burkert宝德 2658两位两通气动球阀,2658型球阀包括气动旋转式执行机构和一个塑料球阀阀体。执行机构与球阀间的连接为标准接口(法兰连接)。带线性 - 角度转换器的线性活塞使执行机产生旋转运动。旋转式执行机构使阀芯旋转90°,从而打开或关闭阀门。该紧型球阀适用于各种应用场合和介质。其气动旋转式执行机构也适用于其它阀体。2658 type ball valve including pneumatic rotary actuator and a plastic ball valve body. Between the actuator and valve connection to a standard interface (flange connection). With linear - Angle converter linear piston make the execution machine to produce rotary motion. Rotary actuator to valve core is rotated 90 °, so as to open or close the valve. The tight type ball valve is suitable for various applications and media. The pneumatic rotary actuator can also be applied to other body.
