Ross Controls 2781A5007 Regulating Valve Assembly

Ross Controls 2781A5007 is a 27 Series Soft Start EEZ-ON Valve designed for Safety Category 1 control, delivering gradual downstream pressurization through an adjustable internal restriction that determines the rate of pressure buildup and the time delay before full opening. This two‑way, air‑piloted valve uses 3/4 in. NPT inlet/outlet ports and a 3/4 in. NPT exhaust, with a flow coefficient (Cv) of 15.0 and a weight of approximately 2.3 kg. The model is configured as a 2/2 valve with NPT port threads, and its specifications align with the EEZ-ON soft-start functionality that Ross lists for this series. Typical applications involve ensuring controlled startup of pneumatic circuits in safety‑critical or maintenance contexts, reducing shock loads and extending actuator life by dialing in a measured pressurization profile.
