Parker 7121KBN1NF00 Solenoid Valve 1/8 Inch Npt

Product Description

The PARKER 7121KBN1NF00 is a direct-acting, normally closed solenoid valve designed for precise fluid or gas flow control in industrial and commercial systems. Built with a brass body and a PCTFE seal, it handles working pressures up to 365 psi and operating temperatures up to 165 degrees F. The valve accepts a wide range of coil voltages 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 to many control circuit configurations. A coil is included but an integrated coil is required for a complete, functional valve assembly. Licensed HVAC, plumbing, and industrial technicians install this valve in automated control systems.

This valve is suited for residential, commercial, and light industrial applications where a 1/8 inch NPT port is required. Its direct-acting design means it opens and closes based solely on solenoid energization, with no minimum pressure differential required for operation. Typical installations include refrigeration controls, pneumatic systems, water treatment equipment, chemical dispensing lines, and HVAC zone control circuits where reliable on/off flow switching is needed at a compact port size.

Key Features

• Direct-acting operation with zero minimum operating pressure differential
• Normally closed valve state ensures flow is blocked when de-energized
• Brass body construction for corrosion resistance in fluid and gas service
• PCTFE seal material provides compatibility with a broad range of 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
• CSA Certified, UL Listed, and NEMA 4X rated for wet and washdown environments

Compatibility

Designed as a direct-acting NPT solenoid valve replacement for systems requiring a 1/8 inch port connection. Requires an integrated coil for complete valve assembly. Verify voltage requirements and media compatibility before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with fluid or pneumatic control systems. De-energize and depressurize the system completely before removing or installing the valve. Use appropriate thread sealant on NPT connections and avoid overtightening to prevent damage to the brass body. Verify that the selected coil voltage matches the control circuit supply before energizing.
