▊装配说明assembly instructions:

1、在180-55k或v)阀座塞螺纹上涂抹braycote 803润滑脂,并将其放入阀体中。

2、使用18r2-2阀杆,顺时针将阀座塞拧到固定位置。

3、将18r2-6密封垫圈放置在阀体顶部密封面上。

4、将18r2-14止推垫圈放入18r2-3a阀盖的凹槽中。

5、将18r2-3a阀盖总成顺时针拧到阀体上,直至固定位置。

6、将18r2-3a阀盖扭转至190英尺/磅。

7、安装180-5手柄、306-11弹簧和306-17螺母。

注:阀盖组件采用bracote 803预润滑。如果需要额外润滑使用braycote 803。卤代碳不是一种可接受的t形密封杆润滑剂。

1. apply braycote 803 grease to the 180-55k or v) seat plug thread and place in body.

2. using the 18r2-2 stem, screw the seat plug clockwise to seated position.

3. place 18r2-6 seal washer on top valve body sealing surface.

4. place the 18r2-14 thrust washer into groove of 18r2-3a bonnet.

5. screw 18r2-3a bonnet assembly over valve body clockwise to seated position.

6. torque 18r2-3a bonnet to 190 ft/lbs.

7. install 180-5 handle, 306-11 spring, and 306-17 nut.

note: the bonnet assembly is pre- lubed with bracote 803. if additional lubrication is required

use braycote 803. halocarbon is not an acceptable lubricant for the rod t-seal.
