Alicat Scientific Inc. has introduced the Miniature Electric Valve Actuator Model (MEVA) for small rotary ball valves. The MEVA100, weighing only 1.7 pounds, features a sliding connection to the valve to prevent leaks due to seal failure (no lateral forces), saving torque for turning the valve rather than creating unwanted destructive friction in the transfer of energy to the valve stem. Designed for panel mounting, the MEVA100 can be retrofitted to both on/off and multi-position type valves. The MEVA100 includes high precision valve positioning along with a position feedback signal resulting in greatly improved and repeatable control performance.
