Mass Flow ONLINE FLOW-CONTROL series pressure-compensated control valves

Mass Flow ONLINE has released the FLOW-CONTROL series, designed by Bronkhorst for 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. With their thought-out design and construction, the valve models are designed to ensure a pressure sensitivity smaller than 0.5–1% Rd/bar.

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