Bypass valve is installed on the spin-on fuel and oil filter. When the filter element is blocked and the oil pressure reaches 100±20 kPa, the bypass valve will automatically open to allow the oil to flow through.

• Stable function throughout the service life
• Valve pressure is suitable for engine parameter requirements
• The bypass valve can also play a role at low temperatures (anti-frost) and keep it completely sealed;
• Provide the best fuel supply for the engine.
