Protect air supply distribution with the WABCO Air Brake Pressure Protection Valve. This pressure protection valve limits maximum operating pressure in the air brake system to about 155.19 psi, providing a safeguard against over‑pressurization in regulated brake circuits. The compact valve body weighs approximately 0.54 pounds and is built to OE specifications for pressure protection components used in commercial vehicle air brake systems. It integrates into protected air circuits to help isolate auxiliary paths and preserve brake system pressure where needed. By regulating air pressure peaks, the WABCO R90555396 air brake pressure protection valve enhances system integrity and helps prevent premature component fatigue.
