表中所有扭矩都是在15.5摄氏度水温状态下测试取得。对于干燥气体状态下的扭矩，请用1.6乘于这些数据。如果需要了解其他流体介质状态下的扭矩，请与我们联系。
　　All torques shown in these charts were derived from test data using water at 60°F. For torques using dry gases, multiply these numbers by 1.6. For torques involving other media, please consult the factory.

　　这些表各种的数据并没有考虑安全因素。关于执行机构的规格，美国克雷恩建议对于单个阀门上的执行机构，用1.2乘于表中的数据；对于三通（T型）结构应用场合，则需用1.5乘于表中数据。
　　There is no safety factor included in the numbers shown on these charts. For actuator sizing, Crane recommends that these values be multiplied by 1.2 for single valve applications, or 1.5 for 3-way ("tee") applications.

　　对于聚四氟乙烯（PTFE）阀座，请用2.0乘于表中的数据。
　　For PTFE seats multiply the numbers shown on this chart by 2.0.

　　在某些条件下，水动力扭矩可能达到或超过阀座和非阀座扭矩。在设计阀门系统时，必须考虑水动力扭矩，这样有助于正确选择所需阀门产品。
　　Under certain conditions, hydrodynamic torque can meet or exceed seating and unseating torques. When designing valve systems, hydrodynamic torque must be considered to help assure correct selection for the application.

　　阀座材料能够承受低温环境的考验而不会被损坏。但是，弹性材料会变硬，扭矩也会增加。有些流体介质可能会进一步限制所公布的温度范围，并且/或者明显缩短阀座使用寿命。
　　Seat materials are capable of withstanding lower temperatures without damage. However, the elastomer becomes hard and torques increase. Some flow media may further restrict the published temperature limits and/or significantly reduce seat life.
