ZAJV electronic motorized V type adjustable ball valve is matched with LKR series motorized actuator, not need to be matched with servo amplifier. If there is control signal(4-20mADC or 1-5ADC) and single phase power, it may be controlled and operated, so that the parameter of pressure, flow, temperature, hydraulic position can be adjusted. There is a V cutting on the valve core. It will rotate with hard sealing valve seat and produce the shearing force, which may cut off the fibre and avoid of blockage. Motorized V type adjustable ball valve is characterized by ventilated capacity, high adjusting precision, big adjustable ratio, good sealing and light weight etc. It is suitable for most conditions except in which there is small opening, angle type and three-way connection. It is the best product to replace the imported one, and it is especially suitable for the media of slurry, fibre and small solid floating material. It is widely used in the automatic control system of industry process of paper-making, sugar making, petroleum, chemical industry and metallurgy etc.
