Open & Closed Center Hydraulics EH Models
The 1320 hydraulic system can be set up for tractors with
Open or Closed Center Hydraulics.
Open Centre Hydraulics
Most tractors have a hydraulic system that gives a continuous
output which flows through the valve on the machine and
back to tank when no function is operating (Open center).
Note:
The TANCO AUTOWRAP EH Models are set-up for open
centre on leaving the factory.
Close Centre Hydraulics
Some tractors (John Deere) have a hydraulic system
that require the valve on the machine to allow no
flow when no function is operating (Closed Center).
The hydraulic valve can easily be configured
to operate in this way.
Simply push and twist the Manual
Override on the Master Valve. (See Fig. 6.1)
Open & Closed Center Hydraulics SM Model
As with the EH models, the 1310SM is set for open centre hydraulics leaving the factory.
To convert to closed centre a plug on the valve must be changed. This plug is located
on the valve just beside the outlet (T line) (See Fig 6.2). Remove the existing one and replace with
closed center plug (Part No. Z01-03-A580J).
If you are likely to change frequently between open and closed centered hydraulic
systems and special plug incorporating a tap can be ordered.
(Part No. 1008050- closed center tap plug). This is fitted in the same position on the valve.
Push & Twist to lock for Closed Centre
