1/2 in. Stainless Steel Male NPT x Female NPT Mini Ball Valve
Overview
The Midland Industries 46933SS is a 1/2 in. mini ball valve machined from 316 stainless steel (CF8M) with Male NPT x Female NPT (MPT x FPT) end connections. It is rated to 400 psi across -14 to 300°F, with a PTFE seat and PTFE seals for corrosion resistance and clean media. A quarter-turn handle gives positive shutoff for instrumentation, sampling, compressed-air, and corrosive-service lines.
