HVNF2-15K-DO-NC Pneumatic Control Needle Valve

The HVNF2-15K-DO-NC Pneumatic Control Needle Valve allows for remote on-off operation via a diaphragm pneumatic actuator. Its normally closed, air-to-open design makes it ideal for equipment setups that require pneumatic switching of process lines.

The provided specifications list a maximum operating pressure of 15,000 psi (1,035 bar), pneumatic drive pressure of 45 psi (3.10 bar), and a 1/8 inch tube outer diameter.

For OEM engineers and procurement teams, the complete model designation uniquely identifies the valve and actuator configuration for quotation, drawing review, and component selection.

Remote Switching via Diaphragm Pneumatic Actuator

The diaphragm actuator operates the needle valve using control air. This allows the valve to receive an open command from a remote pneumatic control system.

For equipment assembly, define the required operating sequence and the valve's role within the circuit. Also, specify how the pneumatic command will be supplied and controlled.

The normally closed design is a key selection detail. Include it in the circuit diagram and procurement description to ensure the quoted valve matches the intended control function.

HVNF2-15K-DO-NC Technical Data

Process pressure and pneumatic drive pressure apply to different parts of the valve assembly. Please confirm the required actuation conditions at the intended process pressure during the technical review.

Matching the Valve to the Process Connection

The catalog specifies a 1/8 inch tube outer diameter. Confirm the complete connection geometry and mating fitting specifications against the product drawing before ordering piping or adapters.

Next, review the working medium, operating temperature, and required flow rate. These details support the selection of wetted parts materials, seals, and valve configurations.

If the valve is replacing an existing component, provide its model number, connection drawing, and installation dimensions. This helps identify the mechanical and operational requirements for the replacement.

When comparing connection and operational options, refer to our range of needle valves.

Defining the Pneumatic Control Interface

Include the available control air pressure and the expected switching frequency in your inquiry. If the opening or closing time is critical to the machine cycle, please also specify the required response time.

Additionally, identify any associated components required within the supply scope, such as pneumatic switching valves, air preparation equipment, tubing, or fittings. Confirm which items are included in the quotation.

For installation, please request the assembly dimensions and ensure access to the actuator's pneumatic connection, process fittings, and service points.

Procurement Information for OEM and Repeat Orders
