Parker 73212BN52N00 Solenoid Valve 3/4 in Npt Brass

Product Description

The PARKER 73212BN52N00 is a normally closed, direct-acting solenoid valve designed for fluid control in industrial and commercial piping systems. Built with a brass body and NBR seal, it handles a wide range of compatible media across liquid and gas applications. The valve accepts multiple voltage configurations — 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 varied control circuits. It carries a 3/4-inch NPT port with a 3/4-inch orifice and a Cv factor of 7.3, supporting flow rates suited to mid-size process lines. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this valve type.

This valve is suited for residential and light commercial fluid control applications where a normally closed, de-energized-shut configuration is required. Typical install scenarios include water supply shutoff, irrigation control, HVAC hydronic systems, and compressed air lines. The broad voltage compatibility allows the valve to integrate with 24-volt low-voltage controls common in HVAC systems as well as 120 Vac and 240 Vac industrial control panels. The minimum operating pressure differential of 5 psi and maximum working pressure of 300 psi define the functional envelope for system design.

Key Features

• Normally closed (NC) configuration — valve shuts off when de-energized for fail-safe operation
• Brass body construction provides corrosion resistance in water and compatible fluid service
• NBR seal material suitable for water, air, and many petroleum-based fluids
• Wide 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
• Cv factor of 7.3 and 3/4-inch orifice support adequate flow capacity for mid-size piping runs
• CSA Certified, UL Listed, and NEMA 4X rated for use in wet or washdown environments

Compatibility

Designed as an OEM-style replacement or new-installation solenoid valve for 3/4-inch NPT piping systems requiring normally closed electric shutoff control. Note that this valve requires an integrated coil for complete valve assembly — confirm coil selection matches the intended supply voltage before ordering.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Shut off all fluid supply and depressurize the line before removing or installing the valve. Electrical connections must comply with applicable NEC requirements for control voltage wiring, and the enclosure rating of the coil assembly should match the installation environment. Do not exceed the 300 psi maximum working pressure or the 185 degrees F maximum temperature rating in service.
