DESCRIPTION:
Model: Pressure Protection Valve with Integral Filter
Vehicles: Heavy-duty trucks and trailers using protected auxiliary pneumatic circuits
• Valve Type: Normally closed pressure protection valve
• Inlet Port: One 1/4"-18 NPT female
• Outlet Port: One 1/4"-18 NPT female
• Opening Pressure: 75 PSI
• Closing Pressure: 70 PSI
• Maximum Operating Pressure: 150 PSI
• Mounting: Inline installation
• Filter: Integral filter
• Function: Isolates the downstream auxiliary circuit when pressure falls below the closing threshold
• System Protection: Helps preserve air pressure for the primary braking system during downstream pressure loss
Applications:
Designed for truck and trailer pneumatic systems requiring controlled air delivery to auxiliary circuits such as air suspension, lift axles, and air-operated accessories. The valve remains closed until pressure reaches approximately 75 PSI and closes near 70 PSI to protect the upstream brake air supply.

A cross-reference listing means this part may be a suitable replacement for the listed part numbers. Always verify fitment before installation.
IMPORTANT INSTALLATION NOTES:
✔ Fully depressurize the air system before removing or installing the valve.
✔ Confirm both the inlet and outlet connections are 1/4"-18 NPT female.
✔ Install inline downstream of the protected reservoir with airflow following the valve markings.
✔ Apply air-system-compatible thread sealant without allowing sealant inside the valve.
✔ Pressurize the system and verify opening near 75 PSI, closing near 70 PSI, and no air leakage.
