'<br>Electric actuated ball valves is controlled either to be fully open or closed (or a combination of both) or modulating the valve position. A two-point or three-position control needs the motor control valve to first be turned on in order for it to fully open or fully close. The three-position control is more expensive and may require the use of a remote control.<br><br><br>A manual control valve requires only that it be turned on and then released; this allows the motor control to complete its normal functions and will not allow the motor to overheat or damage itself. Some of the electronic motor control valves are designed so that they will not allow the motor to overload and burn out, while others allow for a full closing/opening.<br><br><br>This type of control has a power switch that controls when the motor is turned on and off and which type of motor is used. It also has an indicator light that shows the status of the motor. It does not need a voltage converter or a high current source. It has an auto shut off function so that it does not turn on until the desired shut off point is reached.<br><br><br>The electronic electric actuator valves can operate at higher operating speeds and have a large variety of speeds, which will vary based on what type of motor is being operated. The speed control is usually located near the motor, but it can also be located at the top of the motor or on the shaft assembly itself.<br><br><br>Some electric actuator ball valves also come with a built-in heat-resistant shield that is able to protect the motor from overheating and damage. The shield is a plastic sleeve, which is placed over the ball bearing that is responsible for keeping the bearings from touching the heat shield and melting into each other. The heat shield prevents the heater fluid from heating up or warping the inner plastic sleeve, which is what causes the internal plastic parts of the heater to become damaged. The heat shield also protects the bearings from rusting.<br><br><br>The electronic ball valves are very reliable and are very easy to install and remove. However, they are not [https://www.shunchengvalve.com/hose-tap-ball-valve/ recommended] for installation where there is very hot or cold water to be heated or cooled or if you are operating a hot water system at the same time as the motor.<br>'
