For Proper sealing, mating surface must be flat within 0.003 in. with a maximum 32 µ in. R a surface finish.
Operating Parameter Guidelines :
- Operating Temperature Range: 40-160° F. - Max. RPM see table on page I-1. - Max Torque see table. - Torque requirements may vary depending on port configuration and pressure run through ports. Testing of your specific application may be required. - Air may be run in any available passage. - 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. - Installation Instructions Available, Request IS3207. - Recommended feed hole Ø.250 - Ø.125.
