Positioners > BLX Positioners

The base pneumatic positioner which utilizes a unique spool valve, is a cam characterized, force balanced instrument that is simple, rugged, and very user friendly for calibration and maintenance. The NEMA 4 X housing, is cast aluminum, with an electrostatically applied polyester coating for excellent resistance against a wide range of environmental conditions. This unit operates on a standard 3-15 instrument signal (12 psi span-optional 24 psi), and can provide years of trouble free service in many tough applications. The gauge block is cast into the unit and therefore standard. The large indicator has scaling to operate in both direct and reverse directions.

By adding the internal I/P module, the base model V100P, is quickly converted to an electropneumatic positioner-at time of order or in the field-simple and effective. The I/P module is fed supply pressure air through specially designed filters, and uses a 4-20mA analog signal to convert this supply air to a 3-15 signal for mechanical positioner response. This also means that troubleshooting this product is simple and the I/P module can be replaced while mounted on the actuator. An I/P conversion kit would include the I/P module and terminal board, an o-ring to seal the board, a screw to secure the board, and a special stainless steel 1/4” plug for plugging (tightly) the I/P port on the gauge block.
