Product Description: NIKO Niko electric bellows control valve uses a bellows as the valve stem sealing element, ensuring no leakage at the valve stem to prevent the escape of radioactive or valuable substances, or to maintain high vacuum. It is commonly used in applications with strict requirements for valve stem sealing, such as high vacuum environments and the nuclear industry.
NIKO Niko Electric Bellows Control Valve Structural Features: The upper valve cover of the electric bellows control valve adopts a bellows sealing structure, completely eliminating the possibility of process medium leakage from the valve stem movement gap. This is one of the notable features of bellows-sealed valves. Due to the bellows element's excellent deformability and aging resistance, this control valve overcomes the common weaknesses of packing-sealed valves, such as packing aging and sensitivity to temperature differences. Additionally, the double-sealing structure of bellows and packing ensures better safety and reliability. Therefore, it is widely used in automatic control systems handling highly toxic, highly corrosive, radioactive, and other rare special media.
