ROSS CONTROLS 1123A2001 Pneumatic Pushbutton

ROSS Controls 1123A2001 is a 3/2 palm-button pneumatic valve with spring-return action, intended for manual control of small pneumatic circuits in panels and operator stations. It is part of the 11/12 Series Palm & Push Button Valves and uses a 1/4" NPT port size, configured (normally closed) for typical pushbutton operation. The valve features a Cv of 0.5 and weighs about 1.0 lb (0.5 kg), making it suitable for compact installations where tactile local actuation is needed. Pressing the palm button shifts the internal spool to create the actuated circuit, and releasing the button returns the valve to its default state, providing a simple, mechanical means to pilot downstream pneumatic devices without electrical wiring. This model is commonly used to manually pilot secondary valves or control small-diameter air lines in industrial automation, ensuring quick, localized control within control panels and operator stations.
