SPECIFICATIONS参数
Seat Rating 阀座等级
阀座等级基于阀瓣全关状态下的不同压力，仅适用于阀座。不同材料的阀体最大工作压力和检测压力显示于下列阀体压力等级表
这些等级是常规介质的保守性指导。过往流体经验或新的发展以及其他阀体材料或可允许高于下述压力的应用。具体推荐请咨询美卓公司总部。
Note ：
Type 860 and Type F860 valves are rated for a maximum differential pressure of 1000 psi (68.95bar) when installed in the non ‐preferred flow direction (shaft ‐upstream).
Type 860 and Type F860 valves with 316 stainless steel shafts are rated for a maximum differential pressure of 1000 psi (68.95 bar) in either installation direction.
