PILOT OPERATED CHECK VALVE
SERIES 11
OPERATING PRINCIPLEMOUNTING INTERFACE
— This is a pilot operated check valve (spring closing and
cone on edge seals) with a built-in flow control feature.
The mounting surface is according to the ISO 4401
standard.
— The CHM5 are always mounted under the ISO 4401-05
directional solenoid valves and can be assembled with all
other ISO 4401-05 valves.
— The pre-opening feature of the valve causes the
decompression of the cylinder chamber, leading to a
smooth motion.

3 - HYDRAULIC FLUIDS
Use mineral oil-based hydraulic fluids HL or HM type,
according to ISO 6743-4. For these fluids, use NBR
seals (code N). For fluids HFDR type (phosphate esters)
use FPM seals (code V).
For the use of other kinds of fluid such as HFA, HFB,
HFC, please consult our technical department.
Using fluids at temperatures higher than 80 °C causes a
faster degradation of the fluid and of the seals
characteristics. The fluid must be preserved in its
physical and chemical characteristics.
Series No. (the overall and mounting dimensions
remain unchanged from 10 to 19)
