Subject to change without notice - 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
The torques shown in the diagram are measured values. The
required size of the actuator can be established by comparing the
values of the actuator with the required torque of the valve. KEY BENEFITS
Especially non-lubricant media (e.g. bulk goods and dry gases) may - High opening- and closing- torques provided by scotch-yoke
Effective torque in Nm → guides
cause an increasement of the valve torque. Choosing an actuator in
critical limits, please contact our engineers. concept
- Ideal sliding properties provided by low friction multiple piston

- 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.
