Positioner

The Apex 7000 Pneumatic Positioner provides accurate valve positioning for rotary and linear actuators in either double acting or spring return configurations. It may be used with 3-15 psi pneumatic control signals (as shown), or fitted with current-to-pressure transducers for 4-20 mA signal inputs. The modular design of the Apex 7000 allows for field retrofitting of the I/P options. The compact, lightweight positioner also conforms to NAMUR VDI/VDE 3845 mounting standards and features a UltraDome visual position indicator. The Apex 7000 is available with the following options: high and low flow spool valves and multiple feedback

The Beta Positioner is one of the best EP Positioner around.  with I/P module is intrinsically safe for FM/CSA class 1, division I, groups A, B, C, and D; class II, groups E, F, and G, and CENELEC EEx ia IIc, when  installed  with  the  appropriate  energy  limiting safety barriers (See Figure 1). It is also explosion proof for FM/CSA class II, groups E, F, and G, and CENELEC EEX d IIb + H2. Since the positioner is insensitive to upply pressure changes and can handle supply pres- sures from 30 to 150 psi a supply regulator is usually not required; however, an air filter is highly recommended

the Flowserve Logix 3800 digital positioner helps plant owners and operators maximize production while minimizing operating costs. It’s the oil and gas and chemical industries’ choice for applications that require a balance between technological sophistication and long-lasting reliability in tough environments. 

This high-precision positioner simplifies installation through easy configuration and calibration. It also facilitates improvements in process uptime, reliability and process throughput. Advanced diagnostics not only identify 

These are smart positioner and also act as PST Positioner

The PMV D3 from flowserve is a digital valve positioner with an exceptional set of features and benefits. It’s extremely simple to use due to five configuration buttons and a large, clear graphic display. The zero bleed pneumatic relay produces operational cost savings due to the unit’s very low air consumption.Optional plug-in modules offer limit switches (mechanical, proximity and P+F inductive), 4–20 mA feedback and alarm with output function. Communication options include HART®, Profibus PA and DP, Foundation Fieldbus and Wireless ISA100 (see opposite).Advanced valve diagnostics including functionality for running scheduled or manual partial strokes (PST) is available with the optional ValveSight TM package.
