Spring Brake Valve - SR1
Designed for dual or “split” air brake systems equipped with spring‑brake actuators, this SR1‑style valve ensures reliable parking/emergency brake performance by managing hold‑off and applying the brakes properly when required.

Key Features & Benefits:

  • Specifically engineered for use in split‑circuit air brake systems with spring‑brake actuators.
  • Provides a specific, limited hold‑off pressure to the spring brakes; if No. 1 service air pressure is lost, the valve modulates the spring brakes via the service brake valve.
  • Example trip/hold‑off pressure: around 55 PSI for certain SR1 models.

Applications:
Ideal for heavy‑duty trucks and trailers where the air‑brake system is configured with dual reservoirs (split circuit) and spring‑brake actuators. It is a reliable component for ensuring that the parking/emergency brake automatically applies when system pressure drops, and holds correctly under normal operation.

Why choose this valve?
Using the correct SR1‑style spring brake valve ensures your system maintains proper spring‑brake hold‑off pressure, protects against unintended brake application, and supports safe parking/emergency brake operation. Its standard format makes it a strong choice for fleet replacement and maintenance.
