    Electric Gate Valve -FAQ

    What is the difference between the electric gate valve and the electric globe valve?

    In terms of route:

    The electric gate valve route is longer compared to the electric globe valve.

    In terms of flow resistance:

    When the electric gate valve opens completely, the whole channel for the flowing is unchecked. In similar timings, the pressure loss of the medium is at a minimum level. While compared to the electric globe valve, the electric gate valve’s actual benefit is the flow’s small resistance. In general, the flow resistance coefficient in an electric gate valve is approximately 0.08-0.12; in an electric globe, the valve is up to 3.5-4.5. So, you require less force to turn it on and off. The electric gate valve applies when you want to keep the gate board completely open or close. It is suitable when you are not using the electric gate valve regularly. The electric gate valve is inappropriate for controlling or adjusting purposes.

    The electric globe valve’s unbalancing force and flow resistance are significant in the process. So, the force corresponding to it is needed for the driving force or torque to be more considerable. Moreover, it is appropriate for controlling and adjusting the fluids. For the medium flowing along with the high speed, the partial opening of the gate can cause vibration and damage the sealing surface of the valve seat and gate. Besides that, the regulation can result in erosion of the gate from the medium.

    In terms of the flow direction:

    Whenever the globe valve is installed, the medium’s entry is through the core of the valve in two ways: one is from the bottom and another from the top. The benefit offered from the bottom is that the base is free from the pressure when the valve is closed. It increases the valve’s lifespan and makes easy replacement when the pipeline is ahead of the valve under pressure. But, here lies the disadvantage, which means large driving torque at this moment. The axial force on the valve stem is more significant, causing the stem to bend. Therefore, you can apply for the bottom entry only on a small calibre globe valve.

    The top entry is preferable to the electric gate valve for general purposes. The actual drawback of top-entry is precisely opposite to the top-entry. While the direction of the flow is from both sides, then the effect of the entry remains the same.

    In terms of the sealing surface:

    Whenever there is an opening and closing of the electric gate valve, the sealing surface of the valve seat and core are always in touch and rub one another. So, wearing the sealing surface is more accessible, especially when the electric gate valve is closed. The difference in pressure inside and outside the valve core is high, leading to scratches on the sealing surface. When there is an opening state of the valve disc in the electric globe valve, then no contact with the sealing surface. So, mechanically the wear is more minor. The electric gate valve can seal by itself. The contact of the valve core is along with the sealing surface of the valve seat through the pressure at the medium level. It helps in achieving the tightness of a high level. But, there are few solid particles in the medium that can cause damage to the sealing surface.

    The incline angle of the wedge electric gate valve core is mostly 3-6 degrees. Whenever you are closing the electric gate valve forcefully, the core gets stuck easily due to the significant temperature differences. It would help if you took specific measures for the high pressure and temperature to prevent the core from getting stuck. You can only seal the globe valve’s surface when you forcefully close it. Under these circumstances, the working pressure, driving of the device, and torque of the globe valve is 2.5-3.5 times more than the electric gate valve. So, you need to pay attention while adjusting the torque controlling mechanism of the electric globe valve.

    The sealing surfaces are always in contact with one another whenever there is a complete closing of the globe valve. There are fewer scratches on the sealing surfaces and more minor slips between the sealing surface, forcing the valve core’s closure. The wearing of the electric globe valve is usually due to the sealing surface and valve core wreckages. The speedy erosion of the medium can lead to the closing in a loose state.

    How to select the electric actuator for the electric gate valve?

    For the selection of the electric actuator for the electric gate valve, do consider the following points:

    · Working torque:

    It is the main factor when selecting the electric actuator for the electric gate valve. The output torque of the electric actuator needs to be 1.2-1.5 times for the working of the electric gate valve.

    · Ring number of the output shaft for the rotation:

    In this parameter, you have information about the average diameter of the electric gate valve, number of threading heads, and stem pitch.

    · Structure of operating the electric gate valve:

    It is of two types: the first is about not configuring the thrust disk and direct torque as an output. The second is about the configuration of the thrust disk, and output torque is from the thrust disk of the stem nut along with the conversion of the output thrust.

    · Output speed:

    If the opening and closing speed of the electric gate valve is very fast, then it is simpler to create water hammer occurrence. Therefore, depending on the different conditions of using the electric gate valve, you must select the suitable speed for closing and opening.

    · Stem diameter:

    The electrical actuator passing from the stem’s maximum diameter cannot pass from the rod of the electric gate valve. Moreover, the internal diameter of the output shaft of the electric actuator has to be more than the diameter of the outer stem gate valve. It would help if you considered the stem’s diameter and partially the gate valve’s rotation for selecting the electric actuator. It is for making the electric gate valve work in normal conditions.

    · Special requirements:

    There are special requirements of the electric actuator for the electric gate valve. You need to limit the axial force or torque. Its adoption is essential for the shaft connecting along with the limitation of the torque. While determining the specifications of the electric actuator, the controlling torque is equally essential. Generally, the electric actuator won’t get overloaded whenever you are operating for a particular period.

    Conditions leading to overloading the electric actuator:

    • First is the low power supply voltage; not receiving the desired torque can stop the electric actuator from working.
    • Adjusting and limiting the mechanism of the torque can lead to wrong adjustments. It is more than the stopping of the torque. As a result, there is a continuous generation of large torque, and the motor stops working.
    • The third condition is heat savings. It exceeds the permissible temperature.
    • If the surrounding temperature is very high, that decreases the thermal capability of the electric actuator.
    Protection methods to avoid overloading:
    • If your electric actuator is continuously in working condition, it is better to use the thermostats.
    • Using the thermal relays can protect the motor that is turning and plugging.
    • Using fuses or overcurrent relays helps avoid the accidents of short circuits.
