Parker's needle valves for hydrogen applications (V Series)

Parker's hydrogen V Series Needle Valves are designed for positive leak tight shut-off and regulation of fluids in process, power, and instrumentation applications.

With a wide variety of port sizes and styles, temperature capabilities ranging from -65°F to 450°F (-54°C to 232°C) and pressures to 5000 psig (345 bar), V Series Needle Valves provide the user with the utmost in flexibility when designing miniaturized tubing or piping systems.

Choice of three stem types

Differential hardness between the strain hardened stem and cold formed body threads provides improved cycle life

Choice of PTFE packing or elastomeric O-ring stem seals

Available in 316 Stainless Steel, Brass and Monel® Alloy 400 construction

Inline and angle patterns

Wide variety of US Customary and SI ports

Panel mountable

100% factory tested

Optional color coded handles

See our needle valve guide with all variants:

The V needle valves are available in different variants. For details see our product guide – here

Stem Design: 3 main variants of the V needle valve are currently being sold which are listed as below

R-Stem – All metal, blunt stem tip
N-Stem – All metal, tapered needle stem tip
K-Stem – PCTFE stem tip

Hardness: Differential hardness between the strain hardened stem and cold formed body threads provides improved cycle life.

Materials: 316 Stainless Steel, Brass and Monel® Alloy 400 construction.

Sealing: Choice of PTFE packing or elastomeric O-ring stem seals.

Performance: Pressure vs temperature gives a brief overview of different sizes of valves and its capabilities.
