A-T Controls” TRIAC Series LB ball valves are designed for advanced anti-corrosion chemical processing. The valves feature a full PFA lining and electropolished 304 stainless steel or epoxy-coated WCB carbon steel bodies. High-purity PFA lines the body and seamless ball at three millimeters and greater thickness. The liner is secured into the valve body with the “KPF” interlock system tested at 20,000 VDC and vacuum-rated at one MBAR. More durable than PTFE, the PFA provides extremely low gas permeability and delivers high performance in critical service. Available in 1/2″ to four-inch sizes, the 150-pound flanged split-body valves feature a self-adjusting “V” ring packaging. Full-port valve design minimizes operating torque, while two-piece ball-and-stem design reduces side loading and extends stem and packing life. The value-engineered designs feature standard electropolishing on stainless body valves and offer economical pre-assembly with actuator. A complete range of pneumatic double-acting, pneumatic spring-return, or electric actuators covers the spectrum of automation needs.
