Parker 7321GBN76N00 Solenoid Valve 1-1/4 in Brass Nbr

Product Description

The PARKER 7321GBN76N00 is a normally closed solenoid valve designed for fluid control applications in industrial and mechanical systems. With a 1-1/4 inch port size and a brass body construction, it provides durable, corrosion-resistant performance across a range of compatible media. The valve features an NBR (Buna-N) seal and a 1-1/8 inch orifice, delivering a Cv factor of 19.3 for reliable flow capacity. Note that this valve requires a separately sourced integrated coil for complete, functional operation. Licensed HVAC, plumbing, and industrial mechanical technicians typically specify and install this component.

This solenoid valve is suited for use in residential and light commercial fluid control systems where a normally closed, de-energized shutoff is required. Typical applications include water, air, and compatible fluid service lines where the valve remains closed until electrical actuation is applied. A minimum operating pressure differential of 5 psi is required for proper valve actuation. The brass body and NBR seal make it appropriate for use with water, air, and many petroleum-based fluids within rated temperature limits. An integrated coil must be specified and ordered separately to complete the valve assembly before installation.

Key Features

• Normally closed (NC) unactuated state for fail-safe shutoff when de-energized
• 1-1/4 inch port size with 1-1/8 inch orifice for high-flow capacity
• Cv factor of 19.3 for predictable flow performance in system design
• Brass body construction for corrosion resistance and durability
• NBR seal material compatible with water, air, and many petroleum-based fluids
• Requires integrated coil — sold separately — for complete valve operation

Compatibility

Designed as an OEM-style replacement or new-installation solenoid valve for fluid control systems requiring a 1-1/4 inch normally closed brass body valve with NBR sealing. An integrated coil must be sourced separately for complete valve assembly.

Installation Notes

Installation should be performed by a licensed plumber, mechanical contractor, or qualified industrial technician following applicable local codes and IPC guidelines. Shut off the fluid supply and relieve system pressure completely before removing or installing the valve. Do not energize the valve without the integrated coil properly mounted and wired per the coil manufacturer specifications. Verify that system pressure differential meets the 5 psi minimum requirement for reliable valve actuation before commissioning.
