Second regulator valve spring for Pettibone 30 12000

The 4012516 spring serves as a mechanical component within the second regulator valve assembly of Pettibone 30 12000 systems. It provides the necessary force to control the valve position, which is essential for maintaining specific pressure or fluid flow parameters within the transmission or hydraulic circuit. By compensating for internal system variations, this component assists the valve in operating according to the machine design specifications.

This part is compatible with the Pettibone 30 12000 model. It features a diameter of 19/32 inches and an overall length of 3 inches. These dimensions are critical for ensuring the correct spring constant and force application required for the valve to function accurately during operation.

In hydraulic and transmission systems, regulator valve springs are used to exert force against a valve spool. This action balances the fluid pressure acting on the opposite side of the valve, allowing the system to regulate flow or pressure levels. Proper spring tension ensures that the valve responds correctly to pressure changes, which is necessary for the intended operation of the machine's drivetrain or hydraulic implement functions.
