HVNF4-15K 1/4"NPT Female Two Way Straight Needle Valve

The HVNF4-15K two-way straight needle valve combines a 316 stainless steel body, a 17-4PH stem, and bidirectional flow capability for industrial fluid circuits. Its listed connection size is 1/4 inch (6.35 mm), with an orifice diameter of 0.12 inch (3 mm).

For equipment manufacturers and purchasing teams, this model provides defined material and dimensional references for valve selection. The straight configuration can be assessed alongside the circuit layout, required operating conditions, and mating connections.

Use the HVNF4-15K catalogue number when requesting drawings, application review, or a commercial offer.

Bidirectional Flow for Circuit Layout Planning

The HVNF4-15K belongs to the V Series, whose valves support flow in either direction. This gives designers flexibility when reviewing the valve’s position within a fluid circuit.

However, installation still needs to account for connection access, handle clearance, and service space. Therefore, confirm the complete assembly layout before finalizing the equipment drawing.

Potential project evaluations include instrumentation assemblies, industrial test equipment, and fluid control panels. Suitability depends on the working medium, pressure, temperature, and required valve function.

Specified Body and Stem Materials

The valve uses two stated materials:

• Body: 316 stainless steel.

• Stem: 17-4PH stainless steel.

These material grades provide a clear basis for the purchasing specification. They also help engineering teams begin the compatibility review for the intended working medium.

Material selection should consider fluid composition, concentration, temperature, and exposure conditions. In addition, confirm the packing and other wetted components before approving the valve for a specific service.

The supplied V Series temperature range is −28°C to +204°C (−20°F to +400°F). Confirm the applicable pressure–temperature limits and packing configuration for the HVNF4-15K during quotation.

Review Connections and Operating Limits Together

Connection size is one part of valve selection. The mating thread or connection geometry must also match the approved product drawing.

Accordingly, provide the required connection standard when submitting your inquiry. Confirm the interface details before ordering fittings or releasing pipework for manufacture.

Working pressure also requires model-specific confirmation. The maximum pressure offered across a valve series does not establish the rating of every configuration. Request the HVNF4-15K working-pressure rating and its applicable temperature limits for your operating conditions.

Information for OEM and Repeat Purchasing

For a new equipment build, include HVNF4-15K in the bill of materials and link it to the approved drawing. Record the agreed materials, connection details, operating conditions, and documentation requirements.

For replacement orders, compare the existing valve’s interfaces and installation dimensions. Also, state any changes to the working fluid or operating duty.

For repeat purchases, reference the agreed configuration and identify the required quantity and delivery schedule. This helps keep the technical specification and commercial order aligned.
