How Is The Electric Butterfly Valve Compared With The Electric Gate Valve?
- Nov 01, 2017 -

Electric butterfly valve definition:

Electric butterfly valve is one of the most commonly used valve types in industrial piping. Butterfly valve small size, less material, light weight, the greater the caliber relative to other valves more affordable. Electric actuator rotating 90 ° slow open, easy to operate. While the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop produced by the valve is very small and can be carried out when the opening degree is between about 15 ° and about 70 ° Sensitive flow control, so large diameter flow regulation, butterfly valve has a greater advantage. Not suitable for use in granules and high temperature in the process medium.

Electric gate valve definition:

Electric gate valve opening and closing parts is the gate, the direction of movement of the gate and the fluid direction perpendicular to the gate valve can only be fully open and fully closed, not suitable for regulation and throttling. The gate has two sealing surfaces. The two most commonly used wedge-shaped gate valves are wedge-shaped, and the wedge angle varies with the valve parameters, usually 5o. Most of the gate valve is forced to seal, that is, when the valve is closed, to rely on external force forced to the gate pressure to the valve seat to ensure that the sealing surface of the seal.

the difference: 

1 electric butterfly valve 0-90 degree rotation of the angle of the valve, the specific good flow characteristics, small size, cost-effective

2 electric gate valve up and down the movement of the straight stroke control, can be used as shut-off valve, bulky, expensive

3 electric butterfly valve can not be used for high temperature and high pressure conditions, not wear. Electric gate valve is generally used to carry the material with the media, suitable for high temperature and high pressure conditions
