Danfoss H1T 045 - Page 21

The 045/053 tandem also supplies charge pressure to the port X7 for auxiliary operation of devices such
as spring applied/pressure released brakes. The control cut off valve also shunts pressure away from port
X7.
The 060/068 tandem offers a separate brake release valve that operates independently of the CCO valve
allowing the controls to be activated before activating any auxiliary functions. When the 60/68 brake
valve is deactivated the X7 port shunts to case.
