Dry Bulk Check Valve Inspection
Prevent expensive $12,000 PTO blower seizures. Standardize silicone flapper seat audits, air manifold check valve cleaning, thermal discharge burns prevention, and cross-contamination defense.
Flapper Seat Seal Integrity
Flapper check valves prevent pressurized powder from blowing backwards into the truck blower when the engine stops. Inspect Viton or silicone hinge seals for embedded grit every 90 days.
Thermal Burn Hazards
Compressed discharge air exiting PTO rotary lobes exceeds 325°F. Bare metal hot-air hoses and uninsulated check valve housings pose severe third-degree burn risks to drivers.
Secondary Relief Valves
Tank vessels are typically rated for 15 PSI working pressure. Blower relief valves must pop open at 16 - 18 PSI to prevent catastrophic pressure vessel weld ruptures.
