Titan 730-511 Inlet Valve Housing

Part number 730-511 is an Inlet Valve Housing specifically engineered for use across an exceptionally extensive range of professional sprayer systems. This precision-machined component is compatible with RentSpray Plus, 650, and 600; Performer 640 i Airless Sprayer; impact X 410, Impact 410, and Impact 400 Airless Sprayer; Epic 690 HPG, 660HPX, and 447HPX; Advantage 500 and 400; 690 GXC, 660 XC, 640 IX, 640 i, 550 XC, 540 IX, and 440 IX Airless Sprayers. Service documentation for the Epic 690HPG details that the inlet valve housing is part of the fluid section assembly, containing the ball and seat that form the one-way check valve allowing material to enter the pump chamber.

The inlet valve housing is a critical component that provides the machined chamber for the inlet valve ball and seat. During the suction stroke, the ball lifts off the seat to allow fluid into the pump. During the pressure stroke, the ball seats against the housing to prevent backflow, maintaining prime and ensuring consistent pressure. The housing is manufactured from durable materials with precision-machined surfaces to ensure proper sealing and long service life.

This housing is subjected to continuous pressure cycling, vibration, and chemical exposure. Failure modes include thread damage, corrosion, cracking, and wear of the sealing surface. A damaged inlet valve housing can cause loss of prime, pressure fluctuations, and poor spray performance. Replacement with genuine 730-511 inlet valve housing restores proper check valve function and ensures reliable operation across this extensive family of professional spray equipment.
