The BV6 series butterfly valve can be remotely controlled by an actuator or manually operated by a handle
The actuator is available in three standard versions: Normally Closed (NC), Normally Open (NO) and Air/Air Activated (A/A). The actuator is designed so that the axial movement of the piston is converted into a 90° rotation of the shaft. When the valve disc contacts the sealing ring of the butterfly valve, the torque of the actuator increases. Valve closed
Selecting a manually operated handle can mechanically lock the valve in the open position\closed position\intermediate position and other positions, so the flow rate can be adjusted.
