(对夹式)进口气动超薄型球阀 执行器参数 Actuator parameters

采用双作用式和单作用式(弹簧复位)气动执行器,齿轮齿条传动,安全可靠;大口径阀门采用系列AW型气动执行器拔叉式传动,结构合理,输出扭矩大  Double acting and single acting (spring return) pneumatic actuators are used for rack and pinion transmission, which is safe and reliable; The large diameter valve adopts series AW pneumatic actuator fork type transmission, with reasonable structure and large output torque

1、齿轮式双活塞,输出力矩大,体积小 Gear type double piston, large output torque, small volume

2、可在顶部、底部安装手动操作机构 Manual operating mechanism can be installed at the top and bottom

3、齿条式连接可调节开启角度、额定流量 Rack type connection can adjust opening angle and rated flow

4、执行器可选带电讯号反馈指示及各类附件以实现自动化操作 The actuator can select live signal feedback indication and various accessories to realize automatic operation

5、IS05211标准连接为产品的安装更换提供了方便 IS05211 standard connection provides convenience for product installation and replacement

6、两端调的节螺钉可使标准产品在0°和90°有±4°的可调范围。确保与阀门的同步精度 The adjustable pitch screws at both ends can make the standard products have an adjustable range of ± 4 ° at 0 ° and 90 °. Ensure synchronization accuracy with the valve
