Kofloc Model 2203 Series | Variable Secondary Pressure Flow Controller
A flow controller is a differential pressure regulator designedto control minute gas flows with precision and keepa certain constant flow rate.
Kofloc valve Model 2203 Variable SecondaryPressure Flow Controller is a control valve that keepsmass flows at a constant rate under a given constant levelof supply pressure even when the load pressure on thesecondary side (outlet side) fluctuates, and its constructionis designed so that the performance of its precision controloverflows to the set flow rate is maintained by the incorporatedprecision needle valve without being affected bysuch 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.
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.
Environmental instrumentation systems
Gas mixing systems in various fields
Rated flow ranges : Gas: 10 ML/min–20 L/min
Control accuracy: Change in reading within 1.0% of the change in load pressure (Inlet-outlet pressure difference must be at least 0.05 MPa.)
A number of turns of regulating screw: Approx. 12 turns
