The details are:
Type: Needle Valve
Brand/Manufacturer: FD-LOK
Material: SS316 (Stainless Steel 316)
Size (Nominal): 1/4"
Connections: FNPT x FNPT (Female National Pipe Thread on both inlet and outlet)
Pressure Rating: 6000 PSI (Pounds per Square Inch)
Key Features and Application
This specific configuration is highly common in instrumentation and process control due to its robust construction and threading standard:
SS316 Material: Offers excellent corrosion resistance, making it suitable for a wide range of fluids, including aggressive chemicals, in oil & gas, chemical processing, power generation, and other industrial applications.
FNPT Connections: The 1/4" Female NPT threading is a widely accepted standard for connecting to piping or tubing via a male-threaded pipe fitting or tube fitting connector. Since both ends are FNPT, it is known as a Female-Female (FF) pattern valve.
6000 PSI Rating: Indicates it's built for high-pressure applications, typical in process lines, sampling systems, and gauge isolation.
Needle Valve Function: Needle valves use a finely tapered stem that moves into or out of a seat to regulate flow, providing precise, repeatable throttling (flow control) rather than just on/off operation.
