Plunger
Bendix

A precision plunger designed for reliable linear actuation within air system control valves, purge assemblies, and regulator mechanisms. This essential component delivers consistent open‑and‑close movement under varying pressures, contributing to predictable response times and stable valve operation. Its tight tolerances and smooth surface finish minimize play and wear, extending service life and reducing the likelihood of chatter or sticking during cycling. In service, the plunger helps maintain proper port alignment, seating pressure, and preload, which are critical to accurate regulation, leak control, and diagnostic stability. While compatible with a broad range of Bendix interfaces, it is particularly suited for replacement in control valve assemblies where worn or damaged actuation surfaces degrade performance. VMRS 013-010-080 identifies its function within the control devices and regulators subset, reinforcing its role as a versatile, high‑reliability component for daily maintenance and repair operations across heavy‑duty fleets.
