compact 2/2 way normally closed control for air, water, oil, and gas. Featuring a small orifice (e.g., 1.2-4mm) for precise flow, these brass body valves operate from zero pressure. Ideal for general-purpose on/off applications, pilot control, or systems requiring fast response with low flow rates (G1/8″-G3/8″ ports).
