产品结构特点 Construction features

1.双重的密封设计（波纹管+填料）若波纹管失效，阀杆填料也会避免。
2.结构合理、密封可靠、性能优良、造型美观。
3.没有流体损失，降低能源损失，提高工厂设备安全。
4.密封面堆焊Co基硬质合金、耐磨、耐腐、抗摩擦性能好、使用寿命长，减少维修次数，降低经营成本。
5.坚固耐用的波纹管密封设计，保证阀杆的零泄漏，提供无需维护的条件。 
6.截止阀阀杆调质及表面氮化处理，有良好的抗腐和抗摩擦性能；
7.阀杆升降位置指示更直观。
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.
