Parker 73218BN3TN00 Solenoid Valve 3/8 Inch Npt Brass

Product Description

The PARKER 73218BN3TN00 is a direct-acting solenoid valve designed for fluid and gas control in industrial, HVAC, and process piping applications. It features a 3/8 inch NPT port with a normally closed (NC) unactuated state, meaning flow is blocked until the coil is energized. The brass body and NBR seal construction handle a broad range of compatible media including water, air, and many hydraulic fluids. The valve accepts multiple coil voltage ratings and carries CSA, UL, and NEMA 4X listings, making it suitable for both indoor and outdoor installations where moisture resistance is required. Licensed technicians and industrial maintenance professionals typically install this valve.

This valve is appropriate for residential and commercial applications including HVAC water control, pneumatic systems, irrigation, and fluid process lines. The 3/8 inch NPT connection fits standard pipe fittings commonly found in mechanical rooms, rooftop equipment, and process skids. The integrated coil design simplifies installation, though a compatible integrated coil must be verified for complete valve assembly. The Cv factor of 3.0 supports moderate flow rates through the 5/8 inch orifice at operating pressures between 5 psi and 150 psi.

Key Features

• Normally closed operation — flow blocked when de-energized, open when coil is energized
• Brass body construction for corrosion resistance in water and air service
• NBR seal material compatible with a wide range of fluid media
• Multi-voltage coil compatibility: 12 Vdc, 24 Vdc, 24/60 Vac, 120 Vdc, 120/60 to 110/50 Vac, 240/60 to 220/50 Vac
• NEMA 4X rated enclosure suitable for wet and outdoor environments
• CSA Certified and UL Listed for use in code-compliant installations

Compatibility

Designed as an OEM-style replacement or new-installation solenoid valve for 3/8 inch NPT piping systems requiring a normally closed, brass-body valve with NBR seals. Requires a compatible integrated coil for complete valve assembly.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial mechanic. De-energize the circuit and shut off the fluid supply before beginning installation or service. Verify coil voltage matches the available supply voltage before energizing. Follow applicable codes including IFGC or IPC for gas and water piping, and NEC Article 430 or applicable sections for the electrical connection.
