Spring Brake Valve - SR3

This robust SR3‑style spring brake valve is designed for trailer and heavy‑duty air‑brake systems, to ensure reliable application and release of the spring brakes under normal and emergency conditions. It’s engineered to maintain safe brake function when supply pressure drops or the trailer becomes uncoupled.

Key Features & Benefits:

  • Format: “SR3 Style” spring brake valve - includes a check valve ball in the mounting nipple for added protection.
  • Application: Controls spring‑brake actuation on trailers - automatically applies the spring brakes if supply is lost or trailer is disconnected, and prevents unwanted application when service reservoir pressure is sufficient.

Applications:

  • Ideal for trailers, heavy trucks or commercial vehicles with spring‑brake actuators that require dependable parking/emergency brake function.
  • Especially relevant when replacing worn or malfunctioning valves where the original SR3‑style unit shows leaks, slow response, or loss of automatic application under fault conditions.
  • Perfect for fleet service, maintenance or retrofit installations where standardised SR3 style parts simplify stock, fitment and servicing.

Why Choose This Valve?
A correctly specified SR3‑style spring brake valve ensures safe, compliant brake operation - particularly in emergency or break‑away situations. Its acknowledged format and compatibility mean fewer surprises in replacement, reliable performance, and improved system safety.
