API600伞齿轮闸阀
API600闸阀特点
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.没有产品污染的气密性。
No product contamination absolute tightness.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.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.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).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 replaced after removal of wedge from the body. Shut off flow and relieve pressure before replacing the seat insert.
