Electric V-type ball valve features:
1. Electric V-type ball valve with AC220V, AC380V or DC24V power supply voltage as power, accept from DCS, PLC system or regulating instrument, operator input (4-20mA, 0-10mA or 1-5VDC) current signal or voltage signal, you can control the operation, RC, 381R, PSQ or HQ type electronic angular travel electric actuator, with internal servo operation and opening signal position feedback, position indication, manual operation and other functions, mechanical and electrical integration structure design, strong function, reliable performance, simple connection, small size, light weight, small flow resistance, large flow coefficient, simple structure, good sealing performance.
2. Angle travel electronic electric actuator is the driving device of V-type valve, it uses the power supply voltage as the power, accepts the unified standard signal (4-20mA, 0-10mA or 1-5VDC), converts this into the displacement corresponding to the input signal, changes the rotation Angle of the valve core (0-90º any Angle), so the corresponding Angle of the input signal, To achieve proportional action. The two-position switch type accepts AC220V or AC380V as the power, realizes the switching action through the positive and negative rotation of the motor, and outputs the valve position indication signal at the same time.
3. With excellent regulating characteristics: V-type valve has an approximate equal percentage of natural flow characteristics and up to 300:1 adjustable ratio.
4. Flow volume: because of its streamlined shape and full right Angle rotation control, the volume value is high, the flow capacity is particularly large, and the flow resistance is small, so you can use a smaller and more economical and practical valve size.
5. V-type valve adopts double bearing structure, high mechanical stability, small starting torque, to ensure that the valve has good sensitivity and induction speed.
6. Reliability: The valve body is an integral structure, the operation is not affected by pipeline pressure, and the valve body leakage can be avoided.
7. The sealing of the metal seat: The V-type valve uses the elastic movable metal seat, with self-compensation function, in the flow direction, the leakage is less than 10-5× rated flow coefficient. 
8. Shear capacity: When V-type valve adopts metal hard seal structure, V-type valve core and metal seat in the process of rotation, V-type notch and seat produce a strong shear force, which can cut off impurities such as fibers, and has self-cleaning function to avoid valve stuck phenomenon.
