4P/4H

The 4P/4H multi-turn actuators apply the reliable Planetary Torque Controls System (PTCS), fulfilling requirements in certain industries for actuators with a hydraulic or pneumatic supply in multi-turn applications with position and applied torque control.

• 4P pneumatic actuator: reversible vane motor including a wide range of supply pressures 2 to 7 bar
• 4H hydraulic actuator: reversible vane motor including a wide range of supply pressures 30 to 120 bar
• Torque from 450 Nm (332 lbf.ft) up to 200,000 Nm (147,556 lbf.ft) when combined with an external worm gearbox
• Multi-turn torque: 30 to 8,000 Nm (22 to 5,900 lbf.ft), combined with an external spur/bevel gearbox
• Linear thrust: 12 to 200 kN (2,697 to 44,961 lbf)
• PTCS patented planetary gearing system controlling the applied torque with high mechanical efficiency >95%
• Intrinsic mechanical torque limit protection
• Mechanical switch mechanism with a wide range of signalling options
• Lockable manual operation: motor drive priority
• Modular design, covering actuator with standard configuration up to actuator with control panels
• IP67/IP68, optional ATEX
• Environmental sealing. Optional double-sealed terminal compartment
