A-T Controls´ TRIAC F91 valve/actuator packages are ideal for corrosive and caustic environments, featuring rugged construction, solid unibody and patented pyramidal stem packing, while regular-port design minimizes cost and reduces operating torque. To save installation time and work, the F91 flanged-ball valves feature patented direct-mount actuator pad and can be ordered pre-assembled with robust, weather-proof WE electric actuator. They comply with the NACE MRO175 standard for corrosion resistance and are certified to API 607-4th edition. F91 valves are available in a wide range of seat materials and several hard-face and metal-metal options. They feature an anti-static device and can be specified as traceable.
A patented automation pad allows direct mounting of ISO5211-compliant actuators to eliminate the cost and fabrication of special couplings or brackets. WE Series electric actuators provide matching ruggedness and corrosion-resistance, featuring weather-proof, die-cast aluminum housings. Rugged construction provides water- and explosion-proof security. An anti-condensation heater with thermostat comes standard. The F91 valves come in manual as well as automated versions. Beside packaging with WE electric actuators, they can be ordered pre-assembled with pneumatic actuators in spring-return or double-acting configuration.
