Soft Seal Butterfly Valve
Flow Control Wafer Type Butterfly Valve uses the integration structure, it can be operated by the input single (4 ~ 20 mA DC, 0 to 10 v DC or1-5 v) and the single-phase power supply, it has strong function, small volume, light and pleasant, reliable performance, simple, large flow capacity, etc. The valve is widely used in the automatic control system of food, environmental protection, light industry, petroleum, paper, chemical, teaching and research equipment, power and other industries.
Basic Parameters
DKJ-D (DY-J) series electric actuator is an allelectronic new product successfully developed by our plant on the basis of the ordinary type DKJ electric actuator by absorbing foreign advanced technology and applying new foreign technology and new devices, and it has intelligent functions with integration of control circuit and the mechanism. DKJ-D(DY-J) type electric actuator can directly accept DCS from a computer or 420mA or 1-5V from various regulating units, automatically control various dampers, valves, baffles and othe regulating mechanisms without additional configuration of servo amplifier, and it can be widely applied to power stations, metallurgy, petroleum, chemical and other industries. DKJ-D (DY-J) series electric actuator has the field manual function, so that the actuator can be adjusted in the field. If provided with DFD type electric Manipulator, it can complete undisturbed switching of "Manual-Automatic" of the remote regulating system
Product Show
DKJ series of quarter-turn electric actuator is a terminal control equipment of industry process measurement and control system. It can convert the system control signal into the angular displacement of output shaft so as to control the position of valve throttling parts or other regulating mechanism, then let the controlled medium operated according to the system prescriptive status.
Electric actuator can be divided into proportional type and integration type regarding to its control feature.The proportional type actuator is composed by electric servo amplifier and integration actuator. It can compare the system control signal with output shaft position feedback signal to change the travel distance of output shaft and let it has a proportional relation with input signal. Integration type actuator made of servo motor, reducer and position transmitter. lt can achieve the remote operation of valve or other regulating mechanism by matching the electric manipulator.
