Flow increments: 1/4, 1/2, 3/4, 1, 1½, and 2 GPM (1.0, 1.9, 2.8, 3.8, 5.7, and 7.6 l/m) flow rates, then in 1 GPM (3.8 l/m) increments from 3 to 120 GPM (22.7 to 454.2 l/m).
These flow controls are designed for liquids similar in viscosity to water. All applications should be tested for flow characteristics and chemical compatability to insure desired results. Swelling of the diaphragms in certain liquids will result in loss of flow rate accuracy. An in-line strainer or filter should be installed before the flow control when suspended solids are present, and for all applications below 1.0 GPM (3.8 LPM).
The rated output of Series FC flow controls will vary ±15 percent with EPDM assemblies.
The standard Series "FC" flow controls are constructed of TYPE 1, GRADE 1 PVC (Polyvinyl Chloride) with diaphragms of EPDM. Stainless steel fasteners are standard. Bodies are also available in virgin polypropylene, PTFE, and Kynar®. Consult factory.
The Series "FC" flow controls are used to maintain a constant pre-determined flow in a system. They must be installed in the correct flow direction (indicated by label) to work properly. They utilize a diaphragm which changes shape with inlet pressure changes, thus maintaining a constant flow rate. They are normally used to replace more costly flow control devices. Standard flow ranges are from 1/4 GPM to 120 GPM (.95 LPM to 454 LPM). The minimum pressure drop needed across the flow control is 15 PSI (1 Bar) in order to get the desired flow.
The Series "FC" flow controls can operate from 40 °F - 140°F (5°C-60°C) with PVC bodies and EPDM diaphragms. With optional polypropylene, PTFE, or Kynar bodies they can operate from 40°F- 180°F (5°C-82°C). The Series "FC" flow controls must have at least 15 PSI (1 Bar) pressure drop across the control in order to deliver the rated flow. Maximum pressure is 120 PSI.

FC 050 EP - 001-1/2 - PV See Table Diaphragm Flow Rate(See Table) Body Material EP-EPDM PV-PVC TF-PTFE PP-Polypro PF-PVDF/Kynar Please note that the GPM part numbers are as follows: 1/4 Gallon: 000-1/4 1/2 Gallon: 000-1/2 3/4 Gallon: 000-3/4 1 Gallon: 001-000 1 1/2 Gallon: 001-1/2 2 Gallon: 002-000 Above 2 GPM, fractional rates are not available, so only three digits are needed in the part number. For instance, 45 GPM would be 045. In other words, a 2" FC in PVC with EPDM delivering 45 GPM would be: FC200EP-045-PV
