Parker B814BCNXXA Solenoid Valve 3/4 Inch Npt

Product Description

The PARKER B814BCNXXA is a 3/4 inch NPT solenoid valve configured in a normally open state through ports 1 and 2. It features an aluminum body and Buna-N seals, making it suited for a range of fluid control applications in HVAC, plumbing, and industrial process systems. The valve operates within a working pressure range of 35 to 145 psi and carries a Cv factor of 7.0, indicating strong flow capacity for its port size. A coil is included with the valve. Licensed trades use this valve in automated fluid shutoff and control circuits where a de-energized open state is required for system safety or process design.

This valve is well suited for residential and light commercial HVAC systems, hydronic piping, and general plumbing applications requiring automated flow control. The normally open configuration is commonly specified in systems where fluid flow must continue during a power loss or control signal interruption. It installs in line with NPT-threaded pipe runs and is compatible with standard 3/4 inch pipe fittings. Plumbers, pipefitters, and HVAC technicians are the primary installers of this type of valve in mechanical systems.

Key Features

• Normally open through ports 1 and 2 for fail-open flow control
• 3/4 inch NPT port size fits standard pipe thread connections
• Aluminum body offers a lightweight, corrosion-resistant construction
• Buna-N seals provide compatibility with common water and oil-based media
• Cv factor of 7.0 supports adequate flow rates at rated pressures
• Operating pressure range of 35 to 145 psi suits most commercial and residential applications

Compatibility

Designed as an OEM-style replacement or new-installation solenoid valve for systems requiring a 3/4 inch NPT normally open valve with aluminum body construction and Buna-N seals.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local mechanical codes and ASME piping standards. Shut off the fluid supply and depressurize the line completely before removing any existing valve or making new connections. Note that solenoid coils are not included and must be sourced separately to complete the assembly. Verify that the media, temperature range, and operating pressure of the system fall within the rated limits of this valve before placing it in service.
