FLOW CONTROLLER (MANUAL [MECHANICAL] MASS) - MODEL VCD 1000 -- VCD-SVS-35

Model VCD 1000 Variable Constant Differential Flow Controller is designed to control low gas flows at constant mass flow rates regardless of downstream pressure fluctuations. The Model VCD 1000 design yields extremely linear flow output in relation to adjusting stem rotation while offering bubble-tight shut-off. - Model VCD 1000 Variable Constant Differential Flow Controller is designed to control low gas flows at constant mass flow rates regardless of downstream pressure fluctuations.
