Becker HPP-5 Series

Description:

The Becker Model HPP-5 Double-Acting Positioner provides accurate valve positioning when utilized with a double-acting piston actuated control valve. The HPP-5 accepts a pneumatic instrument signal and positions the double-acting actuator proportionally. The HPP-5 Positioner may be utilized for most valve positioning applications. HPP-5�s are available in both reverse acting and direct acting configurations with a variety of different input signal ranges. Due to its low-bleed characteristics, the HPP-5 is typically utilized when bleed gas must be discharged to atmosphere.

• Increased sensitivity as compared with older HPP-3 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 DPS Non-Bleed Device)

• Balanced seat design exhibits near zero bleed when process is at steady state

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

• 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.
