Valve Springs |
|
|
 QualCast springs are made from super clean carbon steel wire (non-metallic particles
can reduce steel strength). We also use chrome, chrome vanadium, or AS-25, depending
on the application.
Engineered Features
Single Spring Design - ground flat on top and bottom for straightness and shot-peaned
for heat-related fatigue resistance.
Spring With Damper - A flat ribbon damper on
the inside diameter of the spring reduces spring "bounce" and "surge". We identify
springs with dampers by the part number suffix "-D".
Double Spring Design - Many
heavy duty applications have an inner and outer spring; the double springs give
additional strength pressure to seat the valve.
