A bellow seal valve used bellow instead of stuffing box as valve stem sealing components to avoid the leakage of the valve stem. 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.
A bellow seal globe valve is operated as an obstruction between fluids and air. At the same time, the valve can prevent fluids leaking to the air and guarantee zero leakage of pipelines.
