Valve Guides
JEETAI valve guides are professionally supplied
to vavious engines applicable on vehicles, vessels and construction machines. The
requirements of modern emission control engines present unique challenges to
cylinder head rebuilder. Almost all new OEM engine designs incorporate positive
valve stem seals and chrome plated valves to reduce exhaust emissions. The fact
together with higher operating temperatures has made good guide lubrication a
prerequisite of a good valve job. So JEETAI valve guides are primarily produced
in materials of cast iron with higher graphite content, iron based powder or
copper alloy, which improves the performances of self-lubrication and wear resistance.
The following drawings are NOT to scale, but
only general outside shapes of valve guides we produce. They also don’t mean
all we produced listed.
