Advanced Digital Positioner
The V100 series product (BLX) is a proven performer and a complete package of pneumatic and electropneumatic valve positioners. The R100 stackable feedback module can complete a NEMA 4X package. This series offers a number of special features including Nickel or Tufram® coating. Flexible mounting to rotary or linear actuators is made easy with the "quick connect" couplings.
Tufram® is a registered trademark of General Magnaplate Corporation
Cast Aluminum, polyester housing that is NEMA 4X rated. All stainless steel retained fasteners. A thick stainless steel cam that is double locked with sturdy cam nut. The bottom plate helps absorb vibration.
Screwdriver slots in the span and zero ferrules, along with an external zero adjustment, helps make setting up the positioner simple. The minimum interaction between zero and span mean you can make a span adjustment without always returning to zero with each adjustment saving you valuable time.
Special cams, range springs, various pilots, spindles (drive connectors), gauges, dome indicators, and position feedback are examples of the options that are available from VAC. In addition, special requests are welcomed and encouraged-so please give us an opportunity to help you with any application need.
The pilot valve assembly can be easily cleaned (dry alcohol base) by removing one screw and blowing the assembly clean. The unique O-ring gasket prevents loss of individual O-rings in the cleaning process. The assembly can then be easily re-installed in only one direction, with a design that automatically "pinches" the upper lever leaf spring that is used to help stabilize the pilot. I/Ps can be changed, removed, converted in minutes and the I/P test points on the small connection board make checking the I/P or the circuit very simple.
One housing for pneumatic or electro-pneumatic, where I/P can be installed, removed or converted at any time-while still mounted on the actuator. Various mounting capabilities - rotary or linear. The standard indicator can be reversed to direct or reverse acting and always show the proper scale (0-100%). Flat or raised indicators. F05 mounting hole pattern with multiple drive options that can be field converted...and more!
This compact NEMA 4X valve positioner allows for an internal I/P, switches, and a 4/20 mA transmitter, all in one compact, rugged, die-cast, aluminum housing. The flexibility to add, remove, replace, and calibrate this valve positioner is very user-friendly.
All in one housing

The ability to calibrate a positioner is important. Time can be money, and with the V200 positioner, calibration is made simple, easy, and NOT time-consuming. Both Zero and Span can be adjusted without removing the cover, and the single spring has very little interaction.
Being able to get all of the needed options from a single product can be a real benefit. For basic pneumatic to various Ip options (standard, IS, EX, FF, Gas approved, 0-10V) and adding valve position feedback into the one compact housing is a benefit. The flexibility of going from one type to the other in minutes saves time and money. Quality construction of each product equals accurate control and long service life.
As the need for valve position feedback grows, the V200 positioner allows for very accurate feedback options. From switches to 4/20 transmitter, these components fit very neatly and simply into the one NEMA 4X housing.
The flexible mounting allows for mounting to many actuators, built in gauge block, various pilot assemblies, special cams, beacon indicator, and more are available from one source-one product.
