Liquid Flow Control Valves

Bronkhorst® mass flow meters for liquids can be connected to a control valve to form a closed control loop. The standard direct acting valve, model C2I, is normally closed, has a pressure capability of 100 bar (1500 psi) and a purge connection for easy elimination of air or gas.
For liquid flow applications with higher flow rates and pressure rating up to 100 bar, Bronkhorst designed the control valve model C5I, however this control valve may also be used for gas flow applications.
C2I and C5I control valves are directly operated by a magnetic coil with IP65 (weatherproof) housing and are closed when de-energized (Normally Closed). Depending on flow rate and fluid the liquid flow control valves allows a pressure drop of max. 5 to 40 bar (d).
