Asco 8324021MO 3-way Solenoid Valve 1/4 Inch Npt 0-50 Psi

Product Description

The ASCO 8324021MO AC120/60,110/50D is a 3-way, manually operated solenoid valve designed for controlling air and inert gas flow in pneumatic and process systems. Built with an aluminum body and a 1/4-inch NPT connection, this valve operates across a pressure range of 0 to 50 psi and accepts dual-voltage supply at 120/60 VAC or 110/50 VAC. The 3-way configuration allows the valve to shift flow between two outlet paths, making it well suited for actuator control, pilot circuits, and similar directional flow applications. Licensed HVAC technicians, industrial service professionals, and mechanical contractors are the typical installers of this valve type.

This valve is rated for use with air and inert gas media, and carries a NEMA 1 enclosure rating, making it appropriate for indoor installations protected from the elements. It is commonly used in light commercial and industrial pneumatic control systems, including actuator pilot circuits, instrument air lines, and process gas routing applications where a compact 1/4-inch NPT fitting is required. The manual-operation design means the valve can be actuated without relying solely on electrical signal, which is useful in applications requiring manual override capability.

Key Features

• 3-way valve configuration for directional flow control in pneumatic circuits
• Dual-voltage rated: 120/60 VAC and 110/50 VAC for flexible installation across North American and international systems
• 1/4-inch NPT connection fits standard pipe and fitting sizes common in instrument air and gas pilot lines
• Aluminum body construction for lightweight service in low-corrosion air and inert gas environments
• Manually operated function provides local override capability without electrical actuation
• NEMA 1 enclosure rating suitable for general indoor use
• Pressure range of 0 to 50 psi covers typical low-pressure pneumatic control circuit requirements

Compatibility

Designed as an OEM-style replacement or new-installation 3-way solenoid valve for indoor pneumatic control systems using air or inert gas media with 1/4-inch NPT pipe connections and operating at pressures up to 50 psi.

Installation Notes

Installation should be performed by a qualified mechanical or instrumentation technician familiar with pneumatic control systems and applicable codes. De-energize the circuit and relieve all system pressure before removing or installing any solenoid valve. Verify pipe thread integrity and use appropriate thread sealant rated for air and gas service. Confirm supply voltage matches the 120/60 VAC or 110/50 VAC rating before energizing the valve.
