產品結構特點 Construction features

1.雙重的密封設計（波紋管+填料）若波紋管失效，閥桿填料也會避免。
2.結構合理、密封可靠、性能優(yōu)良、造型美觀。
3.沒有流體損失，降低能源損失，提高工廠設備安全。
4.密封面堆焊Co基硬質合金、耐磨、耐腐、抗摩擦性能好、使用壽命長，減少維修次數，降低經營成本。
5.堅固耐用的波紋管密封設計，保證閥桿的零泄漏，提供無需維護的條件。
6.截止閥閥桿調質及表面氮化處理，有良好的抗腐和抗摩擦性能；
7.閥桿升降位置指示更直觀。
1. Double seal design (bellows + filler) if bellows fail, stem packing will be avoided.
2. Reasonable structure, reliable sealing, excellent performance and beautiful appearance.
3. There is no fluid loss, reduce energy loss, and improve the safety of plant equipment.
4. The cover surfacing the Co base carbide, wear-resisting, anti-corrosion, anti-friction performance, the service life long, reduce the maintenance times, reduce the operating cost.
5. Strong and durable bellows seal design to ensure zero leakage of stem and provide conditions without maintenance.
6. The cut-off valve stem and surface nitride treatment have good anti-corrosion and anti-friction properties;
7. Valve stem elevation position indication is more intuitive.
