Relay Valve - R12H
Ideal for heavy‑duty vehicle and trailer air‑brake systems, this R12H‑style relay valve is designed to apply and release service or parking brakes on long‑wheel‑base or multi‑axle vehicles.

Key Features & Benefits:

  • Style: “R12H” - a recognised relay valve format in heavy transport air‑brake systems.
  • Function: Rapidly responds to service‑brake valve signals, then graduates, holds or releases air pressure to the brake chambers it controls - helping maintain responsive braking and system stability.
  • Design: Built for high capacity air circuits, especially where long pipe runs or multi‑axle setups demand robust valve performance.

Applications:

  • Well‑suited to trucks, trailers or multi‑axle heavy vehicles that require a relay valve to serve rear or auxiliary axles where response time, capacity and reliability matter.
  • Replacement or upgrade when original relay valves show slow actuations, leakage, or inability to maintain proper chamber fill/vent under load.
  • Useful for fleet maintenance, service workshops, and operators needing a standardised valve format for interchangeability and ease of sourcing.

Why choose this valve?
Using a correctly‑specified relay valve like the R12H style ensures your braking circuit remains efficient, responsive and reliable. It helps bridge the gap in long supply lines, ensures the correct signal delivery to the brake chambers, and mitigates issues such as slow release, under‑performance or system lag - critical for heavy‑vehicle safety and performance.
