Explosion - proof Electric Ball Valve Q941F
Explosion-proof electric ball valve angular travel explosion-proof electric actuator and ball ball composition, the actuator with integrated design, input 220V power supply can be directly switch adjustment, can also be built-in servo module, input control signal (4 ~ 20mADC or 1 ~ 5VDC ) And single-phase power supply to control the operation. Explosion-proof electric ball valve, explosion-proof grade d Ⅱ BT4, protection class IP67, with field control device. Explosion-proof electric ball valve main features: no power, pull the clutch handle can be manually operated. When energized, the clutch is automatically reset. Flow can be arbitrary, adjustable wide range, can be used for high pressure and large diameter occasions, control high viscosity, with fiber and fine particles of the medium. |
