(cylinder) seat, end cap gasket or orifice gaskets.
Remove these only if replacement seats and gas-
kets are available.
6. To remove body seat and seat gasket, insert an
appropriate tool or a heavy gauge wire with a bent
hook on the end through the center hole in the
seat. Pull to dislodge seat. if seat will not dislodge
easily, remove piping from exhaust port and push
seat out with a thin rod through the exhaust port.
To remove end cap seat and gaskets, push seat
from end cap, using a thin, blunt rod inserted
through hole between cylinder port "A" and cylin-
der port "B". When the end cap is of the type using
metering devices, compressed air applied
through either pipe connection or small vent hole
in the end cap should force out the seat with the
gasket. If this fails, using the appropriate tool or
bent wire described above should dislodge the
seat with the seat gasket.
7. All parts are now accessible for cleaning or re-
placement.
VALVE REASSEMBLY
1. Lubricate end cap gasket, end cap (cylinder) seat
gasket, body seat gasket, bonnet gasket and ori-
fice gaskets (2) with Dow Corning
lubricant or an equivalent high--grade silicone
grease. Lubricate seating surface of end cap seat,
body seat, and disc sub--assemblies (including u--
cups) with lubricant supplied in kit.
2. Replace body seat gasket on body seat and install
seat with gasket side first into valve body.
3. Preassemble disc sub--assembly on disc spring
and install into sleeve. Install remaining disc sub--
assembly from the opposite end. The disc sub--
assemblies will snap onto the disc spring if
pushed evenly and twisted slightly.
4. Install the sleeve (with disc assemblies and disc
spring engaged) into the valve body and onto core
at the same time.
5. Install the end cap assembly consisting of end cap,
end cap gasket, end cap seat, seat gasket and ori-
fice gaskets (2). Install end cap screws (4) and
torque in a criss--cross manner to 110 ± 10 in.--lbs.
(12.4 ± 1.1Nm).
6. Move the core up and down to see that it is properly
engaged and there is no misalignment or binding
of parts.
7. Replace bonnet gasket, sleeve spring, core spring
and core spring guide.
8. Replace solenoid base sub--assembly and torque
to 175 ± 25 in.--lbs. (19.8 ± 2.8Nm).
9. Replace solenoid enclosure and retaining clip.
10. After maintenance is completed, operate valve a
few times to be sure of proper operation.
