Product Highlights:
1. High-grade brass precision forging, the valve parts are compact:
2.Kvsu21m3/h is suitable for any size fan tray camp:
3. Straight water flow will never block the slag:
4. Large water circulation capacity, higher than traditional valve 3 or more
5. The valve is closed tightly and there is no internal leakage.
6. The drive will be powered off automatically after the valve is closed/opened. long lasting:
7. The closed structure is subject to gas intrusion. The motor runs reliably:
8. Can be mounted upright or horizontally
9. The failure rate is extremely low.
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.
