摘要： A relief valve includes a valve body having an inlet and an outlet; a passageway formed between the inlet and the outlet in the valve body; a valve tube positioned in the passageway having a generally cylindrical portion including a first outside diameter and a second generally cylindrical portion including a first inside diameter that is larger than the first outside diameter; a valve seat; and a spring positioned about at least a portion of the valve tube and biasing the valve tube away from the valve inlet to seal against the valve seat. The valve tube and valve seat prevent flow through the passageway when pressure at the inlet is below a predetermined pressure and wherein the valve tube moves axially away from the valve seat at the predetermined pressure allowing flow through the passageway from the inlet to the outlet.

摘要： A check seat assembly includes a check valve seat with a bi-pass passage in parallel with a check valve passage of the check seat assembly to meter flow and maintain stability of a hydraulic system, such as a hydraulic cylinder. The check valve may include an o-ring seated in a V-shaped groove. The check seat assembly may allow flow from a pump to a hydraulic cylinder to freely pass through the check valve to pressurize one side of a piston of the hydraulic cylinder, such as a front side of the piston to retract a corresponding rod connected to the piston.
