High pressure flow restrictors for critical applications

Lee Products has added a robust, high pressure option to its range of JEVA restrictors that is rated to handle system pressures up to 5,000psi.

The new Lee 5k JEVA offers exceptional corrosion resistance and performance in demanding, harsh situations and critical duties, including those encountered in aviation and aerospace applications.

Constructed entirely from 316L stainless steel and weighing just 1.8g, the 5K JEVA restrictor utilises technology which is similar to Lee’s traditional Visco Jet restrictor in that it offers a reasonable degree of viscosity compensation without the use of any moving parts.

In addition, the metering element includes many orifices in series to lower fluid velocities and thus reduce the possibility of cavitation.

This multi-orifice restrictor also offers up to a 280 percent increase in minimum passage size over a comparable single orifice restrictor and therefore a higher tolerance to contamination. It is available in 93 different Lohm rates, ranging from 3520 up to 313,000 and is protected by two integral safety screens for bi-directional flow capability.
