阀瓣类型
Disc Types

　　美国太平洋截止阀可提供各种类型的阀瓣，以满足特定关闭和节流应用的要求。参阅适用于节流应用的应用建议(第32页)
　　Pacific globe valves are available with a choice of disc types to meet specific shutoff and throttling applications. See service recommendations (page 32) for throttling applications.

塞型阀瓣
Plug Disc

　　目前能够提供的最简单，最经济的阀瓣类型。所有通径阀门的这种阀瓣是通过阀杆引导的。这类阀瓣具有不同的角度面对阀座，因此具有线接触作用，从而实现最大限度的密封。适用于现场维修的最简单的阀瓣类型。
　　Simplest and most economical disc type available. The disc is stem guided on all sizes. Disc has a differential angle front the seat to provide a line contact for maximum sealing. Simplest disc type for field repair.

V形端口阀瓣
V-Port Disc

　　备选阀瓣结构，适用于要求更好的线性节流特性的应用场合。阀瓣底部由阀体阀座环引导，最大限度提高阀瓣在节流应用中的稳定性。V形端口阀内件的阀门配置不旋转阀杆，在轭架上安装位置指示器。特别适用于应用环境不太严酷，但是要求具有近似线性特性的场合。
　　Optional disc configuration, where more linear throttling characteristics are required. The bottom of the disc is guided by the body seat ring for maximum disc stability in throttling applications. Valves with V-port trim are provided with non-revolving stems and position indicator assemblies on the yoke. Ideal for non-severe throttling service where near linear characteristics are required.

球型阀瓣
Ball Type Disc

　　备选阀瓣结构，在球形阀瓣和锥体阀座之间具有线接触作用。这种结构将未硬化不锈钢阀座的磨损可能性降到最小程度，也降低了卡在阀体阀座上的可能性。
　　Optional disc configuration which provides line contact between spherical disc and conical body seat. This design minimizes galling tendency with non-hardened stainless steel seats and is less likely to stick in the body seat.

备选软阀座阀内件
Optional Soft Seated Trim

　　所有截止阀都可配置备选特氟隆阀瓣。这种模铸特氟隆环粘合在阀瓣的槽内，最大限度延长使用寿命。这种结构对于较低温度，并且要求紧密关闭的应用环境非常理想。指定T阀内件(参阅第33页)
　　All globe valves are available with optional Teflon disc. The molded teflon ring is bonded into a groove in the disc for maximum service life. This design is excellent for lower temperature service where tight shutoff is required. Specify “T” trim (see page 33).

标准阀盖连接
Standard Bonnet Joints

　　美国太平洋阀门上的阀体/阀盖连接结构适用于恶劣的应用环境，可配置足够数量的阀盖螺栓。
　　这些标准的连接随着阀门压力等级的不同而有所不同。这些标准连接如下所示。
　　Body/bonnet joints on Pacific valves are designed for rugged services with a more than adequate number of bonnet bolts.
　　The standard joint varies, depending on valve class. These standard joints are shown.
