Ross Controls 2774B4001 Solenoid Directional Valve

Ross Controls 2774B4001Z is a Classic 27 Series inline, solenoid-pilot directional valve engineered for pneumatic control in automation systems. This 3/2, single-solenoid valve is normally open with a spring return, meaning it returns to the default position when de-energized, and is driven by an AC coil rated for 110–120 V, 50/60 Hz (coil code Z). Inrush and holding power for the AC coil are typically about 87 VA and 30 VA, respectively, making it compatible with standard AC power sources. The valve body is cast aluminum, the poppet is constructed from acetal with stainless steel support, and seals are Buna-N, delivering durable cycling in industrial environments. Operating pressure for this family is specified from 15 to 150 psig, accommodating a wide range of actuator and cylinder applications. For reliability in continuous use, Ross recommends vertical mounting with the solenoid oriented upward to aid condensate drainage. The 2774B4001Z belongs to the 27 Series’ family of solenoid-pilot valves, known for compact inline integration, robust construction, and dependable performance in automated pneumatic circuits.
