Constant Flow Valves

Series FC valves maintain constant flow with inlet pressure changes from 15 to 120 psi (1 bar to 8 bar). Available in pipe sizes 1/4" through 1", with standard flow ranges from 1/4 gpm to 8 gpm. Larger sizes (up to 3" FNPT) and higher flow rates (up to 120 gpm) are available by special order; contact us for a quote. Valves are pre-set and tamper-proof.
