The 3/8 in. x 1/4 in. Brass Needle Valve, 90-Degree, Compression x Male NPT is a brass needle valve with a 90° elbow body for tight-space installations where a straight valve body won't fit and compression × male NPT connections. Needle valves provide precise, adjustable flow metering by advancing a tapered needle into or out of a matching seat — allowing smooth control from fully closed to fully open.
Technical Specifications
| Specification | Value |
|---|---|
| Body Material | Brass (dezincification-resistant) |

Key Features
- Tapered needle provides fine flow resolution — far more precise than ball or gate valves
- 2,000 WOG brass body rated for high-pressure instrument and gauge service
- PTFE stem packing — low breakout torque and leak-free stem seal
- Not designed for full-bore high-Cv flow — use ball valves for on/off shutoff
- Standard for pressure gauge root valves, pressure transmitter isolation, and sample point shutoff
- 90° elbow body for panel-mount and tight-space instrumentation applications
Common Applications
Pressure gauge root valves, pressure transmitter isolation, chemical injection metering, instrument air supply control, hydraulic circuit balancing, sample point shutoff, and any application requiring precise, adjustable flow control at high pressure.
