Application scenarios
High-torque open/close control of 90° quarter-turn valves
The EB-SYD pneumatic double-acting actuator drives 90° quarter-turn valves. Its scotch yoke mechanism delivers high opening and closing torque, with a rated torque range of 27-9768 Nm, making it suitable for valves with demanding open/close torque requirements.
Automation of 90° quarter-turn valves in explosive atmospheres
The EB-SYD provides pneumatic actuation for 90° quarter-turn valves in hazardous areas of explosive atmospheres and holds ATEX EX II 2 GD c Tx explosion-proof certification.
Valve actuation for safety instrumented functions
The EB-SYD can be used in applications where the valve actuator is integrated into a safety instrumented function, complying with IEC 61508 with SIL2 rating and optional SIL3.
Automation of 90° quarter-turn valves in low- or high-temperature conditions
Depending on site temperature, the low-temperature or high-temperature version of the EB-SYD can be selected: the low-temperature version operates from -40°C to +80°C and the high-temperature version from -15°C to +120°C, for driving 90° quarter-turn valves within the respective temperature ranges.
Valve position indication and limit switch status feedback
The EB-SYD features 360° position indication and integrated limit switch triggering; related accessories can be mounted via the VDI/VDE 3845 interface for position status feedback of 90° quarter-turn valves.
Selection points
Scotch yoke high-torque output design
The scotch yoke mechanism generates high output torque during valve opening and closing strokes, suitable for actuator selection for 90° quarter-turn valves.
Adjustable end-of-stroke limits
Stroke limits are adjustable within a range of -8° to +3°, allowing the actuator stroke to be fine-tuned to the actual end positions of the valve.
Graduated temperature range configurations
Available in standard (-20°C to +80°C), low-temperature (-40°C to +80°C), and high-temperature (-15°C to +120°C) configurations for selection according to ambient temperature conditions.
Functional safety and explosion-proof certification
The product meets the SIL2 safety integrity level of IEC 61508 with optional SIL3, and holds ATEX EX II 2 GD c Tx explosion-proof certification.
Marine-grade aluminum alloy and stainless steel connectors
The cylinder body is made of anodized marine-grade aluminum alloy with stainless steel connectors, suitable for industrial environments with specific actuator material and surface treatment requirements.
FAQ
What are the torque output characteristics of the EB-SYD pneumatic double-acting actuator, and can it meet the valve breakaway torque requirements during opening?
The actuator features a scotch yoke design that generates high output torque when opening and closing the valve. At 6 bar air supply pressure, its rated torque output range is 27 to 9768 Nm, making it suitable for driving 90° quarter-turn valves.
How suitable is the EB-SYD actuator for extreme temperature environments?
The series offers three operating temperature configurations to suit different conditions: the standard type operates from -20°C to +80°C; the low-temperature type from -40°C to +80°C; and the high-temperature type from -15°C to +120°C.
What is the stroke adjustment range of the EB-SYD actuator when special control accuracy is required?
The actuator features adjustable stroke limits with an adjustment range of -8° to +3°, enabling precise fine-tuning of the valve closed or open position.
What are the specific air supply quality requirements for this pneumatic actuator?
Air supply pressure must be between 2.5 bar and 8 bar. The air supply should be filtered dry or lubricated compressed air: solid particles must comply with ISO 8573-1:2010 Class 5, with a filtration rating of no less than 40 μm; moisture content must comply with Class 3, with a dew point ≥ -20°C or 10°C below ambient temperature. When the switching frequency is ≥ 4 cycles/minute, the air supply must be lubricated.
Which industrial safety and explosion-proof certification standards does the EB-SYD actuator meet?
The actuator complies with IEC 61508 with SIL2 safety integrity level (SIL3 optional). It also holds ATEX explosion-proof certification rated EX II 2 GD c Tx and can be used in designated hazardous areas.
