The FLOW-CONTROL series, designed by Bronkhorst, offers precise control of constant flow rates in low flow gas and liquid applications.

The control valves do not require any electrical power source, since the desired flow rate is manually set via the needle valve. Any upstream or discharge pressure variations are automatically compensated by a built-in membrane operated valve to ensure a steady, constant flow.

A statement from Mass Flow ONLINE said the new range ensures “a pressure sensitivity smaller than 0,5-1% Rd/bar.”

The manual operated, pressure compensated control valve series is available in four different models to control flow capacities in a range from 0.02 ln/min up to 50 ln/min (N2-equivalent) and 3 up to 1800 ml/min for water. While process connections are optionally available, the in-line valve assemblies are equipped with G 1/4” BSPP female in- and outlet ports.
