Norgren Fluidics  - 4LD-010-D00+ - 4LD-010 - Check Valve, Miniature.

A check valve is the simplest type of directional control valve used in hydraulic systems. Check valves stop the flow of fluid in one direction and allow free flow in the opposite direction. They are also known as non-return valves. Check valves may be used as prefill valves, bypass valves, pre-tensioning or protection of hydraulic components against pressure surges.

Extremely low crack pressures 10-32 UNF or barbed tube connections Direct in-line mounting Control flow direction in medical equipment, instrumentation systems, and in miniature pneumatic control systems.
