What is a Needle Valve?
A valve with a slender, tapered needle-shaped plug that mates with a conical seat. Provides precise, fine-control of small flows at high pressures. Used in instrument impulse lines, sampling systems, gauge isolation, and hydraulic circuits. Available in 1/4"–2", rated to 6,000–20,000 psi.
What is a Needle Valve used for?
Needle Valves are used in industrial piping systems for on-off isolation, flow control, or backflow prevention depending on the valve type. They are selected based on the process fluid, operating pressure and temperature, required shutoff class, and pipeline size. Vajra Industrial Solutions supplies Needle Valves certified to API 6D, ASME B16.34, and other applicable standards.
How do I select the right Needle Valve for my application?
Selecting the correct Needle Valve requires specifying: (1) nominal pipe size (NPS/DN), (2) pressure class per ASME B16.34, (3) body and trim material based on fluid compatibility and temperature, (4) end connections (flanged RF/RTJ, butt-weld, socket-weld, or threaded), (5) required certifications (API 6D, ISO 9001, fire-safe API 607).
