Pilot Relay Valve - R8P
Optimise air‑brake system control and response on long wheel‑base vehicles, converter dollies and trailers with this specialised R8P‑style pilot relay valve. Designed to reinforce and equalise the control signal across extended air circuits, it ensures consistent braking performance even for the furthest axles.

Key Features & Benefits:

  • Designed specifically as a “pilot” relay valve format (R8P style) - the control port acts to replicate or amplify the signal rather than only the reservoir supply.
  • Zero psi differential between service (control) pressure and delivery pressure - meaning minimal lag or loss in braking signal, especially important in long wheelbase setups.
  • Ensures even distribution of braking force across combinations of trailers, dollies and long wheel‑base units - contributing to improved brake lining life, stability and system uniformity.

Applications:

  • Ideal for heavy‑duty trucks, trailers, converter dollies or multi‑axle combinations where the standard relay valves may suffer from control‑signal drop or delayed actuation.
  • Especially suited when you need a valve that maintains a strong, balanced brake application from the furthest axle back to the tractor, maintaining system responsiveness and safety.
  • Suitable replacement part when existing R8P‑style pilot relay valves are worn, leaking, or causing delayed or uneven brake applications.

Why choose this valve?
Selecting the correct pilot relay valve ensures that your system’s braking signal integrity remains high - particularly on large combination vehicles where brake signal drop and timing delays are more likely. The R8P style provides a recognised format with proven performance in long wheel‑base and dolly configurations, helping maintain system reliability, regulatory compliance and consistent brake performance.
