Backflow-Prevention Inline Hydraulic Valves
Also known as check valves, these open to allow flow in one direction and close when flow stops or reverses.
Valves with a poppet have internal components that can handle any flow rates. The higher the flow rate of the hydraulic fluid coming into the valve, the lower the pressure the fluid is as it leaves the valve.
UN/UNF (SAE) thread connections have straight threads and are also known as O-ring Boss fittings.
UN/UNF (ORFS) threads are also known as O-ring face seal threads.
