Take the valve "3", place the valve seal "4", add the spacer "5", place the valve seal "6", add the sleeve "7".
Place the assembly onto the mechanism "15", taking care not to damage the seal and the segment "13", then screw and
tighten the valve using the flats on the valve (use thread locker), then (N.C. assembly, supply the mechanism "15", N.O.
assembly, cut off the air). Position the lower body "1" paying attention to the seal and tighten the nuts "9" on the dowel
pins "2". Then (N.C. assembly, turn off the air, N.O. assembly, supply the mechanism "15") and check the correct
centring of the valve by the lower track. When using for the first time, check for leaks of the lower section in the low
position, then of the upper section(s) and of the lantern in the high position.
N.B.:
− We recommend the use of a medium thread locker glue to secure the valve when reassembling on the mechanism.
− During sawing operations, please avoid the introduction of chips or filings inside the pipes and rinse the pipes with
a generous amount of water to avoid damage to the seals during commissioning.
