New control unit for hygienic valve

08 July 2019

SPX FLOW has introduced a new control unit for its next generation APV/Waukesha Cherry BurrellD4 Series double seat mix proof valve. With fully integrated seat lift detection, the CU4plus, combined with the D4 Series hygienic valve is said to offer a sophisticated and reliable valve solution.

The CU4plus control unit features internal sensors to detect all critical valve positions, so the electronics are secure from damage during handling and washdown. 

For rapid commissioning, the unit incorporates a ‘Teach-in’ function, which enables reliable set-up of valve position and feedback with the push of just one button
Based on proven CU4 Series technology, the new control unit features a chemically resistant construction with ultra-bright LEDs for clear indication of valve position, power and solenoid activation. 
The new control unit utilises AS-i bus protocol and is suitable for all D4 Series valve types. It can also be retrofitted to existing D4 installations. SPX FLOW additionally offers a straightforward upgrade insert to change from the previous generation DA3+ to DA4 Series technology, which can now also incorporate the CU4plus control top.
