Parker 7121KBN2NV00 Solenoid Valve 1/4 Inch Npt

Product Description

The PARKER 7121KBN2NV00 is a direct-acting, normally closed solenoid valve designed for precise fluid control in commercial and industrial systems. Built with a brass body and FKM fluorocarbon seal, it handles a 1/4-inch NPT port with an orifice size of 1/8 inch. The valve supports multiple voltage inputs including 12 VDC, 24 VDC, 24/60 VAC, 120 VDC, 120/60 to 110/50 VAC, and 240/60 to 220/50 VAC, making it adaptable across a wide range of control circuits. It is rated to a maximum working pressure of 125 psi and a maximum temperature of 185 degrees F. Licensed HVAC technicians, plumbers, and industrial service professionals are the primary installers of this valve.

This valve is suited for residential and light commercial HVAC, refrigeration, plumbing, and fluid-handling applications where a normally closed, direct-acting shut-off or control point is needed. Its zero-minimum operating pressure differential rating means it can open without relying on line pressure to assist actuation, which is useful in low-pressure or gravity-fed systems. The brass body and FKM seal provide compatibility with a broad range of media including water, oils, and many refrigerants. An integrated coil is included, though a separate integrated coil is required to complete the valve assembly.

Key Features

• Direct-acting operation with zero minimum operating pressure differential — functions in low-pressure and gravity-fed systems
• Normally closed unactuated state for fail-safe fluid shutoff
• Brass body construction for durability in water and fluid-control applications
• FKM fluorocarbon seal for compatibility with a wide range of media including oils and refrigerants
• Multi-voltage coil compatibility: 12 VDC, 24 VDC, 24/60 VAC, 120 VDC, 120/60 to 110/50 VAC, and 240/60 to 220/50 VAC
• CSA Certified, UL Listed, and NEMA 4X rated for use in wet and washdown environments

Compatibility

Designed as an OEM-style direct-acting solenoid valve replacement or new installation component for systems requiring a 1/4-inch NPT normally closed valve with FKM sealing and multi-voltage coil support.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial service professional. Shut off the fluid supply and de-energize all electrical circuits before beginning work. The valve requires a separately installed integrated coil for complete assembly — confirm coil voltage matches the control circuit before energizing. Follow applicable codes including IPC and NEC for fluid system and low-voltage wiring connections respectively.
