Industrial Flow Restrictors

Porous metal flow restrictors are used in applications that require anti-clogging or laminar flow. The thousands of different flow plaths through the porous metal will prevent the restrictor from clogging if it large particle makes it into the gas stream, such as with a flow orifice. This thousand pore structure also ensures laminar flow in even the most intense conditions and eliminates turbulent flow on the outlet. Restrictors are available in a wide variety of alloys and hardware configurations to fit into your process.

Product Specs

Compatible Flow Rates

Mott can tune restrictors to a virtually infinite number of flow rates. Consult with a Mott representative to procure a flow restrictor that’s right for your process conditions.

Flow Accuracy

Mott restrictors are typically +/- 7.5% of the specified flow rate. Ultra-high accuracy restrictors can be manufactured upon request with accuracies down to 1%. For ultra-low flow rates, broader accuracy ranges may be required.
