Abstract
A multiple control valve system comprises the first and second multiple control valves. To the first multiple control valve an additional attachment valve is operatively connected in a manner that pressurized oil is supplied to the first multiple control valve and the attachment valve from a common oil pump independently through respective conduits. The second multiple control valve is connected to the attachment valve through a conduit to which a remote control valve is disposed thereby to change over flow direction changeover valves contained in the attachment valve and the second multiple control valve to simultaneously operate these valves.
