Design 461 Anti-Coke Valve Body (FISHEBj
May 1981
Form 5170
INTRODUCTION Scope Of Manual This instruction manual provides installation, maintenance, and parts ordering information for the Design 461 anti-coke valve body. Information regarding actuators and other accessories can be found in separate instruction manuals. Description The Design 461 is a self-cleaning, increased-outlet, angle-style valve body. It is specifically designed to control the flow of erosive or sticky fluids while preventing particle build-up on internal valve parts. It is used in both throttling and on-off applications. Because of its venturi-type outlet, the Design 461 valve body is often chosen for applications where flashing is a problem. INSTALLATION WARNING To avoid personal injury or equipment damage caused by sudden release of pressure, install the valve assembly only where service conditions will not exceed the limits given on the appropriate nameplate. 1.
Before installing a Design 461 valve body, inspect it for any foreign material that may have collected during crating or shipping.
2.
Check that the pipelines other foreign material.

Lubricate the body stud bolts (key 7) with Never-Seez* lubricant or equivalent, and install the nuts (key 8) on the bolts. Tighten the nuts in a range from 350 to 400 foot-pounds (474 to 542 newton-meters) in a crisscross pattern to ensure a positive seal and even pressure on the bonnet.

Lapping
Seating
Surfaces
A certain amount of leakage should be expected with metal-to-metal seating in any valve body. If the leakage becomes excessive, however, the condition of the seating surfaces of the valve plug and seat ring can be improved by grinding. Large nicks should be machined out rather than ground out. Use a conunercial lapping compound or a mixture of 600-grit Carborundum and solidified vegetable oil. Apply the compound to the bottom of the valve plug, and apply white lead to the seat ring to prevent excessive tearing or cutting during lapping. The white lead should not be mixed with the grinding compound, but rather applied separately. The valve must be assembled to the extent that the valve plug and stem assembly (keys 3 and 10) and the seat ring (key 2) are in place and the bonnet (key 14) is bolted to the body (key 1). A simple handle can be made from a piece of strap iron locked to the valve plug stem with nuts. Rotate the handle alternately in each direction to lap the seats. After lapping, remove the bonnet, and clean the seating surfaces. Completely assemble as described in the Assembly part of the Haintenace section, and test the valve for shutoff. Repeat the lapping procedure if leakage is still excessive. PARTS ORDERING Whenever corresponding with the Fisher sales office or sales representative regarding Design 461 valve bodies, be sure to provide the serial number given on the nameplate of the unit. When ordering replacement parts, specify the 11-character part number given in the parts list. *Never-See2
