Filton® Rotary P.B. Union
(Sizes 1/2" to 1")
Installation Procedures
- A suitable run-in period before fitting is recommended. Rotate the P.B. at 300 r.p.m. for 15 minutes.
- Add system liquid if seals squeak.
- A torque arrestor may be fitted, but this must not restrict the rotary union.
- Ensure that the spindle thread is RH or LH to suit the direction of rotation of the machine shaft.
- If the machine shaft reverses direction of rotation, securely lock the spindle or (preferably) use a flanged connection.
- DO NOT fix valves etc. directly on to the rotary union.
- DO NOT connect with rigid pipe.
- DO NOT clamp the rotary union.
