CORA Valve Recommended Maintenance Guidelines
Dear Valued CORA Ultra-Sanitary Butterfly Valve Customer,
To maintain proper operation of your CORA Ultra-Sanitary Butterfly Valves, we recommend that you have a few wear parts stored in your inventory for installation when needed.
The two main components within the CORA valves that we recommend you keep in stock are:
- Main Body Compression Seal
(item #1 on the sketch below)
- PTFE Shaft Bushings
(item #4 on the sketch below)
