SMC NAVA4000-N04 AN40-N04 Air Pilot Valve Gauge And Silencer

SMC NAVA4000-N04 is an air pilot valve with a built‑in pressure gauge and silencer, delivering integrated monitoring and quieter exhaust in a single assembly. The included silencer is the AN40-N04, a compact resin silencer with a 1/2 NPT external thread designed for exhaust ports on pneumatic circuits and capable of reducing noise to about 30 dB(A). AN40-N04 silencers are cataloged by SMC for use with 1/2 inch NPT ports and are listed among standard silencer options for the VBA/VBAT family components, making it straightforward to pair with the NAVA4000 valve in modular automation setups. This combination is commonly used in automation applications where reliable air pilot control is required and quieter exhaust is desirable in environments such as conveyors or packaging lines.
