Actuation Products Bus Products Controls & Accessories   Flow Selectors Power Units Actuation Products request more info As the local Emerson Valve Automation Partner, The Valve Automation Center is able to provide the industry’s most extensive Automation Solution. Actuators A wide selection of actuators including Rack and Pinion, Scotch Yoke, Electric, Gas/Hydraulic, Linear Piston , and Specialty to name a few. Actuation mediums include Air (Pneumatic), Hydraulic, and Electricity. Rack and Pinion Using new generation materials and designs, these actuators reliably and efficiently operate quarter-turn mechanisms including ball, butterfly and plug valves. Our rack & pinion actuators work in a broad range of applications including those with extreme temperatures, corrosion and high-cycles. Integrated control options can be readily added for improved functionality and positioning. Output torques range to 60,623 lb-in (6,850 Nm)for double-acting models and 17,333 lb-in (1,958 Nm)spring-end for spring-return models. Standard operating temperatures range from -40 ° F to +180 ° F (-40 ° C to +82 ° C) with optional high temperature trims available. Operating pressures to 120 psig (8 Bar) El-O-Matic El-O-Matic pneumatic actuators are reliable, quality products, continuously providing optimum performance under all circumstances. Hytork Aluminum rack and pinion actuators to ISO, NAMUR, VDI/VDE standards. Travel stop adjustment in both open and closed directions. Double acting and spring return. Corrosion protection both internally and externally. Bettis Representing a new generation of valve control, incorporating the latest technologies and materials available to offer a reliable, economical and long lasting product. return to top Scotch Yoke We offer a broad range of new generation pneumatic actuators with torques sufficient for virtually any application - large or small. The G-Series adds features not found anywhere else. Guaranteed output torques, water ingress protection, corrosion resistance, NAMUR standardization, close coupling, overrides and modular components are standard on most of our pneumatic actuators. Output torques to 6,000,000 lb-in (678,000 Nm)for double-acting models and 3,000,000 lb-in (339,000Nm)for spring-return models Standard operating pressures to 200 psig (14 Bar) Standard operating temperatures -20 ° F to +200 ° F (-29 ° C to +93 ° C), with optional high and low temperature trims available. Bettis Pneumatic and hydraulic actuators are ideally suited for operating ball, butterfly, plug valves, dampers and other 90 degree turn devices. return to top Electric Our electric actuators are designed to provide optimum performance under the most demanding on/off and modulating conditions. Our compact models are adaptable for trouble-free operation with small, medium or large valves. We offer maximum duty cycles to 100%, with none lower than 30%,in all available motor voltages. We have a range of hazardous and non-hazardous housings, including CSA certified enclosures, and “plug-in ” options suitable for a wide range of control functions. Output torques to 840,000 lb-in (94,920 Nm) Standard operating temperatures -40 ° F to +158 ° F (-40 ° C to +70 ° C) Smart electric models supporting bus communication protocols El-O-Matic Modular construction is used extensively in the new generation of electric actuators. Plug in modules are used for an extensive range of control options. Bettis Unique modular design to allow for simple retrofits/upgrades using over two hundred different kits including Heaters, Potentiometers, Positioners, and Transmitters and many more. Limitorque Electric and Electronic Actuators for Multi-Turn & Quarter Turn Actuators with Network Communications capabilities. No other company's actuators have logged more hours, in so many different applications, under more demanding conditions, than Limitorque's actuators. Limitorque has actuators in the field still performing after more than 60 years of service -- no other company even comes close to such an achievement. return to top Hydraulic, Linear Piston and Speciality We offer a wide variety of configurations for our hydraulically powered actuators including scotch yoke, linear and helical spline. These powerful, yet efficient actuators are used in double-acting or fail-safe spring-return designs for either onshore or offshore applications, including demanding subsea service and marine applications. Output torques to 6,000,000 lb-in (678,000 Nm)in double-acting models and 3,000,000 lb-in (339,000 Nm)in spring-return models Standard operating pressures to 5000 psig (345 Bar) Standard operating temperatures -20 ° F to +200 ° F (-29 ° C to +93 ° C) with optional high and low temperature trims available Bettis Shafer Gas/Hydraulic Our gas hydraulic actuators are found on natural gas pipelines around the world - from the Sahara to the Arctic.. Available in scotch-yoke, rotary vane or linear designs, they operate efficiently using line gas pressure. Many control options are available including linebreak detection systems, remote control and high/low shutoff. Direct gas actuators are also available Bettis Shafer Linear Piston Designed for service in safety shutdown and control applications. Dantorque General Purpose The unique design utilizes the advantages of the helical spline drive mechanism and disc spring (for spring return actuators) for a very compact design. Dantorque Subsea A highly engineered actuator based on the standard drive mechanism and disc spring packages. Shafer Rotary Vane Only one moving part allows for a 50 year design life with minimal maintenance. Double vane design will not produce any side loading forces on the valve stem or actuator bearings. The most compact and efficient actuator design available Cowan Dynamics Pneumatic & Hydraulic Cylinders Pneumatic and hydraulic cylinder actuators are ideally suited for operating any linear devices. return to top contact us on-line for a free, no obligation quotation learn what's new about this solution - click here return to welcome page
