Fisher FBT Valve with Piston ActuatorX1324-1 IntroductionScope of ManualThis instruction manual includes installation, maintenance, and parts information for Fisher FB valves . For informationon availability of complete assemblies and spare parts, contact your local Emerson sales office or Local BusinessPartner.

2 Refer to separate manuals for instructions covering the actuator and not install, operate, or maintain an FB Valve without being fully trained and qualified in Valve , actuator, andaccessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important tocarefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If youhave any questions about these instructions, contact your Emerson sales office or Local Business Partner valves , which include FBD and FBT (figure 1), are fabricated or cast angle valves that are custom built for specialapplications.

3 The basic construction, however, is similar in all the valves . For applications up to 232_C (450_F) or up to316_C (600_F) with the use of anti-extrusion rings, the seat ring is screwed to the free end of the cage assembly of theFBT ManualD100402X012FB ValveAugust 2018 Instruction ManualD100402X012FB ValveAugust 20182 Table 1.

The pressure or temperature limits in this manual and any applicable standard limitations should not be top of the cage assembly is clamped between the Valve flange and bonnet, permitting unrestricted movementduring thermal expansion and contraction (see figures 9 and 16).

5 A spring loaded seal ring provides a seal around theoutside of the seat ring. The top of the cage assembly is also clamped between the Valve flange and the bonnet forapplications above 232_C (450_F), leaving the cage assembly free to expand and contract. For these high temperatureapplications, however, the seat ring is separate from the cage assembly and is welded into the FBD Valve (see figure10). No seat ring seal ring is required. The cage assembly is free to expand and valves are available in CL150, 300, or 600 with flanged or butt weld ends.

6 Special constructions with a CL900rating, or with the inlet designed for a Valve class rating greater than the outlet, are available on an individual basis. Ifthe Valve has an inlet pressure rating greater than the outlet pressure rating, it is especially important to haveadequate overpressure protection downstream to protect against the possibility of full inlet pressure reaching thedownstream specifications for these valves are shown in table ServicesFor information on available courses for the Fisher FB Valve , as well as a variety of other products, contact: Emerson Automation SolutionsEducational Services - RegistrationPhone: 1-641-754-3771 or 1-800-338-8158E-mail.

7 ManualD100402X012FB ValveAugust 20183 Installation WARNINGTo avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valveassembly where service conditions could exceed the limits given in this manual or on the appropriate nameplates. Usepressure relieving devices as required by government or accepted industry codes and good engineering wear protective gloves, clothing, and eyewear when performing any installation operations to avoid with your process or safety engineer for any additional measures that must be taken to protect against installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in thisinstruction 2.

9 Because some body/trim material combinations are limited in their pressure drop andtemperature range capabilities, do not apply any other conditions to the Valve without first contacting your Emerson salesoffice or Local Business Before installing the Valve , inspect the Valve and associated equipment for any damage and any foreign material. Astrainer should be installed upstream of the Valve to prevent particles from plugging the holes in the It is important to remember to install all FB valves in a flow up The Control Valve assembly should be installed with the actuator vertical above the Valve .

10 This orientation facilitatessliding the cage assembly into the Valve without the use of special tools and rigging. In addition, vertical installationminimizes the possibility of damaging the seat ring seal ring or the mating chamfers, minimizes the possibility ofbending the stem, and greatly reduces wear on the cage. Vertical installation, therefore, significantly extends 3.
