Fine adjusting the valves in a dual valve assembly using flow control

One customer needed to match the flow rate through two valves in a dual valve assembly. They needed to be able to adjust one valve seat while and the other is off, and vice versa.

Process requirements

  • Measure pressure at both valve seats so that simultaneous adjustments can be made to match the flow rates
  • 0 to 70 SLPM of air at ~8.7 PSIG

Solution

Two MCP-100SLPM-D/CLP mass flow controllers connected by one BB9 multi-drop connection box for communication and power between a computer and both devices.
