The APV/Waukesha Cherry Burrell D4 Series double-seat mix-proof valve incorporates a CU4plus control unit with fully integrated seat lift detection. Designed with completely internal sensors, the control unit detects all critical valve positions. The unit features a teach-in function; a high-resolution, integrated measuring system; and a toolkit that provides the ability to monitor valve parameters, including the number of open/close cycles, strokes, operating hours, feedback position trends and power status. The control unit is suitable for all D4 Series valve types and can be retrofitted to existing D4 installations.
