手动操作 MANUAL OPERATE

1.手动螺旋操作Manual Jackscrew Override

Sl系列直行程阀门驱动装置可以配带单向螺杆手轮手动装置，在紧急情况 下以及空气或电力出现故障时使用。单向螺杆手轮手动装置也可以用来使驱 动装置处于中间行程的一个特定位置。

The SL Series of linear valve actuators are available with a unidirectional manual jackscrew handwheel override for emergency use when plant air or power gas is unavailable. The override can also be used to hold the actuator in a particular position.

2.液压手动装置 Hydraulic Manual Override

对于要求推力高、安装单向螺杆手轮手动装置尺寸空间不允许或缺乏可操作 性时,可以使用液压手动操作机构。For models where a jackscrew override is not feasible due to high  thrust requirements, dimensional clearance or lack of accessibility, a manual hydraulic override is available

CTM阀门驱动装置可以配带一个液压手动装置（HY)， 双向为双作用， 单向为弹簧复位用,类型“FS”或“FR” The SL actuators are also available with a manual hydraulic override (-‘HY’), bidirectional for double-acting and unidirectional for spring-return, type‘FS’or‘FR’

液压手动装置也可以被用作起阻尼作用来精确地控制气缸速度。The override can also be used as a dampener for precise control of the cylinder speed.
