They are available in 3” -24” (DN80 -600) sizes in wafer-style body design (860W) and in single-flange lugged design(860L) 860系列 600磅级高性能对夹式蝶阀关闭紧密，流通性能良好，使用寿 命长。3” -24” (DN80 -600) 之间有对夹式（860W）和单法兰凸耳式 （860L）。
含316不锈钢阀杆的860型和F860型阀门安装在任意方向，其额定最大压 差为1000psi。
流量参数 上述表格提供的是本册样本中860W和860L阀门的流量系数，Cv值代表 60°F的水的流通能力; 即流量系数。 公制Kv值等于Cv值乘于0.8569。 或者 Cv=1.167Kv。
Valve Body Ratings 阀体等级 These are maximum working pressure ratings of the Valve Body Only. These seat ratings above determine the practical pressure limitations according to actual service conditions. Test pressures below are for a hydrostatic test with the valve open. 下面是阀体的最大工作压力等级。上述阀座压力等级决定了实际使用工
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。 Seat Ratings for Series 860 Valves, Shaft Downstream 860系列阀门、阀杆

Valve Torque Data 阀门扭矩参数 The torque required to open or close Series 860 and F860 valves can easily be calculated using the equation below. However, for your convenience, the tables on page 4 can be used as a quick guide for actuator selection. If the valve’s torque is not listed I the tables, (use the equation to calculate the torque). Refer to Jamesbury bulletins for pneumatic and electric actuators. Select an actuator that provides the same or greater torque output than the valve’s torque. If in doubt, select the next larger actuator. Refer to these bulletins for pneumatic and electric actuator torque output valves and actuator selection tables. 启闭860 and F860系列阀门所需的扭矩很容易通过下列公式计算出来。 然而下一页（原文第四页）的表格可作为执行器快速选型指南。如果阀 门扭矩不在表中，则通过公式计算。参阅Jamesbury气动和电动执行器 的样本。选择比阀门扭矩相同或更大扭矩输出的执行器。 如有疑虑， 可选择再大一点的执行器。 气动和电动执行器的扭矩值和选型可参阅 下面的样本资料。 Manual Gear Actuators 手动齿轮箱 A100-1
