Soft Seat Needle Valves - 316 SST and Alloy
Steel, Full Port
Large bore size (0.257") permits
cleanout with rod. The full-port, straight-through design reduces pressure drop
across valve, decreases turbulence, and improves flow characteristics.
Recommended for applications where bubble-tight seal is required, such as gas
transmission, metering, and flow recorders. Pressure rating to 6,000 psi.
