Gas Rated Visco Jet® Multi-Orifice Restrictor

This gas-tested, multi-orifice flow restrictor, incorporates slots and spin chambers to form a complex fluid passage. This provides a greater minimum passage for a given restriction and is better suited to handle much higher levels of contamination. Manufactured entirely from stainless steel, this flow restrictor is suitable for working pressure differentials up to 5000 psi. It is 100% bidirectionally flow tested on nitrogen at a ± 5% flow tolerance and is precision cleaned to the IEST-STD-CC1246 level 100 standard. This restrictor is available in a wide range of Lohm rates.
