Flow-Adjustment Inline Hydraulic Valves
Turn the dial to gradually adjust the amount of flow. Five colored rings on the valve stem represent different flow rates. Adjust the dial until you see the color of the flow rate you need.
One-way with unrestricted reverse valves regulate flow in one direction while allowing oil to flow freely in the opposite direction. Two-way valves regulate flow in either direction.
Brass valves have better corrosion resistance than steel valves.
NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.

Precision Flow-Adjustment Inline Hydraulic Valves
A tapered needle gives you more precise control than standard flow-adjustment inline hydraulic valves. Five colored rings on the valve stem represent different flow rates. Adjust the dial until you see the color of the flow rate you need.
NPTF (Dryseal) threads are compatible with NPT threads. UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.

Adjustable Flow-Regulating Inline Hydraulic Valves
Set your flow rate and then adjust it as necessary; these valves maintain flow rate despite pressure changes in the system. Five colored rings on the valve stem represent different flow rates. Adjust the dial until you see the color of the flow rate you need.
One-way valves regulate flow in one direction. They are not recommended for systems that may have reverse flow. One-way with unrestricted reverse valves regulate flow in one direction while allowing fluid to flow freely in the opposite direction.
NPTF (Dryseal) threads are compatible with NPT threads.
