EB5.1SYD EBRO pneumatic actuator is applied in general industries such as pharmaceuticals, OEM, Water and water treatment, petrochemicals, fire prevention, food processing, high and low temperature, marine engineering, transportation, mining.

The EB series pneumatic actuator is the flagship product of EBRO company, widely used in assembly with 1/4 turn valves such as butterfly valves, ball valves, and plug valves. The piston is precision cast, and the gear shaft is quenched and tempered nickel plated for efficient transmission. The cylinder body has been anodized to a thickness of over 30 μ m, with the addition of an epoxy polyester paint coating on the outer layer. The spindle has a groove free sealing design, which increases its lifespan by 2-3 times. The EB series is easy to install. The nominal diameter of the cylinder body ranges from Φ 32 to Φ 400, and there are 9 types of double acting models (EB4-EB280). The output torque range (under a pressure of 5 bar) is 5.9Nm to 8415Nm. It has passed ATEXT (TUV) CE and SIL safety certifications and can be used in harsh environments with high temperatures of 120 ℃ and low temperatures of -40 ℃.

EBRO's business in China has rapidly expanded, and its products have been widely used in many industries such as water supply and drainage engineering, electricity, petrochemicals, steel, coal mining, electronics, automobiles, municipal engineering, food and beverage.

The actuator and regulating mechanism of the EBRO pneumatic actuator are a unified whole, which includes membrane type, piston type, fork type, and gear rack type. Piston type with long stroke, suitable for situations requiring high thrust; The thin film type has a smaller stroke and can only directly drive the valve stem. Fork type pneumatic actuators have the characteristics of high torque, small space, and torque curves that better match the torque curve of valves, but they are not very aesthetically pleasing; Commonly used on valves with high torque. Gear and rack pneumatic actuators have the advantages of simple structure, smooth and reliable action, and safety and explosion prevention. They are widely used in production processes with high safety requirements such as power plants, chemicals, and refineries.

Working principle of EBRO actuator EB *. 1SYD in Germany:
When compressed air enters the pneumatic actuator from nozzle A, the gas pushes the double piston to move linearly towards both ends (cylinder head end), and the rack on the piston drives the gear on the rotating shaft to rotate counterclockwise by 90 degrees, and the valve is opened. At this time, the gas at both ends of the pneumatic actuator valve is discharged with the B nozzle. On the contrary, when compressed air enters the two ends of the pneumatic actuator from nozzle B, the gas pushes the double plug to move in a straight line towards the middle. The rack on the piston drives the gear on the rotating shaft to rotate clockwise by 90 degrees, and the valve is closed. At this point, the gas in the middle of the pneumatic actuator is discharged through nozzle A. The above is the standard transmission principle. According to user requirements, the pneumatic actuator can be installed with the opposite transmission principle to the standard type, that is, clockwise rotation of the selected shaft opens the valve, and counterclockwise rotation closes the valve. The A nozzle of the single acting (spring return type) pneumatic actuator serves as the air inlet, while the B nozzle serves as the exhaust port (the B nozzle should be equipped with a muffler). The intake of nozzle A is to open the valve, and when the gas is cut off, the valve is closed by the spring force.

Basic composition of German EBRO pneumatic actuator produced by the original factory
The types and structures of adjustment mechanisms for pneumatic actuators are roughly the same, mainly due to differences in the execution mechanisms. Therefore, the introduction of pneumatic actuators is divided into two parts: the actuator and the regulating valve. Pneumatic actuators consist of two parts: the actuator and the regulating valve (regulating mechanism). According to the magnitude of the control signal, generate corresponding thrust to push the regulating valve to operate. The regulating valve is the regulating part of the pneumatic actuator. Under the action of the actuator thrust, the regulating valve produces a certain displacement or angle, directly regulating the flow rate of the fluid.
