Transmission Check Valve Assembly

Market:	Agriculture & Off Road
Material:	Valve body - Polyphenylene Sulfide (PPS) Check ball - Nitrile (NBR) O-ring - Nitrile (NBR) Stamped washer - (PTEE) Spring - Steel

Application:
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.

Benefit:
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.
