Dylect® Pressure Washer Genuine Spare Part – Valve Core (Relief) (Located in Pump Head – Pressure Relief Mechanism) | POM Engineering Plastic | Compatible Only with Flow Prime Model (Pack of 1)
The Dylect® Valve Core (Relief) is a precision-engineered component designed to regulate maximum pressure inside the Flow Prime Pressure Washer. Located within the relief valve chamber, it acts as the poppet that opens at preset pressure to control bypass flow and protect the pump from overload. Constructed from durable POM engineering plastic, it offers stable movement, wear resistance, and long-term reliability.
A worn valve core may cause pressure spikes, unstable auto-stop, or noise. Service Note: Replace during relief valve servicing or when pressure becomes inconsistent. Genuine Dylect valve cores ensure safe, accurate, and reliable pressure control.
