Parts Ordering - Emerson Fisher 63EGLP Instruction Manual

1. Remove the pilots and pilot pipe nipples from the
valve body. Remove the body flange plug (key 27)
and the spring (key 9) and attached parts.
2. Remove the cap screws (key 3) and pry the body
flange (key 2) loose from the valve body (key 1).
3. Use the valve body as a holding fixture if desired.
Flip the body flange over and anchor it on the valve
body as shown in Figure 10, removing the pipe plug
(key 31) first if necessary.
4. To gain access to the port seal (key 12), upper seal
(key 15) or valve plug parts, unscrew the seat ring
(key 13) from the cage (key 11) and the cage from
the body flange (key 2). For leverage, a wrench
handle or similar tool may be inserted into the orifice
slots (Figure 10) and a strap wrench may be wrapped
around the cage or a soft bar may be inserted
through the windows of a standard cage. To remove
the piston ring (key 14) and/or plug O-ring (key 20),
remove the valve plug (key 16) from the body flange,
insert a screw-driver into the pre-cut fold over area of
the piston ring and unfold the piston ring.
Installing parts without lubrication or
overtightening parts may affect shutoff.
5. Replace and lightly lubricate the gasket (key 4),
cage O-ring (key 17), port seal (key 12) and upper
seal (key 15). Ensure that port and upper seals are
installed in their retaining slots with the grooved
sides facing out. Also lubricate any other surfaces
as necessary for ease of installation. For proper
operation, a Type 63EGLP/63EGLP-16 valve plug
must have pipe plugs (key 31) installed in all four
balancing ports.
When tightening threaded parts together,
use a method of tightening, backing off
and tighten again until the union is snug.
6. Remove and replace the plug O-ring (key 20) and
piston ring (key 14) onto the valve plug (key 16).
Insert the valve plug into the body flange (key 2),
install the cage (key 11) plus upper seal (key 15) and
cage O-ring (key 17) into the body flange and then
install the seat ring (key 13) plus port seal (key 12)
into the cage. Use the valve body as a holding fixture
during this step as shown in Figure 10 and insert a
wrench handle or similar tool into the orifice slots for
leverage when tightening the orifice and cage.

When installing the main valve Repair
Kit, align the body flange and valve body
side tappings.
7. Remove the upside-down body flange (key 2) if it
was anchored on the body. Lightly lubricate the cage
seating surfaces of the valve body web and the body
flange. Install the body flange on the body (key 1)
and secure it evenly with the cap screws or stud bolts
(key 3). With a Type 63EGLP main valve, reinstall
the 3-way valve and its pipe nipple and connect the
pilot tubing.

and body flange threads before final tightening of
the plug.
