Product Description

Electric bellows regulating valve Overview:
The electric bellows seal regulating valve uses bellows as the valve stem sealing element, which can make the valve stem part without leakage to prevent radioactive substances or valuable substances from leaking out, or maintain a high vacuum. It is often used in occasions where the valve stem seal is strictly required, such as for high vacuum occasions and in the nuclear industry.

Electric bellows regulating valve features:
The valve cover of the electric bellows regulating valve adopts the corrugated pipe seal structure, which can completely eliminate the possibility of process media leaking outward from the movement gap of the valve stem, which is one of the remarkable characteristics of the bellows sealing valve. Due to the deformability of the bellows component itself and its outstanding anti-aging property, this regulating valve completely overcomes the packing seal valve, which usually has weaknesses such as packing aging and temperature difference sensitivity. Secondly, the use of bellows a packing double seal structure, safety and reliability is better, therefore, it is highly toxic, strong corrosion, radioactivity and other rare special media, automatic control system has been widely used.
