SMC NAV4000-N04-5DZ Solenoid Valve Soft Start

SMC NAV4000-N04-5DZ Soft Start is a direct-operated, two-position solenoid valve that provides a soft-start function for pneumatic circuits. It is driven by a 24 VDC coil and features a 1/2 in port with an operating pressure range of 0.2 to 1 MPa (about 29 to 145 psi). The valve delivers a Cv flow rate of 3.6/4.49 and is designed to gradually ramp air to downstream components, reducing pressure surges during startup. An indicator light and a surge voltage suppressor are included to provide status feedback and electrical protection, and the NAV4000-series model offers a compact form factor suitable for installations where space is at a premium. This 2-position valve enables straightforward control of airflow, making it a practical choice for automated pneumatic systems that require controlled actuation of downstream devices while mitigating startup shocks and noise. With its 1/2 in nominal port and soft-start capability, the NAV4000-N04-5DZ is well-suited for applications that demand reliable, gradual pressurization of pneumatic lines within compact control panels or automation lines.
