Transmitter Isolation Ball Valves — faster, stronger, cleaner.

The best isolation valves available, built for one job. A patented 3″ full-port ball gives your transmitter a clean, unobstructed view of the process — with calibrate-in-place purge ports and a quarter-turn, bubble-tight shutoff.

The 305 / 105 / 115 Series

Six figures. One purpose.

Every figure mounts to both standard ANSI 150# flanges and existing knife-gate patterns, so most installs are a straight swap. Choose your port size, purge configuration, and material — from 316 stainless to all Grade-5 titanium.
