DRG Series Heavy-Duty Pneumatic Actuator
1. DRG spring return actuator can provide 120000 n. m torque output, DNG double acting actuator can provide 240000 n. m torque output. The maximum working pressure is 8 bar.
2. Two independent travel adjustment bolts, can be in the range of ±6℃ to regulate valve switch position.
3. Working temperature:
Standard (-20℃ ~ 80℃)
Low temperature (Down to -40℃)
High temperature (Up to 150℃)
4. Comply with IP65 protection class.
1. DRG Series heavy duty pneumatic Actuators are designed to perform in the most demanding applications. They are engineered to automate all types of quarter turn valves (ball, butterfly, plug and damper) with multiple torque profiles available for every situation.
2. DRG01 series is equipped with a SYMMETRIC design yoke that produces maximum torques at both ends of the stroke (0°and 90°) and minimal in the middle, therefore this series is the optimal solution for metal seated ball valves, plug valves and for modulating service.
3. Modular design and construction resulting in flexibility and interchangeability.
4. Using technology of plating hard chromium, which can ensure longer service life.
5. DRG02 series is equipped with a CANTED design yoke that produces a higher maximum torque at the beginning of stroke (i.e. valve unseating/reseating at 0°) and less torque at the end of stroke (90°), therefore this series is optimal solution for high performance butterfly valves.
6. Pathway high-frequency quenching grinding treatment, sliding block using self-lubricating technology, which can ensure permanent usability.
7. DEG series actuators come along with a complete line of controls and monitoring including Manual Handwheel (jacks-row), hydraulic overrides, limit switches, solenoid valve, positioners and other controls accessories.
