A-T Controls TRIAC

TRIAC ball valves, butterfly valves, and a complete line of actuation — engineered for hydrocarbons, fire-safe service, and pipeline isolation.

About the Manufacturer

Three Categories. One Manufacturer. Complete Solutions.

A-T Controls is one of the leading suppliers of industrial valves and actuators in North America. Their TRIAC product line — best known for trunnion-mounted ball valves rated to API 6D for pipeline service — covers the full spectrum from utility ball valves to high-pressure forged-body designs.

What sets A-T Controls apart is the integration of three product families under one engineering culture: TRIAC ball valves, a complete butterfly valve line (resilient-seated, high-performance, and triple-offset), and a full range of pneumatic, electric, and hydraulic actuators. That means you can spec a complete valve-actuator package with one engineering review and one purchase order.

"From utility ball valves to API 6D pipeline service to fully automated valve-actuator packages — under one roof, with one engineering culture."

Miller Valve has been an A-T Controls partner for years, serving customers across oil & gas, chemical, power generation, marine, and industrial water. Stocking inventory, same-day quotes, and engineering support for every product in their catalog — from a utility ball valve to a fully-actuated pipeline isolation valve.
