Becker HPP-SB Series

Description:

The Becker Model HPP-SB Single-Acting Positioner provides accurate valve positioning when utilized with a single-acting (spring & piston style) actuated control valves. The HPP-SB accepts a pneumatic instrument signal and positions the single-acting actuator (spring & piston style) proportionally. The HPP-SB Positioner may be utilized for most valve positioning applications. HPP-SB�s are available in both reverse acting and direct acting configurations with a variety of different input signal ranges. The HPP-SB features a zero steady state bleed that minimizes emissions when the positioner must bleed to atmosphere.
