Electrical Control Ball Valve
Electrical control ball valve is a rectangular structure of the advanced rotary control valve. Electrical control ball valve rotary, the structural composition consists of the rotary, angular, and electronic actuator valve and V shape valve, electrical control ball valve is powered by supply voltage, receiving the input of current signal and voltage signal coming from industrial automatic control instruments, it can achieve both the proportional control for fluid medium in the technical channel and two switch contact control. The design of Electrical control ball valve core carried with a special V shape notch, possessed with accurate flow characteristic and control function, it apply to control the media such as gases, liquid and solid particle. The valve core and valve seat of the electrical control ball valve are zero backlash, therefore, the valve has strong shear force and natural self-cleaning, electrical control ball valve is particularly appropriate for turbid liquid fibrous contained and tiny solid particle, as well as the automatic control system in solid granular working occasion.
Product feature: the motivation of electrical V shape ball valve is supply voltage---AC220V, AC380V, DC24V, it accepts current signal and voltage signal (4-20Ma, 0-10Ma or 1-5VDC) input from DCS and PLC system or regulating instrument, manipulator, it refers to control operation, adopt the structure of mechatronics, is has servo-operation system inside of the machine as well as the opening position feedback signal, position indication, manual manipulation functions, powerful function, dependable performance, quickly ligature, accurate control, small in size, light weight, small flow resistance, big folw coefficient, simple structure and good sealing property.
Rotary motional electric actuating mechanism is the actuating device of V shape valve, it is working by supply voltage, it takes the single standard signal (4-20mA、0-10mA or 1-5VDC), transforming it into correspondent displacement with incoming signal, altering the rotation angle of valve element ( arbitrarily between 0-90 ), hence, certain input signal is corresponding to certain corner to achieve proportional action. Two position switch receives AC220V OR AC380V to be activated, it realizes the on- off action by electrical machine’ shifting positively and negatively, and output valve position indication signal at the meantime.
Excellent regulating characteristic: V-type valve has a similar inherent equal percentage flow characteristic and adjustable up to 300:1 ratio. Therefore, V-type valve in the wide range of rate changes to provide precise control.
Maximum flow volume: Because of its streamline appearance and quarter-turn full control, it has a particular high in maximum volume, particular large in flow capacity, minimizing flow resistance, so we can use the smaller and more economic valve size.
V-valve dual-bearing structure, mechanical stability, high starting torque is small, to ensure the valve sensor with excellent sensitivity and speed.
The maximum reliable (safe) sex: Body as a whole structure, durable, not subject to pipeline operating pressures, and to avoid valve leakage.
Superior metal seat sealing: v-type valve adopts the elastic metal valve seat, has self-service compensate function, excellent sealing performance and long service life. On the flow direction, the leakage is equal or less than 10-5X rated flow coefficient.
Super shear capacity: v-type valve uses metal hard and seal structure, V and metal seated can create a strong shear force between valve seat and v-notch in the process of the rotary, it can cut off the fiber impurities, having self-cleaning function to avoid valve being stuck.
Summary of actuators: CR, HQ or PSQ angular travelling electronic electric actuators is the driving devices of electric V regulator, adopting the integration structure design, it takes AC220V supply voltage for the power, directly accepts unified standard signal (4-20 ma, 0-10 ma, or 1-5 VDC, 0-10 VDC), and turn it into the corresponding displacement of the input signals, moving by the angle (0 ~ 90 °), changing the opening valve core, so certain of the input signals is corresponding to a certain position, realizing the proportional action. Two switches accept AC220V or AC380V for power, it realizes the on- off action by electrical machine’ shifting positively and negatively, and output valve position indication signal at the meantime.
