structure and is one kind of control valve to balance the pressure. Bellows are used as the valve stem sealing components of the bellow seal valves.
To avoid the leakage of the valve stem, the valve adopts the structure with bellows instead of stuffing boxes generally used for the ordinary valve or the structure with both bellows and stuffing boxes. 
The bellow seal valve is particularly suitable for pipelines of steam and flammable, explosive and hazardous media. Moreover, because of bellow's properties of deformation and aging resistance, the bellow seal valve overcomes the common latent defects, including temperature sensitivity and the aging of the stuffing box, and these defects are owned by the valve sealed by packing.
