Launched in March, the E2HR Series Electro-Hydraulic Rotary valve actuators (photo) feature a very small installation envelope for¼-turn valve-actuating applications. All hydraulic components and sensors are integrated into a single compact manifold block that also houses the actuator and integral oil reservoir. The control panel can be mounted directly to the manifold block or installed remotely to run multiple units from a single control panel. This self-contained actuator can be installed either vertically or horizontally and has no external piping. It is available for on/off or modulating applications and for a wide range of markets and valve applications. The valves’ operating-temperature range is –50 to 40°C, and they offer very low power consumption and tight shutoff. — Cowan Dynamics, Inc., Montreal, Quebec, Canada
