气动调节阀带法兰球阀
气动球阀开关由高精度气动执行器和精密铸造球阀组成。主要分为气动软密封球阀和气动金属密封球阀两种。气动开关球阀结构紧凑，体积小，运行可靠，流动阻力低，密封性好，维护方便，安装方便，适应性强等特点。
气动球阀与移动限位开关，电磁阀，减压阀和0.4 0.7 MPa气源匹配时可实现开关。并输出两个无源触点信号，以控制阀门打开或关闭。气动式O型球阀特别适用于粘稠的，含有颗粒和纤维性能的介质。气动开关球阀广泛应用于石油，化工，教学设备，轻工，高压设备，制药，造纸等工业自动化控制系统，作为长途集中控制或本地控制系统。
技术特点
多功能位置指示器，本地显示，符合标准VID / VIE3845，NAMUR，可安装和输出所有配件，如限位开关盒，电动定位器，定位传感器。
空气源端口符合NAMUR标准，并直接安装NAMUR标准电磁阀。
齿轮背面的复合轴承，活塞引导环和输出轴轴承是金属与金属的摩擦保护，使用寿命长。
所有固定材料均为不锈钢，防腐蚀。

Pneumatic Regulating Valve Ball Valve with flange
Pneumatic ball valve switch consist of high accuracy pneumatic actuator and precision casting ball valve. Mainly divided into pneumatic soft sealing ball valves and pneumatic metal sealed ball valve two types. Pneumatic switch ball valve has a compact structure, small volume, reliable operation, low coefficient of flow resistance, good sealing, easy maintenance, easy installation, strong adaptability, etc.
Pneumatic ball valve can realize on-off when matched with moving limit switch, solenoid valve, pressure reducing valve, and 0.4 0.7 MPa gas source. And output two passive contact signal to control valve on or off. Pneumatic type O shape ball valve is particularly suitable for medium which is viscous, containing particles and fiber properties. Pneumatic switch ball valve is widely used in petroleum, chemical industry, teaching equipment, light industry, high pressure equipment, pharmaceutical, paper and other industrial automatic control system, as long-distance centralized control or local control system.
Technical characteristics
Multifunction position indicator, local showing, conform to standard VID/VIE3845, NAMUR, can install and output all the accessories like limit switch box, electric positioner, location transducer.
Air source port conform to NAMUR standard, and install NAMUR standard solenoid valve directly.
Composite bearing, piston leading ring and Output shaft bearing at Gear back side is rubbing protection of metal to metal, long service life.
All fixing material is stainless steel, anticorrosive.
