Variable Primary Pressure Flow Controller 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
• 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 level of secondary pressure (outlet pressure).
• 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.
• Physical and chemical appliances
• Control of the second-stage operation of pumps
• Various instruments for analysis
• Environmental instrumentation systems
• IN side filter joint Model 2300
• Connection joint
♦You may specify the fluid,pressure and flow rate of your equipment for our selection of the type that most suits your requirements.Use the values on Table of Rated Flow Ranges for reference purposes only.
♦At least an inlet/outlet pressure difference of 0.07 MPa is required.
