Varnasan RA2.52SR Single Acting Pneumatic Actuator
Spring return mechanism ensures safe piston positioning even during power loss.
The Varnasan RA2.52SR Single Acting Pneumatic Actuator converts compressed air into linear motion for critical industrial automation duties. In addition, its integrated spring mechanism returns the piston to a safe position during power loss. Therefore, it is especially preferred for valve control and conveyor systems.
This actuator operates at PN 10 Bar nominal pressure and a maximum of 10 Bar with ATEX compliance. Moreover, the 52 mm piston diameter and cast iron body provide robustness and long service life. NBR and FKM seals enhance heat and moisture resistance, ensuring reliable operation in harsh environments. Consequently, maintenance intervals extend and operating costs decrease.
Varnasan RA2.52SR Single Acting Pneumatic Actuator — Technical Specifications
It is widely used in industrial valve automation, HVAC installations, and elevator safety systems. Furthermore, it is ideal for position control in palletizing and conveyor lines. Standard M5 and ISO 4401 connection ports allow easy integration with electrical control systems. In addition, ATEX 2014/34/EU certification enables safe operation in explosive atmospheres.
