This new valve actuator takes up less space
Launched in March, the E2HR Series Electro-Hydraulic rotary valve actuators (photo) are said to pack high performance into the smallest possible 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. The actuator delivers a torque of up to 300,000 in-lb, has a duty cycle of 100% and can operate at temperatures from –50 to 40°C. Partial-stroke testing can be initiated from the touchscreen or remotely. — Cowan Dynamics, Inc., Montreal, Que., Canada
