ASCO 18900001 Pilot Operated Solenoid Valve 145 PSI 24VDC 3.5W 50/60 Hz

ASCO 18900001 is a compact pilot‑operated, 3/2 normally closed solenoid valve engineered for compressed air and inert gas lines, rated for up to 145 psi differential pressure. It uses a 24 VDC coil with a power draw of 3.5 W, and the coil is compatible with AC input as well (AC/DC interchangeability) for 50/60 Hz operation when energized from an AC source. The valve features a CNOMO pad‑mount interface for subbase mounting and includes a manual operator as standard for local actuation. Its wetted surfaces are a glass‑filled PA body with a stainless steel core tube and stainless steel core and plugnut, while seals are nitrile (NBR); the temperature range is −10°C to +60°C. The 18900001 family is designed for easy integration into modular manifolds via joinable subbases and MA accessories. Performance notes indicate a fast response time in the millisecond range (approximately 5–10 ms at 1 bar differential). The valve is manufactured to meet applicable EU directives, and its compact, lightweight construction makes it suitable for compact automated pneumatic circuits where precise pilot control is required. This model is commonly used to sequence or control actuators in industrial pneumatic systems, offering reliable isolation and switching with a 24 VDC coil while remaining adaptable to mixed supply environments thanks to AC/DC compatibility.
