Bonnet - Emerson Fisher Multiport Flow Selector Instruction Manual

Instruction Manual

3. Install the back up plate (key 16) against the shoulder in the plug (key 2).
4. Install the O-ring (key 14) onto the seal carrier (key 13). Install the seal assembly into the plug. Hand force should
only be required for proper installation.
5. Install the correct number of wave springs (key 11) followed by the scraper (key 10) into the plug over the seal
assembly. For NPS 2x4 constructions, install two wave springs and for NPS 3x6, 4x8, 4x10, and 6x16 constructions,
install one wave spring. Ensure the scraper fits freely into the plug. Check by pushing the scraper into the plug using
both hands then letting go to see if it returns to its original position.
6. Lower the plug (key 2) into the body ensuring that the seal insert (key 12) and scraper (key 10) clear the bore of the
body (key 1). When installed, the plug rests on top of the plug bushing (key 9).
7. Lubricate the tapered bearing cone and rollers (key 3) using a high temperature silicone grease (key 39) and install
onto the plug.
Bonnet (Key 19)
1. Lubricate and press fit the bearing cup (key 3) into the bonnet using a high temperature silicone grease (key 39).
Lubricate the bearing cup and press fit it into the bonnet.
2. Install the backup ring (key 6), O-ring (key 5), and rod seal (key 4) into the bonnet bore. Rod seal is not required for
NPS 2x4 or 3x6 CL300, 600, and 900 rated valves.
3. Install the bonnet O-ring (key 20) into the groove of the bonnet. For NPS 4x8, 4x10, and 6x16 constructions, install
the backup ring above this O-ring.
4. Install the wiper seal (key 24), lube fitting (key 28), and vent plug (key 27). For NPS 4x10 and 6x16 constructions,
install the wiper seal on an external wiper retainer (key 24) with two extra O-rings (key 25 and 26).
5. Using two eye bolts threaded into the jack screw holes found on the bonnet, slowly lower the bonnet onto the
body. Be careful not to damage any soft parts when feeding the plug through the bonnet. The bonnet has been
properly positioned onto the body when the following has been achieved:
D The bolt holes in the bonnet have been aligned with the stud holes in the body.
D The centerline of the bonnet vent port has been aligned with the centerline of the group outlet of the body.
Excessive force should not be required to properly seat the bonnet onto the body. For NPS 2x4, 3x6, and 4x8
constructions, use hoist rings or eye bolts with 1/2 UNC threads. For NPS 3x6 CL1500, 4x10, and 6x16
constructions, use hoist rings or eye bolts with 3/4 UNC threads.
6. Lubricate studs (key 31) with an anti-seize lubricant (key 40) and thread into valve body (key 1). Place the
appropriate number of lifting lugs (key 33) over these studs. The placement of these lifting lugs should be equally
spaced with one being located directly above the group outlet. The placement of these lifting lugs is as follows:
D For NPS 2x4, 3x6, 4x8, and 4x10 constructions, place two lifting lugs equally spaced with one being located
directly above the group outlet port.
D For NPS 6x16 CL300, 600, and 900 constructions, place three lifting lugs equally spaced with two of them
straddling the group outlet port.
D For NPS 6x16 CL1500 and 2500 constructions, place four lifting lugs equally spaced with two of them straddling
the group outlet port.
7. Lubricate the threads and the bottom surface of the nuts (key 32) with an anti-seize lubricant (key 40) paste prior to
threading them on to the studs (key 31). Once all nuts have been threaded hand tight, tighten two nuts spaced
180-degrees apart to the recommended torque values per table 6. Rotate the plug (key 2) one complete revolution
to ensure that it rotates with minimal resistance. If the plug rotates smoothly, then proceed to tighten the
remaining nuts using an appropriate tightening pattern.
8. Using the lube fitting (key 28), fill the bearing bore with grease.
