The FB5CPM (inlet) and FB6CPM (outlet) are air-loaded sanitary, constant pressure modulating valves (CPM) designed to allow the user to change set points remotely via a cabinet or panel mounted air regulator, or through a distributed control system or PLC, using an I-P transducer. It is a suitable choice for automating and maintaining constant pressure set points on the inlet side of the valve for control operations, whether they are process set points or points to fully open the valve for rinse, CIP or SIP. The valve is preferred in HTST/UHT pasteurization, after heat exchangers, separator equipment and bottling lines.
