The Newstar Air Brake Pressure Protection Valve is a PR-4-style component designed to safeguard the air supply within heavy-duty braking systems. This normally closed valve is preset to 85 PSI, ensuring that primary reservoir pressure is maintained before allowing air to flow to auxiliary or secondary circuits. Its 1/4-inch NPT ports allow for a direct-fit installation into standard truck and trailer air lines. By automatically closing if pressure drops below the setpoint, this Newstar 286500 valve prevents a total loss of air in the event of a downstream accessory failure.
