Advantages
\n\u2022
\n1, The bellows globe valve, its key component metal bellows, the lower end and the valve stem assembly using automatic roll welding, the upper end and the connecting plate automatic roll welding welding, forming a metal barrier between the fluid
\nmedium and the atmosphere, to ensure that the valve stem zero leakage.
\n2, The valve disc adopts parallel design, the sealing effect is better, the service life is long.<\/p>\n

3, Double durable bellows seal design (bellows + packing), to ensure zero leakage of the valve stem. No fluid loss, improve the safety of factory equipment. And meet the international sealing standards.
\n4, The valve cover comes with grease joint, which can directly lubricate the valve stem, nut and shaft sleeve, unlike the traditional lubricating thread only.
\n5,The valve stem tempering and surface nitriding treatment, has good anti-corrosion and anti-friction performance; Valve stem lifting position indication, more intuitive. Sealing surface surfacing Co based cemented carbide, wear resistance, corrosion
\nresistance, good anti-friction performance, long service life.<\/p>\n\n\n\n\n\n\n\n
