FAQ
Should I replace valve balls and seats together?
Yes — they wear as a pair. Replacing only one side accelerates wear on the other.
What material valve ball for abrasive slurries?
PTFE balls for chemical service; for abrasive media consider SS or ceramic check balls.
Why does my pump lose prime?
Usually worn valve balls/seats — check and replace the pair first.
