 Flow Control Valves
All-Teflon Constant Flow Valve for Liquids/Chemicals

This constant flow valve has been developed for control of water and chemical flows. It maintains liquid flows constant against fluctuations of both primary and secondary pressure.



  • Outstanding control of liquid flows at a constant rate
      A valve composed of high-precision components ensures smooth control of flows.
  • Not affected by pressure variations
      Flows are maintained at a constant rate against fluctuations of both primary and secondary pressures.
  • Non-metal material(PTFE) used for the wetted part
      This resin(PTFE) is perfect for a part apt to be easily damaged by metal ions.
  • Small flows from 100-500 ml/min controllable
      Minute flows are also controllable optionally.
  • Model 2600,all-Teflon type,is compatible with practically all chemicals thanks to the use of a Perfluoro O-ring.
      (There are some operating conditions to be met according to the type of chemical. Be sure to contact us for information before placing your purchase order.)
  • Bubblers(air bubble purge taps) provided in the upper/lower diaphragm chambers
      Air bubble purge at the initial flow setting stage of operation provides the most accurate possible control
  • Ultrapure water analyzers
  • Environmental instrumentation systems ; food/chemical industry equipment
  • Ultrapure water and chemical mixing systems
