NI-029 Rev. 7 ⇒ September 2016
C- Assembling DCX3 automatic valves
Check that the seal-bearing surface inside the body ( 1 ) is clean. Check the position of the seal ( 3 ) on
the actuator ( 5 ). Put the valve in the “open” position. With an N.C. configuration, supply the actuator
( 5 ) with air and insert the shut-off assembly ( 2-3-4-5-6-8-9-10 ) in the body making sure the seals are
not damaged around the ends of the parts. Refit the clamp« 7 ». When using for the first time, check the
bottom connection and top connection(s) for leaks.
NOTE:
− We recommend the use of a medium threadlocker to lock the piston during its reassembly to the
automatic actuator.
− During sawing operations, prevent chips or filings from entering the pipes and rinse the pipes
thoroughly with the valve open to avoid damaging the seals when the valve is put into service.

STORAGE
We recommend that our valves are stored away from site pollution (abrasive dust, shocks, acid or
chlorinated products, U.V., etc.) for as long as possible and are assembled, where possible, to avoid
mixing up of components.
