Brass Needle Valves

Straight and angled needle valves for precision valve control

If you are looking for more precise valves for controlling your water distribution application, we have them! When you need to have a more precise resistance to flow in your non-viscous system, a needle valve just might be the solution. Designed for use in fine control of many mediums, a needle valve offers a way to control flow in very small amounts, so you get the results you need with little effort. We are pleased to offer these and many other valves for water control applications.

  • Frequently used in conjunction with coolers, instrumentation, hydraulic, and pneumatic systems
  • Compact and durable, these valves get the job done without taking up much space

Angled Brass Needle Valves

Compression x Mips Angled Needle Valves

These valves are often used for providing water to evaporative (swamp) coolers. The 1/8" mips inlet will thread directly into evaporative water cooler hose bibbs found on our hose bibb page. They can also be used to provide and control water to drinking fountains, icemakers, decorative garden fountains, patio misters, humidifiers, and many other applications requiring flow adjustment.
