Product Overview:
Explosion proof electric ball valveThe angular stroke explosion-proof electric actuator and ball valve ball are composed of an integrated design. The actuator can directly adjust the switch quantity by inputting 220V power supply, and can also be equipped with a built-in servo module. The operation can be controlled by inputting control signals (4-20mADC or 1-5VDC) and single-phase power supply. Explosion proof electric ball valve, explosion-proof rating of dIIBT4, protection rating of IP67, with on-site control device. The main feature of explosion-proof electric ball valve is that when not powered, manual operation can be performed by pulling the clutch handle. When powered on, the clutch automatically resets. The flow direction can be arbitrary, the adjustable range is wide, and it can be used in high-pressure and large-diameter applications to control high viscosity media with fibers and fine particles.
