Product Description

Electric wafer segmented ball valve introduction
Electric wafer segmented ball valve equipped with electric actuator, control operation can be achieved by inputting control signal (4-20mA DC) and single-phase power supply, Electric wafer segmented ball valve to realize the adjustment of pressure, flow rate, temperature, liquid level and other parameters.V-cut on the Electric wafer segmented ball valve core, and the hard seal seat rotation generated shear force, fiber can be cut off, to prevent stuck.The Electric wafer segmented ball valve has the characteristics of circulation ability, high adjusting precision, large adjustable ratio, good sealing and light weight.Electric wafer segmented ball valve is suitable for most occasions except for small diameter, Angle type, three-way connection, it is the substitute for imported products, especially suitable for mud and medium containing fiber, and medium containing micro solid suspended matter.Electric wafer segmented ball valve is widely used in automatic control system of industrial process in paper industry, sugar industry, petroleum industry, chemical industry, metallurgy industry, etc.

Electric wafer segmented ball valve feature
1. The Electric wafer segmented ball valve body integral structure: sandwich-type and flanged V-type ball valve body is the overall side of the structure, strong structural rigidity, is not easy to cause deformation and leakage.
2. Upper and lower self-lubricating bearings: upper and lower self-lubricating bearings are installed in the valve body, with large contact area with the ball valve stem, high bearing capacity, small friction coefficient, so that the valve torque is reduced.
3. The Electric wafer segmented ball valve seat can be selected as metal hard seal or PTFE soft seal according to the needs of medium and working condition: hard alloy is surfacing on the surface of metal hard seal valve seat, and hard chrome is plated on the surface of ball or used for spray welding, ion nitriding and other hardening treatment, so as to enhance the service life and temperature resistance of the sealing surface;Soft seal PTFE seat or enhanced PTFE seat has good sealing, corrosion resistance and wide range of adaptability.
4. Economic practicality: light weight of valve body, small stem torque, equipped with pneumatic or electric actuator corresponding specifications small, compared with other types of control valves, cost-effective.
5. The medium adaptation range is wide: because of the Shear force between the V-shaped opening and the seat, and the smooth round of the valve chamber flow, the medium is not easy to store in the chamber, so Electric wafer segmented ball valve is suitable for liquid medium, more suitable for the system control with fiber and solid particulate medium.
6. Small flow control: through the small diameter spool special V-opening processing, can achieve small Cv value control.
