8.8 Checking valves
Valve removal 1. Loosen all unions and hose lines at the cylinder heads.
2. Remove cylinder head nuts and remove the cylinder heads.
3. Take valves carefully out.
Checking the
lamellar valves
4. Check the valves.
If the reed (lamellar) valves are heavily carboned or dama-
ged, replace the complete valves.
Hinweis!
Reed (lamellar) valves, are those parts of a reciprocating com-
pressor that are subjected to the most stress. In order to achieve
the guaranteed maintenance intervals, these valves are high-
quality precision parts, specially matched to the individual com-
pression stages and their function carefully checked before deli-
very. Repair by maintenance and operating personnel requires
specialist knowledge, which may not be readily available. In
such a case J.P. SAUER & SOHN can offer a valve replacement
service; please contact the Sauer service department.
Note!
Install all valves with new gaskets and seals. Do not reuse the
used old seals under any circumstances. Doing so leads to
leakage within a short time.
Use only genuine Sauer spare parts. They are precision parts,
designed, tested with special material characteristics for use in
Sauer compressors. Installation of other gaskets may lead to
leakage and may cause substantial damage to the compressor.
Note!
Reed (lamellar) valves require very little maintenance and
function even when in the presence of small quantities of dirt in
contrast to plate valves. Normally the plates have the same
service life as the valve body which, due to its geometry, cannot
be re-faced or lapped. Therefore, replacement of individual parts
is not recommended.
Should a plate be broken prematurely (e.g. from foreign objects),
please contact Sauer service.
