PNEUMATIC ACTUATOR EB-SYD,DOUBLE ACTING - 1

PNEUMATIC ACTUATOR EB-SYD, DOUBLE ACTING TECHNICAL DATA Torque: exactly adjustable between -8°/+3° Limit switches and solenoid valve mounting: VDI / VDE 3845 Supply pressure: Supply quality: Filtered compressed air dry or lubricated. The pressure condensation point in accordance with (ISO 8573-1:2010, Class 3) has to be ≥ - 20°C or 10°C under ambient temperature. The maximum particle size in accordance with (ISO 8573-1:2010, Class 5) should not exceed 40 µm. For cycles ≥ 4 /min please lubricate. Temperature range: -20°C to +80°C (standard) -40°C to +80°C (low temperature) -15°C to +120°C (high temperature) The double acting version of this series is available in 13 sizes, constructed to the scotch-yoke principle. Valve interface: Actuator cylinder: Anodized aluminium, Other coatings upon request. FEATURES - Maintenance-free - Suitable for all ¼ turn valves - Blow-out proofed shaft - Torques in agreement with EN ISO 5211 - Optical position indicator with integrated operator for limit switches - All fasteners made of stainless steel - SIL 2 (SIL 3 as redundant system) acc. to IEC 61508 KEY BENEFITS - High opening- and closing- torques provided by scotch-yoke concept - Ideal sliding properties provided by low friction multiple piston guides - Operational safety and long service life assured by precise machining of parts - Low air consumption - ATEX: EX II 2 GD c Tx The EBRO Speed Control block allows the adjustment of closing/ opening times up to 60 sec. (depending on actuator size). It can be mounted directly onto the actuator.

PNEUMATIC ACTUATOR EB-SYD,DOUBLE ACTING - 5

PNEUMATIC ACTUATOR EB-SYD, DOUBLE ACTING FUNCTION Open When the left control connection is pressurized, the pistons are the yoke turns clockwise to close the valve. pushed together with the yoke turning counter-clockwise to open The stroke of the piston can be limited by adjusting the screws the valve. When the right control connection is pressurized, Subject to change without notice Especially non-lubricant media (e.g. bulk goods and dry gases) may cause an increasement of the valve torque. Choosing an actuator in critical limits, please contact our engineers. The torques shown in the...
