Feature | DANA Mobile valve DCV

Infact the project of each single valve and the choice of the better materials, machined with the highest tecnologies and under the strongest controls in each process, allow highest characteristics and numerous applications described in the following pages.

  1. all the casting are made in Shell-Moulding, in special graphite cast iron. This kind of cast iron is in higt resistance, and it allows to have, with the same external overall dimensions, bigger internal gallery, and lower pressure drops
  2. all spools are made in high resistance steel, nichel plated, radial balanced and with special notches in order to have a better sensibility
  3. all springs are made in high resistence steel. Pressure setting springs are pressed before testing
  4. max tolerance of spool housing is 2 micron
  5. internal leakage at 120 bar, 50° C and oil 30 cSt is beetwen 1 and 2 cm³/min, depending from the kind of spool and the kind of valve.
