Sanitary Butterfly Valve Notice

IRVINE, Calif. - Jan. 17, 2018 - PRLog -- The relationship between the opening of the butterfly valve and the flow rate changes substantially linearly. If used to control the flow, its flow characteristics and piping resistance is also closely related. If two pipes installed butterfly valve caliber, the same form and so on, and the pipeline loss factor is different, the butterfly valve flow difference will be great. If the butterfly valve is throttled at large amplitude, the back of the valve plate is prone to cavitate, which may damage the butterfly valve.

When the butterfly valve is in the middle of opening degree, the shape of the opening formed by the valve body and the front end of the butterfly valve takes the valve shaft as the center, and the two sides form a completely different state. One side of the front of the disc moves along the direction of flowing water, and the other side moves to the counter-current direction. Horizontal butterfly valve, especially large-diameter valve, due to water depth, the valve stem and the head of the difference between the torques cannot be ignored. In addition, the butterfly valve inlet side of the device will form a bias when the elbow, the torque will increase. When the butterfly valve is in the middle of opening degree, the operating mechanism needs to self-lock due to the flow of water.
