The C500 diffuser is the latest addition to our family of high-pressure fluid control devices. It was developed to complement our highly popular B400 orifice so that when placed in series, they would mitigate the damage that can be caused by the rapid reduction in the pressure of a flowing hot condensate stream.

For example, two of the most difficult flow control problems in a power plant are the control of the Boiler Feed Pump recirculation and warm-up systems. Another example is the boiler blowdown system.

Because of the high-pressure drops involved with these high temperature liquid streams, the fluid flashes across the system control valve. This erodes both the control valve and the downstream piping. In addition the resulting pounding as the fluid implodes causes unacceptable noise and vibration of the piping. In some cases, the control valve, the downstream piping and the hangers must be replaced in a matter of months.

C.U. Services now offers a solution to these problems. It involves two stages: The flow is first limited with a B400 orifice. The energy is then diffused in the C500 diffuser. This greatly reduces or eliminates the flashing and implosion damage. The C500 and the B400 are fabricated from forged bar stock ASME-SA479-316SS.
