Ross Controls 2775A5903 Solenoid Pneumatic Directional Control Valve

Ross Controls 2775A5903 is a solenoid-pilot inline directional control valve from the 27 Series, designed to route compressed air between ports in compact pneumatic circuits in response to electrical actuation of the solenoid. The unit is specified as a 29-123 PSI valve, with the Mfr part number 2775A5903 appearing in retailer listings as a discontinued Ross component, signaling limited current availability in some markets. In the 27 Series, solenoid-pilot valves are offered in inline configurations across multiple body sizes and port options, and the exact port size, valve function (for example 3/2 or 4/2 configurations), and electrical voltage for this model are defined by the complete model code. Inline mounting and compact form factor make this valve suitable for control panels and machinery frames where space is at a premium, with duties including directing air to actuators such as cylinders in automation systems within the specified pressure range. Because the model code determines the electrical and port details, customers should refer to official Ross specifications or product literature to confirm compatibility with a given application.
