Parker NVH101K Hydraulic Needle Valve 16 Gpm 5500 Psi

Product Description

The PARKER NVH101K is a two-way hydraulic needle valve designed for precise flow regulation in hydraulic circuits. It accepts a 7/8-14 UNF thread and handles a maximum flow rate of 16 GPM at working pressures up to 5,500 psi. The valve body is steel construction, making it suited for the high-cycle, high-pressure demands of industrial and mobile hydraulic systems. It fits the C10-2 cartridge cavity, which is a common standard in hydraulic manifold and inline applications. Licensed hydraulic technicians and fluid power specialists are the typical installers for this component.

This needle valve is used in hydraulic systems that require adjustable, metered flow control on a single line. Typical applications include industrial machinery, mobile equipment hydraulics, and test bench circuits where repeatable flow restriction or shutoff is needed. The two-way configuration allows the technician to meter flow in either direction or close the circuit entirely. Its compact form factor and threaded cartridge design suit both manifold block and inline body installations across a range of equipment types.

Key Features

• Two-way flow regulation for adjustable metering or full shutoff
• Rated to 5,500 psi maximum working pressure
• 16 GPM maximum flow rate
• 7/8-14 UNF thread for standard cartridge cavity fitment
• C10-2 cavity size for compatibility with common hydraulic manifold standards
• Steel body construction for durability under high-pressure cycling

Compatibility

Designed to fit the C10-2 cartridge cavity with a 7/8-14 UNF thread. Suitable as a replacement or new-installation needle valve in any hydraulic system or manifold block machined to the C10-2 cavity standard.

Installation Notes

Installation should be performed by a qualified fluid power technician. Depressurize and de-energize the hydraulic system fully before removing or installing any cartridge valve. Use the appropriate cartridge valve socket and torque wrench; follow the manifold or body manufacturer specifications for seat torque. Inspect the cavity for damage or contamination before installation and ensure all O-rings are properly seated to prevent bypass leakage.
