Parker Hannifin 4M-NP6LK-SSP Needle Valve Screwed Bonnet

Parker Hannifin 4M-NP6LK-SSP Needle Valve Screwed Bonnet is a precision flow-control valve designed for fine regulation of liquid or gas flow in hydraulic and pneumatic systems. The screwed bonnet arrangement provides a robust, serviceable sealing interface, while the needle-valve core enables small, repeatable adjustments for accurate metering and reliable shutoff. As part of Parker Hannifin’s needle valve lineup, the 4M-NP6LK-SSP is suited for applications where tight flow control and leak-tight performance are essential, such as instrumentation loops, analytical test setups, or process lines requiring configurable flow isolation. The compact form factor and screw-on bonnet design support installation in restricted spaces and facilitate field serviceability when calibration or reseating is needed. This description identifies the product by its model and manufacturer, ensuring buyers can match it to the correct Parker Hannifin catalog entries and recognize its role as a precision valve in fluid handling systems.
