Ross Valve W1123A2001 Pneumatic Pressure Regulator

ROSS Controls 1123A2001 Palm Button Valve is a compact 3/2 pneumatic valve with spring-return action, designed for handheld operation in automation systems. It uses 1/4" NPT ports (P, A, R) for straightforward integration into standard pneumatic lines, and is rated for an operating pressure range of 0.3 to 10 bar (5 to 150 psi). This model belongs to the 11 Series Palm Button valves, offering momentary actuation to connect the P port to the A port and vent exhaust through the R port when the button is released. It is a valve, not a regulator, intended to direct airflow rather than set system pressure, making it suitable for manual control tasks in compact pneumatic circuits where tactile feedback is important. Spring-return ensures the valve returns to its default position after actuation, enabling repeatable control in handheld or panel-mounted installations.
