DN50 Motorized Water Ball Valve with F46 Seat Sealing
• This valve is operated by an electric signal coming from the electric motor to open, close, or stop the valve in the process of operation.
• Electric actuators feature visual and electrical valve position indication, manual override, and weatherproof enclosures.
• The position limit switch or torque switch signals stop at full open or close.
• The electric motor actuator is applied mainly to large size or high pressure valves because of greater torque over pneumatic actuator.
• This type has advantages of simple wiring and good response.
• In addition, a remote control is available, therefore the valve can be applied to a dangerous or limited space where it is difficult to access.
