The Pressure Control Valve Spring is a helical spring that is compressed when a force is applied to it, storing potential energy. The spring applies a force that acts against hydraulic pressure fluctuations within the transmission unit, ensuring that the pressure remains consistent and within predefined limits. By modulating the tension of the spring, the valve can adjust to varying pressure requirements, thereby regulating the flow of hydraulic fluid accordingly.Attributes:• Spring rate of 23.9 pounds per inch.• The maximum solid length of the spring is 1.56 inches.• The direction of the coil is right-hand side.• Total coils are 19.5.• Active coils are 17.5.• Corrosion resistance.• Temperature resistance.• High tensile strength.Applications: The Pressure Control Valve Spring is used with the plunger in the hydraulic transmission control unit to control the flow of hydraulic fluid, ensuring that the pressure remains within optimal operating parameters.
