The complete system is self-contained which eliminates the need for separated hydraulic power unit, simplifying the system construction and improving safety and reliability.

Using helical gear technology provides very high force-density and achieves the most compact solution to generate torque (comparing to rack & pinion and scotch yoke rotary actuators).

 The updated brochure provides engineers with:

  • Details on How to Configure Multiple E2HR Actuators
  • Mounting Flange Specifications & Dimensions
  • Bore Size / Motor / Torque / Speed Specifications
  • Easy How to Order Chart

Controlling Multiple E2HR Actuators

  • The E2HR control panel can be mounted remotely and control multiple valves thereby providing significant cost savings.
  • It is ideal for hazardous area locations and gives plant technicians the flexibility to mount the control panel in a safe zone.
  • Valve performance data for multiple valves can be accessed from a single control panel or access remotely.

Key Features of the E2HR Electro-hydraulic Rotary Actuator:

  • Torque up to 300,000 in-lb
  • Hydraulic Manual Override
  • Rotation: 90° +/- 5°
  • Speed 20°/Sec
  • ESD (Emergency Shut-down) Capable
  • Remote Diagnostics/Data logging
  • -50C to +40C Operating Temp.

Smart End Position Monitoring for Manually Operated Valves

13.03.2019 -

Auma offers a new sensor system for signalling valve end positions which can be mounted to the company’s GS .3 part-turn gearboxes. The new solution allows plant operators to monitor the position of manually operated valves, and hence to collect crucial valve position information from all the valves in their plants – not just from motor-operated valves, which mostly use the integral limit switching functionalities of the actuators.
