Explosion-proof electric pneumatic valve ball EXDII CT4 for required working condition of explosion proof standard grades of inflammable and explosive occasions of Exd Ⅱ CT4 refers to the explosive-proof grade to C, relative to the general use of occasions is B explosion-proof (
ExdⅡbT4)
Higher request, class C explosion-proof motor, commonly used in gas explosion, is made of cast iron or steel plate welded casing of the motor.
EXDII CT4 explosion-proof electric pneumatic valve ball electrical components requirements do fire prevention, anti-static processing, and achieve explosion-proof standard, commonly used in medium, such as liquid or gas, coal, petroleum, chemical industry, such as working conditions, by a 380 v / 220 v / 110 v ac power supply for driving power supply, with 4 - Or 0 to 20 ma current signal 10 v DC voltage signal to control signal, can make the pneumatic valve movement to the required position, to achieve its medium in the pipeline flow parameters such as size, pressure, temperature automatic control or switch control.
EXDII CT4 explosion-proof electric pneumatic valve ball performance characteristics:
1, shell, shell is hard aluminum alloy, the anodic oxidation process and polyester powder coating, corrosion resistance is strong, protection grade for IP67, NEMA4 and 6, and there are IP68 and explosion-proof type for choice.
2, motor: fully enclosed squirrel-cage motor, small size, large torque, inertia force is small, insulation class is F, built-in overheat protection switch, can prevent the damage to the motor overheating.
3, manual structure: the design of hand wheel to ensure safe and reliable, energy saving, small volume. No electricity, throw the clutch handle manual operation can be performed. Electricity, automatic reset of the clutch. （ Note: under the condition of the motor without power, electric actuators will remain permanent state of manual)
4, indicator, indicator is installed on the central axis, can look for the pneumatic valve position. Mirror convex lens design, no water, it is more convenient to observe.
5, dryer, used to control the temperature, prevent due to changes in temperature and weather actuator internal moisture condensation, maintain internal electrical components of dry.
6, limit switch: mechanical, electronic double spacing. Mechanical limit screw is adjustable, safe and reliable; Electronic limit switch controlled by CAM mechanism, easy adjustment institutions can set position accurately and conveniently, without the battery. ( The micro switch contacts are silver contact)
7, the torque switch: can provide overload protection, unsmooth in pneumatic valve, a foreign body, automatically disconnect the motor power, the more effective protection of pneumatic valves and electric actuators from being damaged. （ User has been set before delivery, please don't change the Settings)
8, self-locking: precision of double worm and worm wheel mechanism to efficiently transport large torque, high efficiency, low noise, Maximum 50 db) , long service life with self-locking function, prevent reversal, stable and reliable transmission parts, the factory has been filled with efficient grease, use need not go.
9, prevent to take off the bolt: when the demolition of the shell, bolt attached to the shell, will not fall off. External bolt adopt stainless steel material.
10, installation: installed with ISO5211 international standard size, at the bottom of the drive axle housing can be removed according to the need to carry on the processing, strong adaptability. Can be installed in a vertical or horizontal installation.
11, circuit, control circuit conforms to the single-phase or three-phase power supply standard, line layout reasonable, compact terminals can effectively satisfy the requirements of a variety of additional functions. Pneumatic valve switch in place any source contact output ( According to the customer request shall be processed separately. ）
12, intelligent module: using high integration, low power consumption MCU mixed with analog circuit control board, mounted with metal case more, make the actuator motor heat source and effective separation control panel, greatly improved the software and hardware anti-interference performance and temperature resistance.
13, pneumatic valve position digital display: the actuators in the process of opening or closing, the change of the pneumatic valve position in large digital real-time display on the LCD panel.
14, phase sequence automatically adjust: intelligent actuators automatically detect access of three-phase power phase sequence, phase sequence of three-phase power supply without user consider.
