Precision electric actuators
New motor control technology combines position accuracy with battery backup and continuous duty capability.
Valvcon ADC series electric actuators provide increased positioning resolution and torque, along with new processor control technology. Coupled with constant charge internal batteries, the new motor control technology provides positioning accuracy greater than 0.5% and continued operation after the loss of line power. The rugged, compact quarter-turn electric actuators are designed for use with PLCs and control systems requiring constant movement and high duty cycle.
Standard features include hardened steel gears, standard ISO5211 mounting interfaces, stall protection and a sleep/wake mode to preserve battery power. The actuators also have signal-fail position options, switch selectable power loss position, on-board manual control, battery status indication and up to 10 full cycles after loss of line power.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
