ATOS JPQ-322 22 Throttle Check Valve

ATOS JPQ-322/22 is a commonly used hydraulic control component in industrial hydraulic systems, belonging to the category of throttle check valves. Its primary function is to precisely control the movement speed of an actuator (such as a hydraulic cylinder or hydraulic motor) in one direction within a hydraulic circuit, while allowing fluid to flow freely in the opposite direction.

Applications of ATOS JPQ-322/22 in Hydraulic Systems
The ATOS JPQ-322/22 throttle check valve is mainly used in hydraulic systems where unidirectional speed control of an actuator is required. Examples include:

Containing Hydraulic Cylinder Extension/Retraction Speed: Installed in the inlet or return line of a hydraulic cylinder, it can independently adjust the extension or retraction speed of the piston rod, enabling smooth start-up and braking.
Creating Backpressure: Using the throttling function in the return line generates a certain backpressure on the return side of the actuator, improving motion stability and preventing creeping.
Speed Control Circuits: It serves as a core component in basic speed control circuits, such as inlet throttling, return throttling, or bypass throttling.
