Converting single to double acting

[Fraserb]

Right folks have a mate with a mini digger and he's wanting to fit a tilting grading bucket to it, the issue is it has no service piped to the front but it does have pipework for a hammer so was wondering if its possible to plumb something up. Was wondering if it was possible to have a valve so when you press the pedal for the hammer it tilts one way then if you press a button on the joystick and press the pedal it would tilt the other way. Is there such a valve available?. thanks in advance

Not sure what machine it is but all the excavators I have had that are piped for hammer are both single and double acting, there's usually a butterfly valve somewhere around the valve block that changes it over.

Its a JCB, not sure what model, will find out though.

As said most machines will have a valve tucked away under the floor.normally a quarter turn valve.i got a breaker circuit on my volvo mini that can be used for double acting services even though the flow and return pipes are different sizes .get ont to ceforum.co.uk and ask away

An electric third slice of any front loader should do your job. Hit the pedal ram works one way, press the button and the pedal ram works the other? Does that sound right for what you want? Obviously if you need big flow you will need big valves.
Small pipe = pressure
Large pipe = return to tank

This one is 24Volt but just an example Click
Click the technical details on the page for a PDF on the valve

Edit:
Would it not be better to use the service going to the bucket and he wouldn't have to use the pedal at all? Just hit the button and keep hold of the joystick? Whats the button on the joystick used for at the minute?

Yeah what you describe is what I was thinking, i thought about a loader valve but i thought they wouldnt work as they are all ready double acting,

If it isnt a double acting hammer line as desribed above youre idea of using the bucket service would work, the button is for the horn at the moment.
