PLAST-O-MATIC FC Constant Flow Valves

Descriptions of PLAST-O-MATIC FC

These flow controls are designed for liquids similar in viscosity to water. All applications should be tested for flow characteristics and chemical compatibility 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).

FEATURES/BENEFITS:
• Maintain constant flow with inlet pressure fluctuation from 15 to 120 PSI (1 Bar to 8 Bars) with ±15% accuracy. Test equipment is NIST certified.
• For corrosive and ultra-pure liquid applications.
• No metals in contact with the liquid.
• Standard flow ranges from ¼ GPM to 8 GPM; 9 to 120 GPM by special order.
• Automatic in operation – no adjustments.

APPLICATION:
Recommended whenever flow rate must be maintained regardless of unplanned or fluctuating demand elsewhere: Install Series FC prior to each point of use to eliminate surges and sudden drops in flow.

Technical specifications of PLAST-O-MATIC FC

MATERIALS OF CONSTRUCTION:
The standard Series FC flow controls are constructed of TYPE 1, GRADE 1 PVC (Polyvinyl Chloride) with diaphragms of EPDM. Stainless steel fasteners are non-wetted. Bodies are also available in virgin polypropylene, PTFE and Kynar PVDF.

OPERATION AND INSTALLATION:
The Series FC flow controls are used to maintain a constant predetermined 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. Standard flow ranges are from ¼ GPM to 8 GPM with 9 – 120 GPM by special order (.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.
