ROTEX offers a range of Solenoid Valves and Air Operated Valves used for handling almost any fluid with various of temperature, pressure or vacuum for use in Control and Automation applications.
ROTEX limit switches are designed to last and meet your required service conditions. Both the weather proof and explosion proof switches feature an aluminum die cast enclosure that is powder coated for superior corrosion resistance resulting in a weather proof enclosure to IP67. Stainless steel enclosures are available, also confirming to IP67.
Proper Actuator to Valve Torque SizingA quarter turn pneumatic actuator, wether direct acting or spring return, has a given output torque based upon the air supply pressure provided. This output torque can be fairly linear, or very non-linear depending on the sty…Read More
Defining a "Quick Acting" Pneumatic ActuatorThe desired speed of the pneumatic actuator opening or closing is a consideration of the application itself. For applications where an open valve may feed a fire, or overfill a tank, quick closing is required. Conversely, the…Read More
What is a Rack & Pinion Actuator?According to Wikipedia, "A rack and pinion is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion. A circular gear called "the pinion" engages teeth on a linear "gear" b…Read More
Actuators 101: Quarter-turn Pneumatic Actuator TypesPneumatic valve actuators come in two basic types: rack & pinion and scotch-yoke. Both style actuators provide 90 degree rotational torque to drive a quarter-turn valve (ball, plug, butterfly) open or closed.The scotch-yo…Read More
Industrial Valve Limit SwitchesIn industrial valve terms, a limit switch is a device containing one or more magnetic or electrical switches, operated by the rotational or linear movement of the valve actuator. They are used to show the open or closed posit…Read More
