Constant Flow Valves
Series FCMaintain constant flow to 15% accuracy with inlet pressure changes from 15 to 120 PSI (1 bar to 8 bar). Valves are pre-set with NIST certified test equipment. Series FC is tamper-proof.
Available in pipe sizes 1/4″ through 1″, with standard flow ranges from 1/4 GPM to 9 GPM. Larger pipe sizes with flow rates up to 120 GPM available as Specialty Custom items; consult factory.



Air Operated Filling/Metering Pumps
Series VPAmetering pumps are air-operated, self-priming, positive displacement type pumps designed to meter precise quantities of liquids, accurate to 1/2 of 1%. The four sizes of pumps available have a single stroke maximum delivery capacity of 7, 10, 32 or 128 liquid ounces, adjustable to deliver smaller portions. Series VPA is aSpecialty Customproduct; please contact factory for price and availability. Minimums may apply.

Pulsation Dampeners/Surge Suppressors
Series PDSProvides six important functions:
•Pulsation Dampener smooths pump flow
•Surge Suppressor absorbs shocks and vibrations
•Water Hammer Arrestor eliminates dangerous pressure spikes caused by quick closing valves
•Inlet Stabilizer enhances pump performance and longevity
•Accumulator releases stored fluid during unwanted pressure drops
•Expansion Tank protects system from thermal volume increases
…available with threaded connections in three capacity sizes and a variety of thermoplastic materials. Please see PDF for more information.




Calibration Columns
Calibration Columnsverify pump flow rates, chemical dosing, or chemical feed systems with higher accuracy than competitive models. Constructed of UV Resistant PVC and designed for precise, efficient testing with a variety of installation options. All sizes/models carry a lifetime guarantee against yellowing or other UV damage.
