Product overview of electric v - type regulating ball valve

Produced electric V type adjusting ball valve is composed of imported electric actuator and high quality V ball valve. Because the ball core has V-shaped structure, the valve seat has shear action. Therefore, the electric V-type regulating ball valve is suitable for controlling the relevant technological parameters in the suspensions medium containing fiber or tiny solid particles in papermaking, chemical, metallurgical and other industrial enterprises, especially in pulping, papermaking and selling. Automatic regulation of suspension particles, such as white water, black liquor, white liquid, and so on.

1. The V-notch ball core of electric V-shaped ball valve has shearing effect before metal seat, especially suitable for fibrous, Small solid particles, slurry and other mediums

2. electric V-shaped ball valve also has the ability to adjust and reliably locate, the flow characteristic is approximate percentage, the adjustable range is wide.

3. The electric V-shaped ball valve adopts the movable seat structure loaded by plate spring. The valve seat and the ball core will not produce problems such as blocking or detaching, the seal is reliable, the service life is long

Electric V-type adjusting ball valve product feature

Produced electric V type adjusting ball valve is composed of imported electric actuator and high quality V ball valve. Because the ball core has V-shaped structure, the valve seat has shear action. Therefore, the electric V-type regulating ball valve is suitable for controlling the relevant technological parameters in the suspensions medium containing fiber or tiny solid particles in papermaking, chemical, metallurgical and other industrial enterprises, especially in pulping, papermaking and selling. Automatic regulation of suspension particles, such as white water, black liquor, white liquid, and so on.

1, with elastic load pressure auxiliary seal seat to ensure the valve seat and ball core from the hard to end close contact.

2, with integral valve body structure, There is no possibility of potential leakage.

3, with equal percentage characteristics, wide control range and particularly stable control process, can be widely used in a variety of processes.

4, the stem and ball core using involute spline connection, When the tooth profile is loaded, the radial force on the tooth can play an automatic centering role, and the force on each tooth is uniform so that it has high strength and long life.
