Description
There are various hydraulic manifolds with different functions available which mount on the attachment multi connector.
Flow divider valve
This manifold reduces the auxiliary hydraulics oil flow from the loader to the attachment by 50 %. This means that the attachment movement speed is 50 % slower, which can be useful in situations where a slower speed is required, without reducing loader engine revs too much.
Product no.: A421684
Double check valve
The double check valve is a lock valve which prevents the movements of the attachment’s hydraulic cylinder, in both directions, when the attachment is not in operation. This can be useful for instance with the log grab when handling delicate objects like kerb stones etc. – the lock valve makes sure that the grab cannot open.
Product no.: A422968
The 2-way adjustable pressure relief valve
The pressure relief valve releases the excessive pressure which can be generated in the attachment if it is mishandled by e.g. pulling it too much with the loader. The opening pressure of the relief valve can be adjusted. It controls both the pressure from the loader to the attachment and the pressure in the attachment. In addition, there is a third, feed/tank line which is useful when the attachment is equipped with hydraulic cylinder(s).
Product no.: A422104
Pressure gauges
The hydraulic pressures in the attachment, in both lines, are easy to check with these two pressure gauges. They mount on the A422104 2-way adjustable pressure relief valve. A422104 is not included.
