Choosing the right valve size is critical to ensuring that your process can achieve full-scale flow under your range of expected process conditions. An properly sized valve will give your mass flow controller or pressure controller stable control throughout the entire flow range.
Your instrument will be equipped with one of the following valve types:
We will tune your flow or pressure controller at our factory to ensure optimal performance for your specific application. If you have given your expected inlet and outlet pressures to your applications engineer, we will use them first to select the right valve and orifice, and then to replicate your expected conditions for valve tuning. If your flow conditions change after installation in the field, you can adjust the PID tuning from the front panel of your device or over a serial connection to your computer.
