The principle of bellows globe valve

Bellows globe valve adopts the design of the bellows seal, completely eliminates the common valve gate valve stem packing seal aging fast easy leakage faults, not only improve the efficiency of the use of energy, increase production equipment safety, maintenance cost was decreased, and the frequent maintenance, also provides a clean and safe work environment. Use the advantages: double seal design ( Bellows + packing) If the corrugated pipe failure, the valve stem packing will avoid; External leakage, and conform to the international standard for sealing; No fluid loss, reduce energy losses, improve plant equipment safety; Durable bellows seal design, to ensure that the valve rod of zero leakage, provided no maintenance conditions; Long service life, reduce maintenance frequency, lower operating costs.
