Alfa Laval ThinkTop pulse seat clean

The Alfa Laval ThinkTop pulse seat clean, included as part of the ThinkTop V50 and V70 series control units, is designed to reduce the amount of cleaning-in-place (CIP) liquid required to clean drain valves.

As the valve is not controlled by a programmable logic controller but instead by the product, the amount of CIP liquid required is reduced and the seat is able to open and close more quickly and ensure that the valve cleaning is complete.

Short pulses are the primary force of the valve cleaning process and activate the valve when shear forces peak. Each pulse is less than a second, which reduces the chance of pressure shocks in the system while also creating high turbulent flow as the liquid passes through the small gap between the valve house and seat, which results in the residuals being removed from drain valves.

The product is intended to be used with single-seat or butterfly valves and can be configured as a normally open or closed shutoff or changeover valve.
