SMC NAV4000-N04-5DZ Pneumatic Directional Control Valve

SMC NAV4000-N04-5DZ is a direct-operated soft-start up valve in the NAV4000 series, engineered to provide controlled ramping on pneumatic actuation and reduce shock loads in compact circuits. It has a 1/2 in nominal port (NPT) and operates over a 0.2 to 1 MPa range, with a flow coefficient of 3.6/4.49 Cv for predictable response across load conditions, and it provides two positions for reliable on/off control. The N04-5DZ variant includes an indicator light and surge-voltage suppressor for DC operation, and is typically powered by 24 VDC, enabling easy integration with standard automation panels. Ideal for compact automation tasks needing soft-start control—such as cylinder start-up, sequencing, or gentle actuation—in tight spaces where reliability and diagnostic visibility matter.
