Oxygen control valves consist of valve , actuator and accessories 氧气调节阀由阀门,气动执行机构及附件组成
Pneumatic rotary actuator 角行程气动执行机构
Pneumatic valves regulate the pneumatic enforcement agencies and regulatory valves two 气动调节阀由气动执行机构和调节阀两部组成。
The most commonly - used cylinders are actuated by air , but oil and water types are also available if required 最常用的缸体执行机构是气动执行机构,但是如果需要,也可提供油动或水动执行机构。
Large specification of pneumatic operation organ and manual organ . if users have special requirements , we can make according to the provided data 大规格气动执行机构与手动机构,如用户有特殊要求,可提供数据定制。
Nibco electric actuators , and nda and nsr pneumatic actuators feature iso standard mount and drive ( exception is 800 series ) 美国尼伯科电动执行机构,和nda和nsr气动执行机构具有iso标准安装和驱动( 800系列除外) 。
Note : if special features are required for actuators such as modulating positioners either for electric or pneumatic actuators , consult factory 注意:如果要求执行机构具备特别的性能,如用于电动或气动执行机构的调制位置调节器,请咨询工厂。
Ideally suited for most quarter - turn valves , nibco nda and nsr pneumatic actuators offer exceptional starting and ending torque in a compact design 适用于大多数角行程阀门,使用程度理想,美国尼伯科nda和nsr气动执行机构在紧凑的结构里提供非常的开启和关闭扭矩。
Hole of nominal size connects with pneumatic operation organ , threr is a square body protruding out which directly connects with the internal octagon of pneumatic operation organ 标准尺寸的孔与气动执行机构连接。中间为一伸出体外的方身,直接与气动执行机构内八角相连。
Under certain service conditions or when valves are equipped with cylinders or electric motor actuators , there may be a cost advantage in designing and installing the valves with flow over the disc 在某种应用条件下,或者当阀门配置气动执行机构或电动执行机构时,在安装阀门时使得流进的流体位于阀瓣上方可能具有成本较低的优点。
