Dylect® Pressure Washer Genuine Spare Part – Valve Body (Overflow) (Located in Pump Head – Unloader/Bypass Housing) | PA66 30% Glass-Filled Nylon | Compatible Only with Flow Prime Model (Pack of 1)
The Dylect® Overflow Valve Body is a genuine spare part designed for the Flow Prime Pressure Washer’s unloader/bypass system. Positioned inside the pump head, it forms the housing for the overflow valve components and regulates pressure spikes during operation. Made from PA66 nylon reinforced with 30% glass fiber, it provides excellent strength, thermal stability, and long-term durability under sustained high pressure.
Damage to the valve body may cause auto-stop chatter, leakage, or unstable pressure. Service Note: Replace immediately if cracks or wear are visible. Genuine Dylect parts restore proper bypass operation and maintain pump reliability.
