Definition of electric butterfly valve:
It is one of the most commonly used valves in industrial pipelines. The butterfly valve is small in size, less in material consumption, light in weight and larger in diameter, which is more economical than other valves. The electric actuator rotates 90 ° slowly, which is easy to operate. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small. When the opening degree is between about 15 ° and 70 °, sensitive flow control can be carried out. Therefore, the butterfly valve has great advantages in flow regulation of large diameter. It is not applicable to process media with particles and high temperature.
Definition of electric gate valve:
The opening and closing part of the valve is the ram. The movement direction of the ram is perpendicular to the fluid direction. The gate valve can only be fully opened and closed, not suitable for regulation and throttling. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used wedge gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 5o. Most gate valves are forced sealed, that is, when the valve is closed, the gate plate shall be forced to the valve seat by external force to ensure the tightness of the sealing surface.
Difference:
one Angle travel valve with 0-90 degree rotation, specific and good flow characteristics, small size, high cost performance
2. The electric gate valve moves up and down in a straight stroke control mode, which can be used as a shut-off valve. It is large in size and expensive
3 It can not be used under high temperature and pressure conditions, and is not wear-resistant. The electric gate valve is generally used to close the medium with granular materials, and is suitable for high-temperature and high-pressure conditions
