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
1.Stable flow control
A non-rotary needle valve composed of high-precision components ensures smooth control of even ultra-minute flows.
A non-rotary needle valve composed of high-precision components ensures smooth control of even ultra-minute flows.
2.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).
3.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
1.Physical and chemical
appliances
2.Control of the second-stage operation of pumps
3.Various instruments for analysis
4.Environmental instrumentation systems
