软阀座T形阀内件
SOFT SEATED “T” TRIM

　　所有阀门都可以配置备选的软阀座聚四氟乙烯(PTFE)阀内件。这种模铸聚四氟乙烯环粘合在阀瓣表面的槽内，最大限度延长使用寿命。这种结构对于要求紧密性关闭的低温应用特别适用。
　　All valves are available with optional soft seated PTFE trim. The molded PTFE ring is bonded into a groove in the disc face for maximum service life. This design is excellent for lower temperature service where tight shutoff is required.
