Technical Information Series CM
General Description
Series CM check valves provide an integral, full ļ¬‚ow
check valve in the pressure 'P' port, 'A' port, 'B' port, or
the tank 'T' port of the directional valve. Reverse ļ¬‚ow is
blocked. The CM2 and CM3 sizes offer a combination
P&T check version.
Features
ā€¢
Valve bodies are manufactured from steel which provides
extra strength and durability for longer life. Internal hard-
ened steel components also provide longer life.
ā€¢
Positive shut-off is provided by a fully guided poppet and
allows full ļ¬‚ow in the unchecked position.
ā€¢
Parker CM sandwich style check valves can be used either
on the 'P', 'A', 'B', 'T' ports, or combinations.
ā€¢
Large internal ļ¬‚ow paths allow high ļ¬‚ow at low pressure
drop.
