Selection points
Complies with ISO 15552 and VDMA 24562
The SN Series complies with ISO 15552 and VDMA 24562, facilitating actuator installation and selection according to common standards.
Micro-honed Extruded Aluminum Cylinder Tube
The SN Series features an extruded aluminum cylinder tube with micro-honed internal surfaces for reduced operating friction, making it suitable for valves and dampers requiring fast linear operation.
Adjustable Cushioning at Both Ends
The SN Series is equipped with adjustable cushioning at both ends, making it suitable for fast operating conditions where end-of-stroke impact of the linear actuator must be controlled.
Permanent Magnet as Standard
The SN Series is supplied with a permanent magnet as standard, making it suitable for automated valves and linear actuators requiring magnetic position detection.
Installation notes
Adjustment of End Cushions
Both ends of the SN Series cylinder are equipped with adjustable cushioning. During installation and commissioning, adjust each end separately to ensure smooth stopping at the end of the stroke and prevent impact.
FAQ
Which valves and control applications is the Neles Easyflow SN Series suitable for?
The SN Series is designed for fast operation of gate valves, globe valves, dampers, and other linear valves. Applications include plant automation, general process applications, high-cycle-life control and on-off applications, and emergency shutoff.
Which thrust and environmental parameters should be checked when selecting an SN Series actuator?
When selecting the actuator, verify the thrust required by the valve, operating pressure, ambient temperature, and protection requirements. The SN Series has a thrust range of 1147 to 20107 N, a maximum operating pressure of 10 bar, a temperature range of -20 to +80 °C, and an IP67 protection rating. Consult Neles for high-temperature or low-temperature versions.
What type of action does the SN Series use, and are spring-return versions available?
The SN Series is a pneumatic piston-cylinder linear actuator. The listed versions are double-acting. Consult Neles regarding spring-return versions; the listed double-acting versions must not be regarded as spring-return configurations.
What design features of the SN Series reduce friction and allow cushion adjustment?
The SN Series uses an extruded aluminum cylinder tube with micro-honed internal surfaces for low-friction operation. Adjustable cushioning is provided at both ends of the actuator, and each end can be adjusted separately.
Which standards do the SN Series mounting interfaces comply with?
The SN Series mounting interfaces comply with ISO 15552 and VDMA 24562. These two standards can be used as the basis for checking interface compatibility when mounting the valve and actuator.
