3 Product Bulletin The Type 585C Linear Piston Actuator The Type 585C linear piston actuator is a powerful, double-acting actuator that provides accurate throttling or on-off operation for sliding-stem control valves. The Type 585C piston actuator family is available in sizes 25 to 130 to cover a wide range of thrust and travel length requirements. It can be used with switching valves for on-off control, or with the Fisher 585C Actuator DVC6000 Series digital valve controller or 3600 Series positioner for throttling applications. The Type 585C has a wide-range of supply pressure capabilities, up to 150 psig. As the Type 585C is double-acting, the positioner supplies air to both sides of the piston, resulting in stiff, precise movement and control. The 585C piston actuator is also available in a long stroke version with travel capabilities up through 610 mm (24 inches). Type 585C Features and Advantages See table 1. Table 1. Type 585C Features and Advantages Features Advantages With air supply capability of up to 150 psig, the Type 585C can produce up to High thrust capability 111,000 Newtons (25,000 pounds) thrust to overcome high valve unbalance. Special constructions can produce thrusts of up to 137,000 Newtons (30,800 pounds). Depending on size, strokes of up to 203 mm (8 inches) (standard) are available. Long stroke Longer travels of up to 610 mm (24 inches) are available upon request. The Type 585C is available in standard sizes 25, 50, 60, 68, 80, 100, and 130. Wide range of sizes Larger cylinder sizes are available for special applications. Depending on size, the Type 585C can be mounted to yoke boss diameters of 2-1/8 Valve mounting inches through 5-inches, and valve stems of up to 1-1/4 inch diameter. Special capability constructions will accommodate a 7-inch yoke boss and a 2-inch valve stem. Positioner mounting capability High frequency response Stiff construction Handwheels Bias springs Universal NAMUR mounting provides a consistent mounting method for size 25 through 130 actuators. This mounting capability provides vibration resistance per ISA-S The double-acting construction of the Type 585C allows quick response to instrument signals. Pressure on both sides of the piston, plus the relatively small volume of air within the cylinder, results in stiff, precise positioning. Type 585C size 25 and 50 actuators are available with a top-mounted handwheel. All other 585C actuator sizes can accommodate a side-mounted handwheel. The sizes 25 and 50 are available with bias springs. A bias spring under the piston fully retracts the actuator stem upon loss of supply air, while a bias spring on top of the piston fully extends the actuator stem. The spring bias mode is easily reversed without the need for additional parts. 3

4 585C Actuator Product Bulletin E0409 / IL Figure 3. Type 585C Piston Actuator Without Springs Principle of Operation 585C The Type 585C piston actuator (figures 2 and 3) uses a piston that moves inside the actuator cylinder. An O-ring (see figure 2) provides a seal between the piston and the cylinder. From an equilibrium state, the actuator reacts to a force unbalance that is created by increasing supply pressure on one side of the piston,and decreasing it on the other. This moves the piston up or down, and results in a repositioning of the valve control element. E0410 / IL Figure 4. Type 585C Piston Actuator with Handwheel Actuator with Handwheel (figures 4 and 13) The handwheel version can be used to open or close the valve manually (either during normal operation or in an emergency), to position the valve at any point in the stroke, or to act as a travel stop. Size 25 and 50 actuators use an integral top-mounted handwheel. See figure 13. Size 60 to 130 actuators use a side-mounted handwheel, and come with a spring-loaded ball detent which prevents vibration from changing the handwheel setting. Handwheels for most types are either 203 mm (8 inches) in diameter with beveled gears or 432 mm (17 inches) in diameter with worm gears. 4

Type 585C Piston Actuator with Spring Return W2795 1/IL Actuator with Spring Return (figure 5) Type 585C size 25 & 50 actuators are available with bias springs. The Type 585C actuator with bias spring has the spring under the piston and fully retracts the actuator stem upon loss of cylinder pressure. The bias spring in the Type 585CR actuator is on top of the piston and fully extends the actuator stem upon loss of cylinder pressure. No additional parts are required to convert from one actuator type to the other. Figure 6. Type 585C Long-Stroke Actuator Type 585C Long-Stroke Construction When especially high thrust or long stroke is required, the Type 585C Long-Stroke piston actuator is the answer (see figure 6). The versatility of the Long-Stroke version allows accommodation of 16 different valve travels, up through 610 mm (24 inches). Available thrusts are impressive too, with thrust capability of up to 137,800 newtons (30,800 lbs). 5

6 585C Actuator Product Bulletin Instrument Selection An excellent selection of sensitive and accurate instruments is available for Type 585C piston actuators. These include the DVC6000 Series digital valve controller, as well as the 3600 Series pneumatic (P/P) and electro-pneumatic (I/P) positioners. DVC6010/6020 Digital Valve Controller FIELDVUE DVC6000 Series digital valve controllers, figure 7, are communicating, microprocessor-based current-to-pneumatic instruments. In addition to the traditional function of converting a current signal to a pressure signal, DVC6000 Series digital valve controllers, using HART communications protocol, give easy access to information critical to process operation. This can be done using a Model 275 HART Communicator at the valve or at a field junction box, or by using a personal computer or a system console within the control room. Using HART communication protocol, information can be integrated into a control system or received on a single loop basis. DVC6000 Series digital valve controllers can be used on single- or double-acting actuators. The digital valve controller receives feedback of the valve travel position plus supply and actuator pneumatic pressure. This allows the instrument to diagnose not only itself, but also the valve and actuator to which it is mounted. This provides you with very cost effective maintenance information, so that required maintenance can be performed on the instrument and valve when there really is a need. Wiring is economical because DVC6000 Series digital valve controllers use two-wire 4 to 20 ma loop power. This provides for low cost replacement of existing analog instrumentation. The DVC6000 Series digital valve controller s two-wire design avoids the high cost of running separate power and signal wiring. Principle of Operation DVC6010/6020 DVC6000 Series instruments receive a set point and position the valve where it needs to be. See figure 8. The input signal provides electrical power and the set point simultaneously. It is routed into the terminal box through a twisted pair of wires. W7960 / IL Figure 7. Type DVC6010 Digital Valve Controller Mounted on Type 585C Piston Actuator The input signal is then directed to the printed wiring board assembly where the microprocessor runs a digital control algorithm resulting in a drive signal to the I/P converter. The I/P converter assembly is connected to supply pressure and converts the drive signal into a pressure output signal. The I/P output is sent to the pneumatic relay assembly. The relay is also connected to supply pressure and amplifies the small pneumatic signal from the I/P converter into a single larger pneumatic output signal used by a single-acting actuator. For double-acting actuators, the relay accepts the pneumatic signal from the I/P converter and provides two pneumatic output signals. The change in relay output pressure to the actuator causes the valve to move. Valve position is sensed through the feedback linkage by the instrument s travel sensor. The travel sensor (or potentiometer) is electrically connected to the printed wiring board to provide a travel feedback signal used in the control algorithm. The valve continues to move until the correct position is attained. 6

DVC6000 Series Digital Valve Controller Block Diagram 3600 Series Positioner 3600 Series pneumatic (P/P) and electro-pneumatic (I/P) positioners are used in combination with either single or double acting actuators to accurately position control valves used in throttling applications. These accurate and vibration-resistant positioners provide a valve position proportional to a pneumatic or a dc current input signal. Low steady-state air consumption contributes to efficient operation. The Type 585C piston actuator can be controlled with the Type 3610JP or 3611JP pneumatic (P/P) positioner, and the 3620JP or 3621JP electro-pneumatic (I/P) positioner. Principle of Operation 3600 Series A switching device is required to control the loading and unloading of supply pressure. A 4-way solenoid or a 3600 Series positioner can be used for throttling service. The P/P positioner accepts a pneumatic input signal, whereas the I/P positioner accepts a dc current signal from a control device. W4919 / IL Figure 9.

As a result, the actuator stem retracts and the feedback arm pivots counterclockwise reducing the force applied to the summing beam by the range spring. As the actuator stem retracts, the range spring force to the summing beam continues to reduce until the summing beam torques are in equilibrium. At this point, the actuator stem is in the correct position for the specific input signal applied. ZERO ADJUSTMENT W4901 1*/IL The I/P positioner is a combination of a P/P positioner with a current-to-pressure converter. The converter provides a 0.2 to 1.0 bar (3 to 15 psig) output pressure proportional to the 4 to 20 milliampere input signal. The 0.2 to 1.0 bar (3 to 15 psig) output pressure becomes the input signal pressure to the P/P pneumatic positioner. Figure 10. Adjustment for 3600 Series Positioners The P/P positioner is a force-balanced instrument that provides an actuator stem position proportional to the pneumatic input signal, as shown in figure 11. For direct action, input signal pressure from a pneumatic instrument is channeled to cavity A in the input module. An increase in input signal pressure results in a downward force on the summing beam, pivoting the summing beam counterclockwise. This moves the flapper slightly toward the nozzle, increasing the nozzle pressure. As nozzle pressure increases, the relay beam pivots clockwise, causing relay B to increase upper cylinder pressure and Relay A to exhaust lower cylinder pressure of the actuator. As a result, the actuator stem extends and the force applied to the summing beam by the range spring increases as the feedback lever rotates clockwise. This force, which opposes the downward force on the summing beam caused by the increasing input signal pressure, continues to increase until the summing beam torques are in equilibrium. At this point, the actuator stem is in the correct position for the specific input signal applied. For reverse action, input signal pressure is channeled to both cavities A and B. An increase in signal pressure results in an upward force on the Accessories Type 304 Electrical Valve Stem Position Switch A cam operated limit switch assembly that can house from one to six snap-acting switches. The position switch shaft is rotated by linear motion of the valve stem and each cam can be adjusted to activate its switch at the proper travel. 377 Series Trip Valve Used when a specific valve fail action is required when supply pressure falls below a specified pressure. Should supply pressure fall below the trip point, the trip valve can be set to cause the actuator piston to fail up, fail down or lock-in-last position Series Electronic Position Transmitter The position transmitter provides an electrical signal that is proportional to the valve stem position. Depending on the type of transmitter ordered, it provides a transmitter signal only, position switches only, or a transmitter signal with position switches for accurate valve position indication. GO Series Limit Switches (Size 60 to 130 only) Can be mounted on the yoke cover plate to electrically indicate open or closed positions of the valve. 8
