Titan 0278242 Inlet Valve Assembly

Inlet valve assembly 0278242 for SprayTech AirCoat and ED655

The 0278242 inlet valve assembly is a complete one-way valve unit that controls the flow of coating material into the pump of compatible sprayer systems. It is specifically designed for use with SprayTech AirCoat NEW; SprayTech AirCoat; and SprayTech ED655 Plus models. This assembly is installed at the pump inlet and allows fluid to enter the pump chamber during the intake stroke while preventing it from flowing back out when the pump is not running or during the pressure stroke. This function is critical for maintaining pump prime and ensuring consistent material delivery. The assembly typically includes a valve body, a sealing element such as a ball or poppet, a seat, and often a spring to assist in closing. It is manufactured from materials resistant to wear and corrosion from paints and solvents. Over time, inlet valve assemblies can become worn, clogged with debris, or have sealing surfaces damaged, leading to loss of prime, difficulty priming, or reduced pump output. Symptoms of a faulty inlet valve include the pump repeatedly losing prime, spitting or surging during operation, or difficulty drawing material from the container. Replacing a worn or damaged inlet valve assembly with this genuine part restores reliable priming and efficient pump operation. This ensures that the sprayer can draw material consistently and maintain pressure. When replacing the assembly, it is advisable to inspect the inlet filter and related seals.
