DK-LOK V46A Series Needle Valve, 10000 psi, 1/2" Female NPT Connections, SS316, V46A-F-8N-S
Technical overview
The DK-LOK V46A series needle valve with 1/2" Female NPT Connections is engineered for reliable throttling and shutoff up to 10000 psi at 100°F (38°C). The hex-body design provides strength in a compact footprint, while the non-rotating stem tip supports smooth operation and repeatable adjustment. Suitable for high-pressure instrument tubing and piping where stable flow control, leak-tight isolation, and SS316 compatibility are required.
Key Features
