Relay Valve  R12H

Ensure dependable, responsive brake control in your heavy‑duty vehicle or trailer air‑brake system with this R12H style relay valve - designed for service or parking brake circuits where rapid fill and exhaust of brake chambers is required.

Key Features & Benefits:

  • Format: Recognised “R12H Style” relay valve.
  • Crack/actuation pressure: around 4 PSI for many R12H versions.
  • Designed for use on rear axles, long wheelbase vehicles or multi‑axle combinations where efficient relay of brake signal is essential.

Applications:

  • Perfect for commercial trucks, trailers or other heavy vehicles that need a reliable relay valve to quickly apply or release brake chambers at the rear.
  • Ideal when replacing existing relay valves that are worn, slow to respond, leaking, or unable to maintain proper chamber fill/vent.
  • Suitable for fleet maintenance or upgrades where standardisation (R12H style) helps simplify servicing and parts inventory.

Why Choose This Valve?
Using a properly specified relay valve such as this ensures your braking system remains responsive, safe and dependable. The R12H style offers a well‑known format, widely supported across heavy‑duty transport applications - making sourcing and fitment more straightforward. Its low crack‑pressure and rightful port sizes help deliver quick chamber fill and release, which is critical in long brake‑line layouts or high‑capacity systems.
