Spiral Perforated Metal – Center or Outer Tubes
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.
