Variable Primary Pressure Flow Controller(Not subject to supply pressure variations)
MODEL 2204 SERIES
 

Model 2204 Variable Primary Pressure Flow Controller is a control valve that always keeps flows at a constant rate under a given constant level of secondary pressure (outlet pressure) even when the primary pressure (inlet pressure) fluctuates. The built-in precision needle valve accurately controls flows to the set flow rate,including ultra-minute flows.

 

 
Features
  • Stable flow control
    A non-rotary needle valve composed of high-precision components ensures smooth control of even ultra-minute flows.
  • Not subject to supply pressure fluctuations
    Flows are protected from being affected by primary pressure(supply pressure) fluctuations,under a given constant
  • Cleanliness ensured
    All the high-precision components are super-cleaned before assembly so that the product can be safely used even on high-sensitivity instruments for analysis for which cleanliness is essential.
 
Applications
  • Physical and chemical appliances
  • Control of the second-stage operation of pumps
  • Various instruments for analysis
  • Environmental instrumentation systems
