Parker 7121KBN2NF00 Solenoid Valve 1/4 in Normally Closed

Product Description

The PARKER 7121KBN2NF00 is a normally closed solenoid valve body designed for precise fluid control in industrial and commercial fluid systems. Built with a brass body and PCTFE seal material, this valve body handles demanding media compatibility requirements where standard elastomers fall short. It features a 1/8-inch orifice and a Cv factor of 0.31, making it suited for low-flow applications. Note that this part requires a separately sourced integrated coil to function as a complete valve assembly. Licensed plumbers, pipefitters, and fluid system technicians are the typical installers for this type of component.

This valve body is appropriate for use in refrigeration, pneumatic, liquid, and process fluid systems requiring a normally closed, de-energized-closed configuration. With a minimum operating pressure differential of 0 psi, it can open under zero differential pressure conditions when paired with the correct coil. The brass body and PCTFE seal make it a fit for applications involving aggressive or specialty media where standard Buna-N or EPDM seals would degrade. The 1/4-inch port size suits compact piping runs in light commercial and industrial installations.

Key Features

• Normally closed valve body — de-energizes to the closed position for fail-safe fluid shutoff
• Brass body construction for corrosion resistance in a wide range of fluid media
• PCTFE seal material for compatibility with aggressive or specialty process fluids
• 1/8-inch orifice with a Cv factor of 0.31 for controlled low-flow applications
• Zero minimum operating pressure differential — suitable for gravity-fed or low-pressure systems
• Requires a separately sourced integrated coil to complete the valve assembly

Compatibility

Designed as an OEM-style solenoid valve body replacement for industrial and commercial fluid control systems using 1/4-inch port connections and requiring PCTFE sealing. A compatible integrated coil must be sourced separately to complete the assembly.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified fluid systems technician. Shut off all fluid supply and depressurize the line before beginning installation or removal. Verify coil voltage and electrical ratings before connecting the integrated coil, and follow applicable local codes and NEC requirements for wiring. Do not overtighten fittings into the brass body ports, as brass threads can be damaged by excessive torque.
