Rotary Valve Selection Guide D102550X012 Product Bulletin 40:002 May 2015 11 Alloy Valve Guidelines Emerson Process Management expertise has combined its knowledge of metals and foundry techniques with valve user experience in creating high alloy valves that fight corrosion successfully. Guidelines have been developed to help the valve user specify alloy valves correctly. Techniques have also been implemented that verify a foundry's ability to cast alloy valves properly and has established stringent specifications that guide the foundry in providing quality results. Valve user guidelines include: Avoid the use of alloy tradenames, Don't specify wrought for cast, Forego non-destructive testing. Steps used to qualify a foundry include: Weldability tests to gauge the foundry's ability to pour alloy materials, Dedicating casting patterns solely to high-alloy service. Stringent specifications developed by Emerson Process Management include: Raw Material Composition and Quality, Heat Qualification, Visual Inspection, Weld Repair, Heat Treatment, and Nondestructive Testing. Instruments Fisher pneumatic controller C1 and 4195 series provides pressure and temperature control to standalone control loops. These pneumatic controllers provides proportional, integral, and derivative actions towards maintaining the required control loop. Electro-pneumatic transducers providing 4-20mA current input to pneumatic output for pneumatic positioners, controllers, volume booster or directly to actuators are available. Fisher 646, i2P-100, and 846 transducers provide the remote capability for connecting pneumatic instruments to control panel or control room. Fisher VBL and 2625 volume boosters used in conjunction with a positioner on a throttling control valve increase stroking speed. Fisher Wireless 4320 provides valve position monitoring that will improve visibility to valves without the need for wires. The 4320 can provide on/off control with pneumatic output option enabling easier automation of valves, again without wires. Fisher 4660 high-low pressure pilots and 377 trip valves provide pneumatic discrete control and are exida certified for use in Safety Instrument System (SIS) applications.

Typical Fisher Rotary Products DVC2000 DVC6200 on Control-Disk VALVE W8755 W9418-2 FIELDVUE digital valve controllers are communicating, microprocessor-based controllers that convert a current or digital signal to a pressure signal to operate the actuator. Through the HARTr, FOUNDATION Fieldbus™, or PROFIBUS communications protocol, the controller gives easy access to critical valve information. ValveLink™ Software allows easy access to valve assembly alerts and performance characteristics. Vital information can be obtained without removing the valve from the line. Performance Diagnostics tests, including on-line One-Button Sweep, Friction and Deadband analysis, and Trending, can be run while the valve is in service and operating. Valve Signature, Dynamic Error Band, and Step Response tests are displayed in an intuitive user-friendly environment that allows easy interpretation of data. FIELDVUE models include the DVC6200, DVC6200f and DVC6200p. The DVC6200 SIS is used for Safety applications and the DVC2000 has a local user interface.
