FAQ
Which valves and strokes is the EB-SYS pneumatic single-acting actuator suitable for?
The EB-SYS is suitable for quarter-turn valves with a valve connection interface compliant with EN ISO 5211. Its output torque range is 35–3590 Nm; actuator sizing should match the torque required by the valve during opening, closing, and actual operating conditions.
What are the air supply pressure and compressed air quality requirements for the EB-SYS single-acting actuator?
The air supply pressure range of this actuator is 2.5–8 bar. The compressed air may be filtered dry air or lubricated air; per ISO 8573-1:2010, the air quality must meet Class 3, with a dew point of at least -20°C or 10°C below the ambient temperature, and filtration must meet Class 5 with a rating of no less than 40 μm. When the switching frequency reaches or exceeds 4 cycles per minute, the compressed air must be lubricated.
Within what ambient temperature range can the EB-SYS be used?
The EB-SYS standard version has an operating temperature range of -20°C to +80°C; the low-temperature version is rated -40°C to +80°C; the high-temperature version is rated -15°C to +120°C. The appropriate version should be selected according to the minimum and maximum ambient temperatures at the installation site and the compressed air conditions.
How are valve position travel stops and accessory mounting handled on the EB-SYS?
The travel stops of this actuator are adjustable within -8° to +3°, allowing correction of the end positions of quarter-turn valves. The actuator is equipped with 360° position indication and integrated limit switch triggering; the limit switch and solenoid valve mounting interfaces comply with VDI/VDE 3845.
What features does the EB-SYS offer for safety and explosion-proof applications?
