Retrofit your valve with a VAC Positioner
Most industrial control valves are equipped with the valve manufacturer’s “standard” positioner when the valve is first delivered. As these companies move into new generation products, they often leave behind a whole marketplace of product needs that don’t fit the application needs. When these manufacturers’ standard positioners need replacing, what choices are you offered? High prices, poor delivery, or discontinued products leave users without many options.
- VAC Gives you choices—Current design(s) and cost competitive
- Pneumatic positioners
- Electropneumatic positioners
- Digital positioners
- VAC gives you service—All of the products are in stock and supported by caring and knowledgeable employees.
- Retrofitting with a VAC positioner offers you standardization due to our flexible and versatile mounting (rotary or linear).
- VAC positioners are simple and rugged (all have aluminum housing) with quality components
VAC Positioner Options
The V100 series uses the base V100P, pneumatic positioner, and then “builds” on this basic product. For rotary or linear applications the V100 can meet a wide range of applications from standard NEMA 4X electropneumatic, to EX versions, 0-10 Volt options and special coatings such as Nickel or Tufram. Feedback is achieved with the R100 module that “piggybacks” on the positioner but maintains the NEMA 4X enclosure. This simple but very effective package can handle various rotations and strokes.
The V200 series offers the “all in one” housing, with the option for an internal Ip, and feedback (4-20 mA or switches), and in one compact NEMA 4X housing. Also adaptable to rotary or linear applications, the speed and accuracy of this product are achieved with a simple but effective design and quality components. With an option to deliver up to 50 SCFM (85 psi) and the ability to completely calibrate this unit externally, this products flexibility is ideal for standardization and retrofit.
The D400 series—Where a communications standard must be met or where the ease of auto-calibration is critical, the D400 has the options and flexibility to meet demanding industrial digital positioner needs. Available in Hart, Foundation Fieldbus, or Profibus, this unit has all the features and benefits found in microprocessor-based technology…plus more. Local push-button calibration and LCD screen make mounting, calibrating, and programming this product simple.
The D500—The D500 microprocessor based positioner incorporates the latest technology, flexibility and user-friendly features into one package. The D500 is the advanced diagnostics positioner, offering customers in depth diagnostics via its DTMs. The simple push button interface and LCD display allow for local operations and calibration of the control valve package. Hart protocol is offered as well as housing in general purpose and intrinsically safe (non-incentive). Options including analog or digital feedback, various switches, plug-in modules for emergency shutdown, universal analog input, fail freeze capability, pressure sensors for advanced diagnostics, and SIL2 approvals make the D500 a complete positioner package.
- Over 200 actuator mounting kits available (rotary and linear), custom kits if needed.
- Stock or short lead times.
- Universal approach to mounting to facilitate standardization and simplification.
- Most major brands available.
VAC stocks a wide variety of kits, has many other designs available for short lead times, and will even address making custom kits. When contacting us for kits we need to know the following minimum information: Actuator model number and size, if a linear valve the stroke length or travel. Other information like valve type and age of the actuator can help identify the correct kit. Actuators go through design revisions and top works changes; we make every effort to stay current on new designs, but the more information we obtain, the better our chances are for the right kit.
Retrofit Now Instead of Waiting on a Failure
We stock kits for all major valve and actuator companies, literally from A to Z: Your most common names, such as Bettis, Bray, Crane, DeZurik, Elomatic, Fisher, Keystone/Tyco, Morin, Masoneilan, Neles-Jamesbury, QTRCO, Rotex, Sharpe, Triac, Worcester, Xomox-and many others.
These kits have been tested and applied. We do our best to stay current on all of these OEM designs. VAC has off the shelf mounting kits and will custom design kits for specialty applications. Most of the kits are stainless steel and have all been proven before offering. We can handle rotary and linear mounting applications for valves, dampers, and any applications where a pneumatic actuator needs to be “positioned” accurately to achieve the desired control result.
