Usually with electronically controlled valves or any other device that has movement limits, there will be either a slotted ribbon, or 2 sensors and a stepper motor where the device can auto calibrate by moving until both sensors are hit, then it can calibrate it's self and move to a predetermined home position.
The same is with a ribbon, (a good example of that design is a printer where you will see it spin the feed wheels and move the heads from side to side on startup to calibrate it's self)
Usually electronically controlled valves do not need any user adjustment for calibration. (at least with heating and cooling systems)
air operated- spring return
A valve which requires pressurised air to operate (open or close) is known as pneumatic valve. A valve has a valve base through which the media (could be be air, liquid, steam, gas...) flows and a actuator mounted on the base which helps operate the valve. This actuator could be of pneumatic type. (or elctrically operated motorised type)
To adjust the ABB TZIDC positioner feedback for a pneumatic valve, first ensure that the valve and positioner are properly calibrated and installed. Access the positioner's configuration settings via the user interface or software, and adjust the feedback signal to match the valve's actual position. This may involve fine-tuning the span and zero settings, as well as verifying the input/output signal range. Finally, test the adjustments by moving the valve through its full range and confirming that the feedback accurately reflects the valve's position.

In case of emergency, if the cylinder stops, the motor does not. So it can be harmful for motor. Designers couple the high power motor to the cylinder of pump by means of a clutch. so the motor can continue to rotate while the cylinder stops. Also in case of closing the outlet valve of a pump, the pressure in the cylinder can fail the cylinder or crankshaft and accessories. in this case the clutch can separate the power from motor to the pump and prevent failure of pump.
The main function of a valve actuator is to control the valves ON to Close or modulating the valve,and the motor operated valve actuator is one important kind of valve actuator,the main different between kind valve actuators is it drive by electric power.
A motor-operated valve (MOV) works by using an electric motor to open or close a valve, controlling the flow of fluids in a system. The motor is connected to the valve mechanism, typically via a gearbox, which translates the motor's rotational motion into linear movement to operate the valve. Control signals from a control system determine the motor's actions, allowing for precise and automated regulation of fluid flow. MOVs are commonly used in industrial applications for their reliability and efficiency in managing fluid systems.
A solenoid valve is a electromechanically operated valve that is controlled by an electric current. It essentially controls the cylinders and fluid power in the motor of your Nissan Pathfinder.
The main difference between a MOV (Motor Operated Valve) and a ZV (Zone Valve) lies in their intended applications and functions. MOVs are typically used in industrial settings to control the flow of fluids or gases by using an electric motor to actuate the valve. On the other hand, ZVs are commonly used in HVAC systems to control the flow of water or steam to different zones within a building. Additionally, MOVs are usually larger and more robust, while ZVs are smaller and more compact due to their different purposes and environments of use.
motor is used as a actuator here. we can use globe,ball,butterfly type valves
If your EGR valve is vacuum operated, simply remove the vacuum hose from the valve.
what is the function of motor device
Good question Usually motor operated valve used in big pipe lines sizes which it is need strong torque and for ON/OFF condition not to control the process, We can use rather than M.O.V pneumatic ON/OFF valve with piston actuator (Double Acting) but in this case the accessories it will cost you more because you need to provide pneumatic amplifier and big actuator depend on the pipe size. That is why better to use M.O.V the motor will rotate the gears and the gears will rotate the valve with low cost. Contact me for more clarification if there is.
