Shopping for solutions

Why would a salesperson want to see me?
Today’s best way to source a valve solution — like so much else in the industrial world — leverages the supply-chain coordination and communication advances following from on-going computerization, digitization and what industrial research analysts like to call “the internet of things.”

Ask the Valve Expert: New valve automation technology

Benefits follow use of larger-series pneumatic rack-and-pinion actuators

The extended size range of today’s pneumatic rack-and-pinion valve actuators that can now automate up to 32-inch butterfly valves, and up to 14-inch ball valves, offers an advantageous alternative to the large-size, scotch-yoke actuator mechanism that has been popular in industry for quite some time.

Easy maintenance characteristic of two-piece, reduced-bore split-body ball valve

As an alternative to one-piece ball valve body designs, a new split-body valve series with a two-piece bolted-body design meets ANSI take-out dimensions for either a long full port or short reduced port pattern.
