功能介绍 Function introduction

进口防爆电动球阀(ExdIIBT4,BT6,CT4,CT5,CT6）执行器采用一体化设计，输入220V电源即可直接进行开关量调节，亦可内置伺服模块，输入控制信号(4～20mADC或1～5VDC)及单相电源即可控制运转。电动防爆球阀防爆等级为ExdIIBT4（BT6、CT4、CT5、CT6）、防护等级为IP67、可带现场控制装置。防爆型电动球阀主要特点为：不通电时，扳动离合器手柄可进行手动操作。通电时，离合器自动复位。流向可任意，可调范围广，能用于高压和大口径场合，控制高粘度，带有纤维和细颗粒的介质 RETZ The imported explosion-proof electric ball valve (ExdIIBT4, BT6, CT4, CT5, CT6) actuator is of integrated design. The switch value can be adjusted directly by inputting 220V power supply. The servo module can also be built in. The operation can be controlled by inputting control signal (4 ～ 20mADC or 1 ～ 5VDC) and single-phase power supply. The explosion-proof grade of the electric explosion-proof ball valve is ExdIIBT4 (BT6, CT4, CT5, CT6), the protection grade is IP67, and the field control device can be equipped. Explosion-proof electric ball valve is mainly characterized by manual operation by pulling the clutch handle when it is not powered on. When powered on, the clutch automatically resets. The flow direction can be arbitrary, and the adjustable range is wide. It can be used in high-pressure and large-diameter occasions to control the medium with high viscosity and fiber and fine particles
