Six-component assembly regulates pressure in tractor transmissions. Check valve function is critical to proper tractor operation. The valve allows pressurization of the transmission to between 1 and 2 PSI, enabling evacuation of oil from specific transmission chambers for shifting.
Long term strength and ability to seal correctly in harsh operating environment. By incorporating the correct materials the required sealing tolerances and temperature, fluid and wear resistance criteria were met.
