Hydraulic Flow Regulators

Aerospace hydraulic fluid conveyance systems are often subjected to widely varying pressure changes and actuator loadings throughout an operating cycle. Parker Stratoflex’s hydraulic flow regulators are designed to control hydraulic actuator velocities and provide precisely timed rates of flow. Typically found in dynamic applications, such as aircraft landing gear systems, Stratoflex flow regulators allow for rapid actions, such as gear retraction, while minimizing dynamic forces to reduce structural strain.
As fluid passes through the valve in the regulated direction, sets of predetermined pressure drops and springs exert pressure and counter-pressure on a precisely engineered piston in a throttling action that increases or decreases the flow velocity. As a result of the piston’s movement, only the correct rate of flow is permitted to pass through the regulator which provides a constant upstream or downstream pressure, depending on application.
