Zajv electric V-type flange regulating ball valve pn16-pn40 is a kind of rotary ball valve with metal core seat or metal to PTFE seal fit. It combines the Zui good control characteristics of ball valve and butterfly valve, and can be used as control regulating valve and shut-off valve.
Zajv electric V-type ball valve is composed of yxr, PSQ electric actuator and V-type ball valve. It is an angular stroke control valve controlled by the V-notch spherical valve plate rotating close to the sealing surface in a small opening range.
The V-notch ball plate of the electric V-type ball valve can increase the regulating ratio and shear the sealing ring during the closure. Therefore, it is suitable for the control system with large regulation ratio and the control of fluid containing fiber and slurry.
Electric v-ball valve is widely used in petroleum, chemical, electric power, metallurgy, steel, paper, medicine, food, textile, light industry and other industries.

1. Be careful in installation and construction, and do not hit the valve.
2. Before installation, the ball valve should be inspected to check the specification and model, and identify whether there is damage, especially for the valve stem. Turn it a few times to see if it is skewed, because Zui is prone to bump the stem during transportation. Also remove the debris in the valve.
3. When lifting the ball valve, the rope should not be tied to the hand wheel or the valve stem to avoid damage to these parts, but should be tied to the valve body.
4. The pipeline connected to the ball valve must be cleaned. Compressed air can be used to blow away iron oxide chips, mud and sand, welding slag and other impurities. These debris, not only easy to scratch the sealing surface of the ball valve, in which large particles of debris (such as welding slag), but also block the small valve, so that its failure.
5. The position of valve handle rotation should be reserved during installation. 6. The ball valve cannot be used as throttling. 7. The ball valve with transmission mechanism shall be installed vertically.
