Designed to control pneumatic valves, Alfa Laval's ThinkTop is a control head with indication units and solenoid valves. It receives signals from a PLC to control the valve and sends feedback signals to the PLC to indicate the valve's position. Additional features include tolerance programs to ensure accurate feedback, self-adjustment to the tolerance band, built-in maintenance monitor and ability to maintain set-up during power failure.
