Description:

The Becker Model HPP-4 Double-Acting Positioner provides accurate valve positioning when utilized with a double-acting piston actuated control valve. The HPP-4 accepts a pneumatic instrument signal and positions the double-acting actuator proportionally. The HPP-4 Positioner may be utilized for most valve positioning applications. HPP-4�s are available in both reverse acting and direct acting configurations with a variety of different input signal ranges. The HPP-4 is typically utilized when Bleed to Pressure System (BPS�) may be used to completely eliminate atmospheric bleed emissions. Additionally, the HPP-4 is typically utilized for high speed applications and large volume control actuators that both require VB-250 volume boosters.

Benefits
  • Increased sensitivity as compared with older HPP-2 design.

  • Better resolution and positioning capabilities for improved process performance.

  • Zero bleed when control valve is full open and full closed (requires addition of NBV or PS Non-Bleed Device)

  • Becker�s unique Bleed to Pressure System� feature allows for complete elimination of atmospheric bleed gas by maintaining vent gas within the process piping.

  • Capable of high speed stroking when paired with VB-250 Series Volume Boosters

  • Simple, reliable �seat & nozzle� design

  • Stable, accurate positioning with minimal overshoot

  • Vibration resistant design will perform in the most demanding applications and maintain calibration. No annual adjustments required.

  • Anodized AL 2024 Aluminum and Stainless Steel construction provide rugged durability for long life.
