Variable Secondary Pressure Flow Controller MODEL 2203 SERIES

Variable Secondary Pressure Flow Controller

A flow controller is a differential pressure regulator designed
to control minute gas flows with precision and keep
a certain constant flow rate. Model 2203 Variable Secondary
Pressure Flow Controller is a control valve that keeps
mass flows at a constant rate under a given constant level
of supply pressure even when the load pressure on the
secondary side (outlet side) fluctuates, and its construction
is designed so that the performance of its precision control
over flows to the set flow rate is maintained by the incorporated
precision needle valve without being affected by
such fluctuations.



• Stable flow control
A non-rotary needle valve composed of high-precision components ensures smooth control of minute flows.
• Not subject to load pressure fluctuations
The incorporated precision needle valve protects flows from being affected by secondary or outlet pressure fluctuations, so the product is a 'must-be' tool in the first stage of any flow control line.
• Cleanliness ensured
All the components are super-cleaned before assembly so that the product can be safely used even on instruments for analysis for which cleanliness is essential.


• Gas chromatographs
• Environmental instrumentation systems
• Gas mixing systems in various fields
