API600傘齒輪閘閥

API600閘閥特點

1. 通過閥座氣密性的短程或遠程保護提供完全關閉。
   Positive shutoff with visual or remote proof of seat tightness.
2. 沒有產品污染的絕對氣密性。
   No product contamination absolute tightness.
3. 雙閥座：合成橡膠 -金屬閥座加上金屬-金屬第二重密封。
   Dual seating.
   Elastomer-to-metal seat plus metal-to-metal secondary seal.
4. 防火：如果第二重合成橡膠閥座在火災期間被損壞，則金屬-金屬閥座還可以保證氣密性。
   Fire Safe.
   The metal-to-metal seat ensures tightness if the secondary elastomer seat is damaged during the fire.
5. PTFE閥座鑲嵌件：抗介質的腐蝕，在工作溫度達到204°C時，具有很好的抗磨能力。
   PTFE seat insert
   resists corrosive media, has high abrasion resistance and operates
   up to +400°F (204°C).
6. 配置410不銹鋼和密封焊接的閥座硬面。
   Seat hardfaced with SS 410 and seal welded.

易于在線進行閥門閥座維修
EASY IN-LINE VALVE RESEATING

閥座用410不銹鋼進行硬面，通過焊接裝配延長使用壽命。將楔板從閥體上拆卸后，磨損的軟閥座鑲嵌件就很容易更換了。在更換閥座鑲嵌件之前，關閉流體，減輕壓力。
Seats are hardfaced with SS 410 and welded-in for lifetime service. A worn soft seat insert can easily be replaced after removal of wedge from the body. Shut off flow and relieve pressure before replacing the seat insert.
