BS858 product introduction:
The BS-858 series electric ball valve uses a permanent magnet reversible synchronous motor to drive a low-torque standard ball valve. The motor is energized only for a few seconds within the valve opening or closing process. The drive motor will be powered off automatically when the valve switch is in place.
