Series AV / / 3 / 4 Type AV characterizable pneumatic positioners are control devices that satisfy a wide range of applications. They provide fast, sensitive, and accurate positioning of pneumatic singleor double-acting, linear or rotary motion actuators. A mechanical connection from the actuator to a position feedback cam in the positioner establishes actual position. Three characterized segments on one cam provide application flexibility by establishing various relationships between input signal and actuator position. The relationships provided by the segments are square root, linear, and square. Using the cam and the zero, span and gain adjustments, the actuator responds with characteristics specific to an application. An optional manifold assembly provides an integral shutoff and equalizing valve. This isolates the positioner from a double-acting actuator (with manual override) without removing the positioner from the process. The manifold also provides disposable filter cartridges that insure fast servicing and minimum downtime. Manifolds also contain three gage ports for mounting one instrument and two output gages. A supply gage is available and must be piped into the supply line by the user. Type AV positioners are pneumatic positioners that use a pneumatic input to control the pneumatic output. Type AV and AV3 positioners are electropneumatic, with Type AV and AV3 using an I/P (current-to-pneumatic) converter to accept a 4 to ma input signal and convert it to a pneumatic output. Type AV4 positioners use the I/P converter to operate with a contact input signal for jogging the final control element. Explosion proof I/P converter The AV7 positioner includes an explosion proof I/P converter mounted to an adapter block manifold. The adapter block manifold is bolted to the outside of the main positioner housing. The unit is a Type AV positioner with the electric to pneumatic (4 to ma to.7 to 3.4-kPa (3. to 5. psig)) conversion occurring within the externally mounted I/P converter. The 4 to ma input signal wires are connected through an explosion proof conduit entrance on the I/P converter. If no electrical connections are made within the main housing, the entire positioner can be considered suitable for application in the hazardous locations shown on the I/P label. Refer to Fig. 6, page for the external and mounting dimensions of the positioner. NEMA 4X The positioners are available with a NEMA 4X housing. To maintain the NEMA 4X classification, the positioner shall meet special installation requirements described in the NEMA 4X mounting kit. Suitable piping must be attached to the vent opening and vented in a manner to prevent the entrance of water under pressure (for example, from a hose). Additionally, the conduit connections must be suitable for a NEMA 4X rating. Some nomenclature options include a high temperature type AV positioner that can be operated and stored at temperatures up to 7 C (5 F). Type AV positioners are available with an explosion proof I/P converter, external to the housing, that is mounted on an adapter block manifold. The performance series provides a high flow gain pilot valve body having square ports that provide a maximized air flow for a small motion of the valve stem. DS/AV34 EN Rev. G Series AV / / 3 / 4

Series AV / / 3 / 4 Operation Type AV positioners operate by balancing opposing forces. Fig. 3 is an operational diagram of the positioner. A balance beam, hinged at one end and connected to the pilot valve at the other, is acted upon by two forces: Upward force of the signal diaphragm assembly Downward force from the range spring A change in input signal changes the force exerted by the signal diaphragm, moving the balance beam, in turn moving the pilot valve. The pilot valve supplies and / or exhausts air to the actuator that ultimately changes its position. The change in actuator position is fed back to the positioning cam. The positioning cam moves, changing the tension of the range spring until a balanced condition once again exists. The input signal pressure determines the diaphragm force. The Type AV positioner uses an external input pressure (either.7 to 3.4 kpa (3. to 5. psig) or.7 to 86. kpa (3. to 7. psig). Types AV and AV3 positioners internally generate the input signal pressure using an I/P converter. The range spring force is a function of the shape and position of the cam. The cam is coupled to the cam shaft that is connected through linkage (or coupling) to the actuator. Therefore, range spring tension is a function of the actuator position. Type AV pneumatic positioner The Type AV positioner receives an external pneumatic signal and converts it to a pneumatic output. This output produces the motive force that positions the power actuator. Type AV and AV3 4 to ma I/P positioners The Type AV and AV3 positioners receive a current input (4 to ma) from the control device and convert the signal to a pneumatic signal. This pneumatic signal is converted to a pneumatic output that produces the motive force that positions the actuator. The Type AV fails open / closed and the Type AV3 fails in place on loss of current input signal.

G Series AV / / 3 / 4
Type AV4 pulse input positioner The Type AV4 positioner receives a contact closure input (pulse) from a control device and converts the signal to a pneumatic signal. This pneumatic signal is converted to a pneumatic output, producing the motive force that positions the actuator. Position transmitters Two types of position transmitters are available on Type AV, AV and AV3 positioners. The potentiometric position transmitter uses a high durability plastic film potentiometer to indicate the position of the cam shaft. The resulting resistive value is a function of the shaft position. The resistive output can be used for additional control purposes. The 4 to ma position transmitter uses a high durability plastic film potentiometer to indicate the cam shaft position. The resulting resistive value is sent to an electronics assembly that produces a proportional 4 to ma signal. This signal can be used for additional control purposes. Standard Position error (%) Performance series O Supplying O Exhausting 5 5 5 Performance series O Supplying O Exhausting Standard 5 5 5 5 5 5 Performance series The performance series provides a high flow gain pilot valve body with square ports that provide maximized air flow for a small motion of the pilot valve stem. A relatively small error signal can therefore cause a relatively large change in output air flow to the actuator. This feature is useful when driving larger actuators that might otherwise be insensitive or slow to respond to small signal changes. Compared to other positioners on the market, the standard Type AV positioners have a high delivery capacity. The flow gain curves shown in Figs. 4 and 5 show output air flow versus input error signal for the standard and high-gain performance series positioners. Figs. 4 and 5 show that the large signal maximum air flow for both the standard and performance series positioners is about the same. The performance series positioners achieve maximum flow capacity at a much smaller error signal. Avoid using a performance series positioner on a small actuator as it could cause instability. 5 Output air flow (SCFM) Fig. 4: Output air flow versus error signal - standard and performance series Output air flow (SCFM) 4 8 6 4 Performance series Standard O Supplying 4 6 Position error (%) 8 Fig. 5: Expanded first quadrant view of Fig. 4 Series AV / / 3 / 4 DS/AV34 EN Rev.

Electropneumatic pulse input positioner type AV4 The AV4 electronic input positioner operates with a contact signal for jogging the final control element. This enables operation of pneumatic valves in a jog mode similar to electronic valve operation. Designed to meet the special requirements of interfacing with state-of-the-art computer and microprocessor-based control systems, the AV4 utilizes an advanced, pneumatic motor-to-pneumatic signal converter. In one compact package, it replaces three separate components: a motor-to-motor pneumatic converter, a pneumatic positioner, and a position transmitter.
