Abstract
The invention relates to a valve arrangement for supply steam and cooling water under pressure alternately to a compression moulding tool, via respective inlet valves. Upstream of the inlet valve cooling water taken from the cooling-water circuit is passed to piston arrangements, which act upon the inlet valves, and is used both as a working medium for the piston arrangements and as a cooling agent therefor.
