杠杆执行器
Lever Actuators
杠杆执行器可以配置在通径DN50~DN300的阀门上,适用于要求快速操作阀门,或者由于空间限制无法采用标准配置的手轮或锥齿轮执行器的应用场合。采用杠杆执行器要求阀门的最大压差不能超过下表所列的极限。这些最大压差是以各个通径阀门的操作力矩为基础计算的。
Lever actuators can be furnished on 2-12"
(DN50-DN300) valves for applications where rapid valve operation is required
or where space prevents use of a standard handwheel or bevel gear actuator.
Maximum pressure differential required for valves with lever actuators
should not exceed the limits listed. Maximums are based on the operating
force for each valve size.
订购时,请在主要阀门型号代码的上添加杠杆执行器代码。
To order, add the lever actuator code to the basic
valve order code.

手轮和链轮执行器
Handwheel and Chainwheel Actuators
所有通径DN50~DN600的阀门都可以配置手轮执行器,而所有通径DN50~DN500的阀门都可以配置链轮执行器。锥齿轮执行器可以应用在通径DN80~DN900的阀门上,还可以带手轮或链轮执行器。
All 2-24" (DN50-DN600) valves can be furnished
with handwheel actuators, and 2-20" (DN50-DN500) with chainwheel
actuators. Bevel gear actuators are available on 3-36" (DN80-DN900)
valves with handwheel or chainwheel actuators.
如果要订购手轮或链轮执行器,需要在主阀门订购代码的基础上添加适当的执行器订购代码。如果应用于干燥固体颗粒、造纸原料、泥浆或压力超过所标注的限制值时,请参阅锥齿轮执行器网页上的相关信息。链轮执行器所用的链轮需要另行订购。
To order handwheel or chainwheel actuators, add
the appropriate order code to the basic valve order code. Refer to information
on bevel gear actuators for use on dry solids, paper stock, slurries or
when pressure exceeds limits shown. Order chain for chainwheel actuators
as a separate item.
