HVNF6-15K 2-Way Straight Needle Valve, 3/8 Inch Female NPT Ports

Specify the HVNF6-15K Two Way Straight Needle Valve for industrial assemblies that require 3/8-inch female NPT connections and bidirectional flow capability. This V Series model features a 316 stainless steel body, a 17-4PH stem, and a listed 0.25-inch (6.35 mm) orifice.

For OEM engineers, equipment builders, and purchasing teams, these details provide a clear basis for reviewing connection compatibility, materials, and installation space.

Use the complete HVNF6-15K catalogue number in your inquiry so drawings, configuration details, and commercial offers refer to the correct valve.

Three Features to Include in Your Equipment Specification

3/8-inch female NPT connections.
The stated connection type gives assembly teams a defined interface for selecting mating fittings. Confirm the fitting specification and installation requirements before completing the pipework design.

Flow capability in either direction.
Like the other V Series valves, the HVNF6-15K supports bidirectional flow. This provides flexibility when assessing its position within the circuit.

Specified body and stem grades.
The 316 stainless steel body and 17-4PH stem establish material references for procurement. However, suitability still depends on the working medium, temperature, and complete wetted construction.

HVNF6-15K Dimensional Reference

The following dimensions come exclusively from the HVNF6-15K row. Letter labels refer to the corresponding manufacturer drawing.

Values are reproduced as listed. The connection is specified as 3/8-inch female NPT; its nominal size should not be treated as the measured thread diameter. Refer to the drawing for feature locations and the definition of H*.

Review Temperature and Media Compatibility

The supplied V Series temperature range is −28°C to +204°C (−20°F to +400°F).

Before selecting the valve, identify the working medium and its operating temperature. Also, provide the fluid concentration where relevant. These details support a review of the body, stem, packing, and other wetted components.

The applicable working pressure and pressure–temperature limits require model-specific confirmation. Therefore, include your normal and maximum operating conditions when requesting the technical specification.

Questions to Resolve During Equipment Design

Does the listed orifice establish the valve’s flow capacity?

The 0.25-inch orifice is a dimensional reference. It does not, by itself, establish flow performance under your operating conditions. Provide the required flow, medium, and pressure conditions when requesting performance information.

What should be checked for installation?

Review the mating connections, valve dimensions, handle access, and space needed for service. Use the dimensional drawing to confirm how the valve fits within the assembly.

Can it replace an existing 3/8-inch valve?

Connection size is one selection factor. Also compare pressure capability, materials, temperature limits, dimensions, and the required operating function before confirming a replacement.

Purchasing for OEM Builds and Repeat Orders

For a new equipment project, include HVNF6-15K in the bill of materials and link it to the approved drawing. Record the agreed connection details, material requirements, and operating conditions.

For repeat orders, reference the confirmed configuration and identify any changes in service. In addition, state the quantity, delivery schedule, and required documentation.

If your project requires material records, inspection documents, or specific packaging, list those items during quotation. This helps define the supply scope before the purchase order is issued.
