NAI-LOK 2 Way Stainless Steel Manifold Valve 6000psi High Pressure 1/2" Female NPT Valve Compatible with Rosemount Transmitter
The NAI-LOK 2-Way Stainless Steel Manifold Valve is specifically engineered for use with pressure transmitters such as Rosemount and other instrumentation devices. This valve enables precise isolation and venting of pressure instrumentation during calibration, maintenance, or system startup. Constructed from corrosion-resistant SS316 stainless steel and rated for up to 6000 psi, this manifold valve ensures leak-tight performance in high-pressure environments such as oil & gas, petrochemical, and power generation facilities.
Its compact, direct-mount design simplifies installation while reducing the need for multiple connections, thus minimizing potential leak paths. The valve features a soft seat or metal seat option, and is compatible with both liquid and gas media.
