Siemens Differential Pressure Feedwater Control (DPFC) is an integrated system based on a highly accurate Differential Pressure (DP) transducer(s) coupled to a RWF40 universal controller. The RWF40 controls the Feedwater valve actuator directly (electro-hydraulic actuator), or through an I to P converter (Pneumatic valve actuator). Many different actuators and feedwater valves are offered to accommodate different feedwater pressures and flows.
The DPFC may be used on Firetube and Watertube Boilers, as well as Deaerators. It can be set up as a single or a dual element level control, depending upon which sensors are connected. ModBus communications are also available via the RWF40, allowing the DPFC to interface with a building management system or a HMI (touch screen). These features make the DPFC extremely flexible, and ideally suited for use on most steam boilers and Deareators.
