Needle Valves

Needle Valves support flow measurement, switching, control, or installation work in liquid, gas, air, water, and process systems. Products in this category span PTFE needle valves, corrosion-resistant valves, high-purity valves, barstock needle valves, 316 stainless steel bodies, brass needle valves, hot-forged brass bodies, and fine manual flow control valves.

Applications include laboratory gas flow, chemical feed, high-purity fluid handling, sample lines, analytical equipment, purge lines, test stands, and industrial systems that need gradual manual adjustment rather than simple shutoff. Products represented in the source data include Omega Engineering and Dwyer Instruments.

Applications include:

• Manually regulate low or moderate flow
• Control corrosive gases and liquids with compatible materials
• Use high-purity or chemical-resistant construction
• Set purge, sample, or metering flows
• Support laboratory and industrial flow control
