Heavy-Duty Airless Prime Valve

A heavy-duty prime and drain valve assembly designed specifically for industrial airless paint sprayers. Constructed with a steel valve body for maximum pressure resilience, and featuring a tungsten ball thimble that delivers extended service life in abrasive coating environments. The black plastic handle is engineered for rigidity and long-cycle reliability. Confirmed compatible with popular Graco-compatible models: 210, 230, 390, 395, 490, 495, 595 and 3400. Each set includes the full valve assembly — body, thimble, handle and internal sealing elements — enabling fast, confident replacement. Colour representation may vary slightly across devices; physical measurements are accurate within ±1–3 cm tolerance.
