Single Entry Valves - CAREFULLY tighten single Union Nut.
单进入阀门-小心紧固单活接头螺母。
Upon installation, a hand-tightened union nut serves to compress the face-seal of a Chemtrol valve.
在安装期间，手动紧固管接螺母用来压紧Chemtrol阀门的表面密封。
Upon installation, a hand-tightened union nut serves to compress the face-seal of a Chemtrol valve.
一旦安装完毕，手动旋紧的管接螺母就紧压着Chemtrol阀门的密封面。
Thus, by adjusting the tightness of the union nut, the squeeze of the seats against the ball would be maintained.
因此，在调节管接螺母的紧固度时，阀座对球体的压力就一直存在着。
Do not adjust the union nut with the handle in any position other than fully parallel or perpendicular to the body.
除非完全平行或垂直于阀体，或者不要在任何位置用手调整管接螺母。
Adjustment of this union nut can compensate for wear of TFE seats, with no production loss to remove valve for internal adjustment.
这种管接螺母的调整能够弥补TFE阀座的磨损，避免由于拆卸阀门进行内部调整作带来的损失。
