截止止回阀
GLOBE STOP CHECK VALVE
消除侧面推力的阀体引导阀瓣
Body Guided Disc Eliminates Side Thrust
锻造阀瓣具有整体钨铬钴合金硬化阀座和导轨表面。它引导过程包括从头到尾的全过程。这就保证了阀座与阀瓣的完美对齐，不会受到流速太高和压差太大造成的侧面推力的影响。避免了阀杆粘着，刮伤和磨损，延长阀瓣、阀座和阀体的使用寿命。
The forged disc has an integral Stellite hardfaced
seat and guide surface. It is guided at the top and bottom. This assures
perfect seat and disc alignment is spite of the side thrust caused by
high flow velocities and pressure differentials. This protects the stem
from bending, scoring and galling and provides longer disc, seat and body
life.
整体钨铬钴合金阀座
Integral Stellite Seat
整体钨铬钴合金硬面阀座在抵抗高流速和由于极端温度改变和管道负载造成的变形所产生的侵蚀和磨损方面，具有最好的性能。
The integral Stellite hardfaced seat provides
maximum resistance to erosion and wear under high flow velocities and
distortion due to extreme temperature changes and piping loads.
截止止回阀
Stop Check Valve
备有适用于蒸汽应用的均压管道，或适用于很低流速应用的均压管道和活塞环。
Available with equalizer pipe for steam service
or with equalizer pipe and piston rings for very low flow applications.
低摩擦行程
Low Friction Stroking
- 头尾引导的阀瓣保证阀杆工作不会受到高压力流体产生的侧面推力的影响。
Top and bottom-guided disc assures stem operation
without side thrust caused by high pressure flow.
- 阀杆是不旋转的，这样就减少了所有运动部件的磨损，延长了阀杆填料的使用寿命。
Stem is non-rotating, resulting in lower friction
of all moving parts and longer stem packing life.
- 冲击式手轮的关闭力比普通手轮大3到10倍。这样就能够在极端压力下顺利、轻松的操作，紧密关闭阀门。
Impactor handwheel gives 3-10 times more closing
force than a standard handwheel. All this resulting in smooth, easy
operation and tight shutoff under extreme pressures.
易于在线维修
Easy Repairs In-Line
这个阀座都是可见的，因此在拆卸阀帽总装件后，能够迅速地进行在线维修。轻微的阀座磨损可以通过拆卸层叠进行修补，严重的磨损可以采用轻便的钻孔工具进行修补。压力密封区域也可以采用简单的镗磨工具进行表面整修。
The entire seat area is visible, so quick repairs
in-line can be made after removal of the bonnet assembly. Minor seat damage
can be removed by lapping, and major damage can be repaired with portable
boring tools. The pressure seal area can also be refinished with a simple
honing tool.
Y型
Y-Pattern
备有Y型截止阀，截流阀，截止止回阀和活塞止回阀供用户选择（参阅32和33页）。
Globe, stop, globe stop check and piston check
valves are also available in Y-pattern style (see pages 32
and 33). |
