Parker 73222BN3SN00 Solenoid Valve 3/8 in Normally Open

Product Description

The PARKER 73222BN3SN00 is a normally open solenoid valve body designed for fluid control applications in HVAC, plumbing, and industrial process systems. With a 3/8 inch port, a brass body, and an NBR seal, this valve provides durable, leak-resistant service in compatible liquid and gas lines. The unit ships as a valve body only and requires a separately sourced integrated coil to complete the assembly. A minimum operating pressure differential of 5 psi is required for proper actuation. The maximum rated temperature is 185 degrees F. Licensed HVAC technicians and plumbers are the typical installers for this component.

This solenoid valve body is suited for residential and light commercial fluid control applications where a normally open configuration is required. It is commonly installed in hydronic heating systems, refrigeration circuits, water supply lines, and other piping systems that call for automated shutoff or flow control. The 3/8 inch port size fits standard pipe configurations in those systems. Because the valve is unactuated in the open state, flow passes freely until the coil energizes to close the valve. This configuration is common in safety shutoff and fail-safe flow circuits.

Key Features

• Normally open unactuated state — flow passes freely without power applied
• 3/8 inch port size for standard pipe connections
• Brass body construction for corrosion resistance in liquid and gas service
• NBR seal material compatible with a broad range of media
• Cv factor of 2.4 for predictable flow capacity sizing
• 1/2 inch orifice size
• Requires integrated coil — sold separately — for complete valve assembly

Compatibility

Designed as an OEM-style replacement or new-installation solenoid valve body for systems requiring a normally open, 3/8 inch port brass valve with NBR sealing. A compatible integrated coil must be sourced separately to complete the valve assembly.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local codes and the IPC or IFGC as appropriate. Shut off all system pressure and de-energize any related electrical circuits before beginning work. Do not install without a compatible integrated coil attached, as the valve body alone will not provide controlled actuation. Verify that the system pressure differential meets the 5 psi minimum operating requirement before commissioning.
