These valves use splined shafts with actuator-mounted brackets and linear-motion actuators (see figure 1). Refer to separate manuals for instructions covering the power actuator or the manual handwheel actuator, positioner, and other accessories. Do not install, operate, or maintain a Type 9500 valve without first being fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance, and carefully reading and understanding the contents of this manual. If you have any questions about these instructions, contact your Emerson Process Management sales office before proceeding. W9224-1 Figure 1. Type 9500 Valve with Type 1052 Actuator and DVC6020 Digital Valve Controller Description The Type 9500 valve is a fully lined butterfly valve for use with corrosive process fluids or wherever stringent shutoff is required. The nitrile or PTFE liner completely isolates the valve body and shaft from the process fluid. The valve is available with conventional or Fishtail. disc designs. Note Neither Emerson, Emerson Process Management, nor any of their affiliated entities assumes responsibility for the selection, use and maintenance of any product. Responsibility for the selection, use, and maintenance of any product remains with the purchaser and end-user. D100380X012 Instruction Manual Form 24339500 Valve November 2007 Table 1.
