Product Description

Electric bellows seal regulating valve using bellows as stem sealing element, can make the stem position without leakage, in order to prevent radioactive material or valuable material leakage, or maintain a high vacuum. It is often used in the occasions where the valve stem seal is strictly required, such as the occasions of high vacuum and the nuclear industry.



Electric bellows regulating valve features
The valve cover on the electric bellows regulating valve adopts the corrugated tube seal structure, which can completely eliminate the possibility of process media leaking outwards from the movement clearance of the valve stem, which is one of the remarkable characteristics of the bellows sealing valve. Due to the deformation and outstanding aging resistance of the bellows element itself, the regulator completely overcomes the packing seal valve, usually existing packing aging and sensitive to temperature differences and other weaknesses. Secondly, the bellows a packing double sealing structure, better safety and reliability, therefore, it is highly toxic, strong corrosion, radioactivity and other rare special media, automatic control system has been widely used.
