Veriflo Regulators


Veriflo 735 Series

735 Series Regulator -The 735 Series regulator offers a two stage, tied diaphragm design to provide a constant outlet pressure regardless of inlet pressure fluctuations - excellent for high pressure/low flow conditions. Configure a 735 regulator and obtain a quote!

 Veriflo 959 Series

959 Series Regulator - The 959 Series is a single stage tied diaphragm regulator that provides positive shut off if a leak across the seat occurs.  The unique compression member loading eliminates threads in the wetted area, thus reducing particle entrapment.
