產品結構特點 Construction features

1、 超長壽命設計 

閥座、密封圈由金屬材料制成，且做表面硬化處理，就算啟閉頻繁，閥門仍能保持高的密封性能，杜絕了多層次密封結構不耐沖刷等弊端，極大提高了閥門的使用壽命；

2、依靠扭矩密封 

閥門至始至終都能保持的雙向密封性能，閥門密封不依靠介質力，由驅動裝置提供的扭矩實現密封，閥門在高、低壓下均能可靠密封。密封性能檢測結果符合API609、ISO5208等標準之規定；

3、閥座/密封圈可現場更換

可更換式閥座/密封圈設計，便于閥門現場維護保養；

4、填料密封的高性能

采用組合式填料密封系統，確保閥門泄漏率≤20ppm?？蛇x用動載密封結構，使填料持久密封，延長填料免維護周期；

1. Long life design

Seat, sealing completely made of metal materials, and surface hardening treatment, even if the opening and closing is frequent, can still maintain a high sealing performance of the valve, put an end to the multi-layer sealing structure not scour resistance and other shortcomings, greatly improve the service life of the valve;

2. Rely on torque seal

Valve throughout can keep superior two-way sealing performance and valve sealing force does not rely on media, completely provided by the drive torque seal, valve can reliable sealing under high and low pressure. The sealing performance test results are in accordance with the standards of API 609 and ISO5208.

3. The seat/sealing ring can be replaced on site

Replaceable seat/sealing ring design to facilitate valve site maintenance;

4. High performance of packing seal

The combined packing sealing system is adopted to ensure the maximum leakage rate of valve is less than 20ppm. The movable seal structure can be used to keep the stuffing durable and prolong the packing period.
