VQ977F VQ977F-16 Electric wafer segment ball valve

Overview of VQ977F VQ977F-16 Electric wafer segment ball valve

VQ977F VQ977F-16 Electric wafer segment ball valve is used by the wafer type V-shaped ball valve together with the electric actuator. It does not need to be equipped with another servo amplifier. It can control the operation with input control signal (4-20madc or 1-5adc) and single-phase power supply. The electric V-shaped ball valve can adjust the parameters such as pressure, flow, temperature and liquid level. The valve core is provided with a V-shaped notch, which rotates relative to the hard sealing valve seat to produce shear force, which can cut off the fiber and prevent jamming. It has the characteristics of circulation capacity, high adjustment accuracy, large adjustable ratio, good sealing and light weight. It is suitable for most occasions except small diameter, angle and tee connection. It is the best product to replace imported products. It is especially suitable for the adjustment of mud, media containing fiber and media containing micro solid suspended solids. It is widely used in industrial process automatic control systems in paper industry, sugar industry, petroleum, chemical industry, metallurgy and other industries.

Working principle of  VQ977F VQ977F-16 Electric wafer segment ball valve

VQ977F VQ977F-16 Electric wafer segment ball valve adopts the ball core structure with V-shaped notch. When the valve is closed, it can cut the fibers and small particles in the medium. At the same time, because there is no gap rotation between the valve core and the valve seat, it can wipe the dirt on the ball and the valve seat by itself to maintain a good seal between the ball and the valve seat. The V-shaped ball valve adopts the valve seat structure loaded with spring or leaf spring. Due to the elastic restoring force of spring / leaf spring pushing the valve seat, it can have good sealing performance between the ball core and the valve seat for a long time. At the same time, because the valve seat adopts the spring-loaded movable structure, the valve seat can be automatically corrected to achieve the coincidence with the ball core.
