Description
The Bedford 23-1646 is a compatible replacement for Graco parts 157630 and 157-630 — the spring used in Graco spray equipment. This spring keeps its valve components loaded against their seats, so the valve closes crisply on every cycle instead of drifting or chattering. Spring steel fatigues gradually — tension loss shows up as inconsistent operation long before the spring visibly fails. Compatible with Graco 1:1 Fast-Ball and Standard Air Motor.
Common reasons for replacement:
- Inconsistent valve action as spring tension fades
- Ball or poppet chatter from a weakened spring
- Collapsed or kinked coils found during teardown
- Renewed as cheap insurance during any valve rebuild
Manufactured to OEM-equivalent dimensions for proper fit and performance.
