0,3 N•m). The placement of these screws should be such
that they give desired orientation of the housing later in
reassembly. Before completing reassembly, it is advisable to
apply pressure to the port which leads to the body chamber
and check for leakage around the flange seal. If the valve
has a sleeve port, the port at the top of the sleeve assembly
must be capped to make this test.
Leakage can be noted by applying a water and soap solution
to the joint and watching it for air bubbles. Once the housing
plate is secure, the yoke and coil may be pushed over the
sleeve assembly with a slight twisting motion. Replace the
housing with two screws. Tighten the screws to 18 ± 3 in/lbs
(2 ± 0,3 N•m). Repeat internal leakage check.
