Electric V-type ball valve, equipped with SX series actuator, without additional servo amplifier, input (4~20mADC or 1-5VDC) signal and single-phase power supply can control operation, to achieve the pressure, flow, temperature, liquid level and other parameters adjustment. There is a V-shaped incision on the spool, which is rotated relative to the hard-sealed valve to generate shear force, which can cut off the fiber and prevent stuck. It has the characteristics of flow capacity, high adjustment accuracy, large adjustable ratio, good sealing and light weight. Suitable for most occasions except small caliber, Angle, tee connection, is the best alternative to imported products, especially suitable for mud and containing fiber media, as well as containing small solid suspended matter medium adjustment. Widely used in paper, sugar, petroleum, chemical industry, metallurgy and other industrial automatic control system.
Structural characteristics
1.The introduction of German technology design simple structure, light weight, low material cost, than the same flow capacity of the direct stroke control valve is more economical.
2. Integral body without any fittings, so it is not affected by pipe or bolt stress, and because the body does not have any fittings, the pressure housing is not affected by pressure “sudden changes”.
3. The valve seat for leakage prevention is lined with stainless steel inner PTFE cup or O-type sealing ring at its outer diameter. The valve seat is made of tungsten cobalt carbide with a large section and is made of an alloy. The structure of the valve seat is further enhanced by an alloy corrugated spring.
4. With a V-shaped valve body, even in the case of small flow or high viscosity media, it can also ensure the accuracy of control in the entire range.
5. When the valve is closed, the wedge shear effect between the V-notch and the seat is generated, and it has a self-cleaning function to prevent the ball core from sticking, especially suitable for pipeline scaling and freezing, fibrous fluid, slurry fluid, high-viscosity fluid, including polymer, particulate matter, crystal and other fluid control occasions.
