Bellows sealed small-caliber single-seat control valve product introduction
Bellows sealed small-caliber single-seat control valve, the valve cover with corrugated structure, which can completely eliminate the process medium leakage from the valve stem clearance of the possibility of bellows seal valve which is one of the salient features of the valve Corrugated pipe element itself deformation and outstanding anti-aging, this electric single-seat control valve completely overcome the packing seal valve usually exists in the aging of the filler and temperature sensitivity and other weaknesses. Second, the use of a double bellows corrugated packing structure, better safety and reliability. Therefore, it is widely used in the automatic control system of rare special media such as highly toxic, corrosive, radioactive and so on. Electric control valve equipped with multi-spring film actuator, its compact structure, the output power.
