Fixed Flow Regulator- FFR2 FFR60W13YSN

The FFR-2 Fixed Flow Regulator provides an economical means of maintaining constant flow by the selection of a predefined orifice size.

This FFR-2 is a precision built, heavy duty, Fixed Flow Regulator is used as a liquid flow control device for Liquid Recirculation Systems. The Regulator establishes and maintains a constant flow rate determined only by the selected orifice number and independent of initial pressure drop or changes in the inlet or outlet pressure. By proper orifice selection an appropriate Fixed Flow Regulator can be chosen to maintain constant liquid flow at any one of nine different levels. To select the proper orifice multiply the evaporator load by the recirculation rate desired and choose the orifice with the rating closest to the calculated rating. Choosing an orifice with a lower number will decrease the recirculation rate, one with a higher number will increase it. Two or more FFR-2 Regulators may be installed in parallel to obtain capacities greater than available from one. Solenoid valves, hand valves or strainers placed upstream of the FFR-2 Regulators must be properly sized to give a low pressure drop that will not cause flashing. The FFR regulators must have 100% subcooled liquid refrigerant at the inlet with no flash gas present in order to give proper liquid flow control.
