Compatible Systems for Graco 115830 Compression Spring

The Graco 115830 Compression Spring is a factory‑specified coil spring used inside internal valve or piston assemblies of Graco sprayers and pump systems — providing the needed compressive force to actuate valves or return pistons reliably after each cycle.

Graco spray‑pumps / coating machines where 115830 is listed as “SPRING, COMPRESSION” in parts‑diagram (valve or piston return spring) :contentReference[oaicite:5]{index=5}
Fluid‑handling / pressure‑pump assemblies needing a reliable spring to maintain valve or piston function under repeated cycles of operation
Maintenance or repair jobs — when original spring is worn out or damaged, 115830 can be used as OEM replacement to restore correct functioning of valves/pistons

Frequently Asked Questions

A compression spring resists compressive forces — when valve or piston moves due to pressure or manual actuation, spring compresses, and once force reduces, spring pushes back, helping valve/piston return or stay closed/open as required. :contentReference[oaicite:6]{index=6}

Because spring’s stiffness (spring‑rate), length and material determine how accurately valve/piston moves and seals — if spring wrong ho, valve may leak, piston return na kare, ya pressure cycles disturbed ho. OEM spring ensures correct spec and reliable operation.
