4. Service valve plate kits include:
(1) valve plate assembly, (2) suction reed valves, (3) cylinder head gaskets (side, center and
suction gas unloading), (1) valve plate gasket; and for 06D compressors there are (2) suction
valve position springs.
5. All new high efficiency 06DM, 06DA, and 06CC (16 to 37 Cfm) compressors have flat top
pistons. All new high efficiency 06DR and 06ER compressors have one step contoured pistons.
All new high efficiency 06EM, 06EA, and 06CC (50 to 99 Cfm) compressors have two-step
contoured pistons.
6. The outer edges of the valve plates have “ears” that are visible when installed on the
compressor. All new high efficiency valve plates have one elongated “ear” versus one or two
rounded “ears” on the older standard efficiency valve plates. Note the valve plate supplied in
package 06ER660017 for environmental chambers has two rounded ears.
3.30 — Muffler Recommendations
Mufflers can reduce discharge gas pulsation and effec-
tively eliminate vibration problems downstream. They
should be placed as close to the compressor as possible
to maximize efficiency and minimize vibration. Mufflers
should be:
• used on all 06E 66 and 99 Cfm compressor models.
• used on all 06E compressors with capacity control.
• considered for use with all 06D 37 and 41 Cfm
compressor models.
• considered for use with all 06D 6-cylinder compres-
sors with capacity control
Mufflers can be mounted horizontally or vertically.
