Porous metal flow restrictors provide permanent, reliable flow control in high purity applications without the high cost of mass flow controllers. These flow restrictors also eliminate the susceptibility to tampering and incorrect adjustment of needle valves, and the turbulence and clogging caused by calibrated precision flow orifices.
Our flow restrictor products can be calibrated to virtually any flow rate and any gas, accommodating upstream and downstream pressures from vacuum to 1500 psi.
