• Founded in 1939 in Sweden, PMV began producing linear positioners in 1968.  12 years later PMV developed the P-1500 rotary positioner which is still in production today.  Consequently in 1991 PMV entire focus was put on valve positioners and limit switch boxes.  Most noteworthy PMV is now a wholly owned subsidiary of Flowserve corporation.

    With more than 1 million installed positioners around the globe, PMV can be trusted for reliability, accuracy, and durability.  As a result, the company's products can be found in a multitude of industries including; Oil & Gas, Water & WasteWater, Pulp & Paper, Chemical, Refining, Food & Beverage, Pharma, Primary Metals, and OEMS.  

    First of all PMV has 3 distinct categories of positioners.  Pnuematic, Electro-Pneumatic, and Digital.  Most of all we hope to offer the end user a good glimpse of what PMV has to offer and the distinct advantages of the products and it applications.

    FloSource has been an authorized PMV-FlowServe agent for sometime.  In conclusion, we stock entire units and can also offer parts and technical assistance. We look forward to working you Today.


  • PMV Pneumatic Positioners

  • The foundation of the PMV Valve Control System is the PMV P5 pneumatic positioner. Performance of this unit has been enhanced with the special high gain/high capacity spool valve assembly providing very quick and accurate actuator/valve response.  Available Signal ranges include but not limited to: 3-15 PSI, 6-30 PSI, and Split Ranges.  Options include gauge blocks, feedback units, and a external zero adjustment.  

  • PMV Electro-Pneumatic Positioners

  • The EP5 electropneumatic positioner is adapted from the PMV P5 pneumatic positioner. This compact and sturdy unit is designed for maximum performance in all types of environments. The EP5 is available in Standard, Intrinsically Safe and Explosion Proof versions. A modular feedback unit F5 allows for the addition of limit switches and/or position transmitters.

  • PMV Digital Positioners

  • PMV-FlowServe offers two distinct digital positioners in the market.  The D3 and D20 are both rugged and simple in design.  Each has unique features that are outlined below.  Contact FloSource for more information.

    The PMV D3 is very simple to inistall,use and operate due to a large graphic display and auto calibrate feature.  It will drive the actuator to its open and close limits as well as calibrate its PID control settings to achieve precise valve control.  Configuration via five large push bottoms is intuitive, reducing set up times . The computer-optimised pneumatic relay with piezo-electric valves offers excellent dynamic performance combined with low air consumption. The combination of these features result in lower energy consumption and considerable savings, while maintaining a high degree of valve performance. Communication via HART®, Profibus or Foundation Fieldbus is possible. Optional plug in modules offers limit switches, alarm and feedback function

    The D20 is a compact digital positioner that is very simple and quick to install and operate. To calibrate it, simply press the button for 5 seconds, D20 will auto-calibrate and tune itself in a few seconds. D20 can be fitted with optional 4-20 mA feedback transmitter and limit switches. Optional LCD with menu is available on D22. HART communication is optional. For visual indication you can select between flat arrow indicator or a dome indicator.
