Product overview
The electric V-shaped ball valve is equipped with LQ series actuator without additional servo amplifier. It can operate by inputting (4-20madc, 0-10vdc or 1-5vdc) signal and single-phase power supply to realize the adjustment of pressure, flow, temperature, liquid level and other parameters. 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, good sealing and light weight. It is suitable for most occasions except small caliber, angle and triangular connection. It is the best product to replace import and export products. It is especially suitable for the regulation of mud, medium containing fiber and medium containing micro solid suspension. It is widely used in industrial automatic control systems such as paper industry, sugar making, petroleum, chemical industry, metallurgy and so on.
Performance characteristics
• compact structure, small volume, vertical and horizontal installation, etc.
• a ball valve with excellent flow regulation characteristics of up to 1:300 and a similar percentage of V. Therefore, V-valve can provide accurate control in a wide range of changes.
• maximum flow volume: due to its streamlined shape and full right angle rotation control, the maximum volume is particularly high and the flow resistance is small. Therefore, a smaller, more economical and practical valve size can be used.
• V-type ball valve adopts double bearing structure, with high mechanical stability and small starting torque, which ensures excellent sensitivity and induction speed of the valve.
• superior sealing performance of metal valve seat: V-shaped ball valve adopts movable metal valve seat. Self compensation function, with superior sealing performance and long service life.
