The HPP-4 pneumatic valve positioner delivers precise proportional control for double‑acting piston actuators by converting standard pneumatic input signals into accurate valve travel. It supports both direct and reverse action configurations with versatile signal ranges, ensuring broad compatibility with diverse process control systems. Combined with BPS emission elimination technology and optional VB‑250 volume booster integration, it achieves eco‑friendly operation and superior dynamic performance for high‑speed, large‑capacity valve applications.
The Becker™ HPP-5 double-acting pneumatic positioner achieves proportional, precise valve travel control for piston-style double-acting control valves, offering flexible direct/reverse action setups and multiple signal range options for universal process use. Featuring ultra-low bleed consumption, this positioner is ideal for installations where small volumes of vent gas are allowed to exhaust into the surrounding air.
The Becker HPP-SB is a high-pressure pneumatic positioner customized for single-acting piston actuators in natural gas pipelines and oil & gas gathering stations.
The Masoneilan 4700E/4800E electropneumatic and 4700P/4800P pneumatic positioners are proven control‑valve accessories. Their precision feedback‑cam design ensures accurate positioning, fast response and customizable control curves for rotary or reciprocating actuators. The cam can be fitted directly to rotary shafts, while a rugged lever‑turnbuckle assembly connects stem movement for linear actuators.
