Tractor Transmission Check Valve Assembly

Market:

Transportation

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.
