ball valve

Electric 3-way ball valve is composed by quarter-turn electric actuator and the 3-way ball valve, is a kind of rotary cutting, regulating valve, has closed tight, compact structure, light weight, convenient maintenance, etc.Electric three-way ball valve with single-phase 220 v alternating current (ac) as the source of power, accept the switch signal control system, through the single-phase power single-phase gear speed reducer drive reversible switch, make the ball valve according to the requirement to switch on line.Two seating electric 3-way ball valve has a compact structure, beautiful appearance, good seal performance, it can realize the flow direction of medium in the switch of the pipes, also can make the perpendicular two channel connected or shut down.Four seat tightness electric 3-way ball valve has a beautiful shape, compact and reasonable structure.It not only can realize the medium flow switch, also can make the three channels connected each other, now also can close any channel, make the other two channels connected, flexible control of the medium inside the pipeline rivers or shunt.Electric 3-way ball valve is suitable for water supply, petrochemical, metallurgy, mining, textile, energy, papermaking, food, such as steel pipe system in the flow direction of medium to switch and shunt for medium or mixed fluid.
The flow direction of medium electric 3-way ball valve principle
Three-way ball valve L type and T type, medium flow direction as below.L-type three-way ball valve is suitable for the medium flow switch, can make the two channels connected perpendicular: T tap, confluence of three-way ball valve is suitable for the medium or flow switch, T channel can make the three channels connected to each other or make two of them connected, the 3-way ball valve generally adopt two seat structure, can also according to user requirements adopted four seat structure.
Electric 3-way ball valve electrical parameters
Electric actuator type: optional PSQ, 3810 r, DTR quarter-turn actuators.Explosion-proof type selected 3810 series.
Please refer to the corresponding technical parameters and performance: the illustrations of the actuators and valve locator.
Adjustable control accuracy: 0.1% ~ 3.1%.
Receiving control signals: 0 ~ 10 ma. DC, 4 ~ 20 ma. DC or 1 ~ 5 v. DCv key choice: 1, the input signal is interrupted: interrupt mode (open, stop, close) 2, 3 are reverse action choice, choice of control accuracy.
Electric actuator full open and full closed position automatic positioning calibration, convenient and accurate.
According to the input signal and the electric actuator position where smart step adjustment automatic positioning, restrain oscillation with high precision.
Position signal output electric device: 4 ~ 20 ma. DC electric device full closed and open.
