Parker 7321GBN88N00 Solenoid Valve 1-1/2 in Normally Closed

Product Description

The PARKER 7321GBN88N00 is a normally closed solenoid valve designed for fluid control applications requiring a 1-1/2 inch port. In its unactuated state, the valve remains closed and requires an integrated coil to complete the assembly and function. The brass body construction provides solid corrosion resistance for a range of compatible media, while the NBR seal material handles typical petroleum-based and water-service fluids. With a Cv factor of 29.0 and an orifice size of 1-9/16 inches, this valve delivers capable flow capacity for mid- to large-diameter pipe runs. A licensed technician or journeyman pipefitter typically selects this valve for process, HVAC, or industrial fluid systems.

This valve is suited for commercial and industrial installations where a normally closed, de-energized-safe configuration is required. It is appropriate for liquid or compatible gas service within the rated operating parameters, including a minimum operating pressure differential of 5 psi and a maximum temperature of 185 degrees F. The integrated-coil requirement means the coil must be sourced and matched separately before the valve is functional. This configuration is common in automated control panels, building automation systems, and process piping applications.

Key Features

• Normally closed (NC) unactuated state — safe de-energized position for most process applications
• 1-1/2 inch port size for mid- to large-diameter pipe runs
• Cv factor of 29.0 for reliable flow capacity
• Brass body construction for corrosion resistance across a range of compatible media
• NBR seal material suitable for petroleum-based fluids and general water service
• Requires a separately sourced integrated coil for complete valve operation

Compatibility

Designed as an OEM-style solenoid valve body for industrial and commercial fluid control systems requiring a normally closed, 1-1/2 inch ported brass valve with NBR seals. A compatible integrated coil must be selected and installed separately to complete this assembly.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified industrial mechanic familiar with solenoid valve assemblies. Shut off system pressure and de-energize all electrical circuits before beginning work. Verify the coil voltage and connection type match the control circuit before energizing. Follow applicable local codes and the manufacturer coil instructions for wiring and mounting orientation.
