counterclockwise and remove the pilot assembly from
the adaptor.

3. Install the new pilot assembly. (At this point the flange is
still securely bolted to the valve body.) Again place a wrench
on the bottom connection of the pilot valve. Turn clockwise
until the pilot assembly is firmly in place. Do not attempt
to align the three pilot valve connections at this time.
4. Remove the locknut or cap screws and replace the gasket
under the adaptor. Two gaskets are supplied with each
pilot assembly kit. The correct gasket for the (S)ORIT-12
and -15 is the tetraseal. The (S)ORIT-20 uses the compo-
sition gasket. See Figure 2 for actual dimensions of the
tetraseal and the gasket.
