Operating Parameter Guidelines: - Max. Pressure: 5,000 psi - Max. Vacuum: 30 Hg
ILS3211200 REV L
- Max. RPM under vacuum: contact factory - Max. RPM under pressure: see table on page I-3 - Operating Temperature Range with slip ring: 0° - 176° F - Max Operating Temperature Range without slip ring 0°- 220° F - Air may be run in any available passage
For Proper sealing, mating surface should be flat to 0.003 in. with a maximum 32 µ in. R a surface finish.
- Rotating unions are not intended to be a structural member. It is recommended that the anti-rotate arm should attach to the stationary part of the union and should be fully supported by external framework. Load on the union should be minimized. Please contact Vektek for technical assistance. - Separate air and fluid with extra passage between them.
