API600伞齿轮闸阀

API600闸阀特点

1. 通过阀座气密性的短程或远程保护提供完全关闭。
   Positive shutoff with visual or remote proof of seat tightness.
2. 没有产品污染的**气密性。
   No product contamination absolute tightness.
3. 双阀座：合成橡胶 -金属阀座加上金属-金属第二重密封。
   Dual seating.
   Elastomer-to-metal seat plus metal-to-metal secondary seal.
4. 防火：如果第二重合成橡胶阀座在火灾期间被损坏，则金属-金属阀座还可以保证气密性。
   Fire Safe.
   The metal-to-metal seat ensures tightness if the secondary elastomer seat is damaged during the fire.
5. PTFE阀座镶嵌件：抗介质的腐蚀，在工作温度达到204°C时，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不锈钢和密封焊接的阀座硬面。
   Seat hardfaced with SS 410 and seal welded.

易于在线进行阀门阀座维修
EASY IN-LINE VALVE RESEATING

阀座用410不锈钢进行硬面，通过焊接装配延长使用寿命。将楔板从阀体上拆卸后，磨损的软阀座镶嵌件就很容易更换了。在更换阀座镶嵌件之前，关闭流体，减轻压力。
Seats are hardfaced with SS 410 and welded-in for lifetime service. A worn soft seat ｉｎｓｅｒｔ can easily be r e p l a c ed after removal of wedge from the body. Shut off flow and relieve pressure before replacing the seat ｉｎｓｅｒｔ.
