Positioners: 

  • PMV EP-5 Positioner

Description

The P5 valve control system is modular. The basic unit of the system is a pneumatic positioner, used in single- and dual-acting applications. Modular design facilitates easy installation of additional accessories, such as an I/P converter or a feedback unit, which is isolated from the standard unit. Additional accessories can be factory-installed or mounted directly on site.

Easy calibration and service, coupled with easy adjustment of the range, zero position, and easy replacement of each component, are the main characteristics of this solution.

An I/P converter is installed directly on the position adjustment unit P5 (base module) and couples with it, to create an electromagnetic positioner EP-5. This solution does not require a separate air supply for the I/P converter, as the unit is supplied by the air from the P5 module. The standard input signal for the I/P converter is between 4 and 20 mA.

  • PMV D3 Digital Positioner
General 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.                                                                                                                                                                                                                                                                                                                                                                                                                                            D3                                             
Łatwa instalacja Instalacja jest łatwa i szybka dzięki konstrukcji z dzielonym wrzecionem, urządzenie zawiera sprzęgło cierne dla czujnika sprzężenia zwrotnego i różnorodne zestawy montażowe dostępne z magazynu, aby dopasować się do większości siłowników dostępnych na rynku. Ustawnik D3 nie jest czuły na ukierunkowanie i montuje się go w siłownikach obrotowych i liniowych.Installation is simple and quick with split spindle design, a friction coupling for the feedback sensor and a wide range of mounting kits designed to fit the majority of actuators on the market. The D3 is not orientation sensitive and mounts on both rotary and linear actuators. IP66 / NEMA 4X, 7 i 9 The strong, die-cast housing is treated with a powder epoxy, protecting the unit from corrosion and mechanical damage. Additionally, the uniquely designed strut on the cover protects the graphic display. The screw terminals for the electrical connections are located in an isolated and sealed housing to protect the electronic components should moisture enter via the conduit.
