Duplomatic CBM3 | flow control valve

Function and application

The CBM3 is a modular, non‑compensated flow control valve based on the hydraulic Graetz‑bridge principle . It ensures a constant unidirectional flow at outlet port A , while port B acts as the return path, regardless of whether the main supply is fed from A1 or B1. This behaviour makes it ideal for circuits in which the flow direction may reverse during the operating cycle. The mounting surface of the CBM3 features a bolt‑hole pattern and port layout compliant with the ISO 4401‑03 standard , allowing straightforward integration into standardised valve stacks. The CBM3 is typically installed beneath compensated flow control valves , such as the Duplomatic RPC1 and RPCED1 . In this configuration, it operates as a rectifier plate, ensuring a stable and constant flow direction towards the compensated valve, even in the presence of reverse flow caused by actuator movement or variations in the duty cycle.

Selection and RFQ

For an RFQ, provide SUMY with series CBM3, catalogue 65 220, required quantity and operating conditions. Confirm the required size/interface (ISO 4401-03) and configuration before ordering.
