Parker B854BCNXXA Solenoid Valve 3/4 Inch Npt

Product Description

The PARKER B854BCNXXA is a 3/4 inch NPT solenoid valve designed for fluid control applications in industrial and commercial systems. In its unactuated state, all ports are blocked, making it suitable for systems that require a fail-closed or no-flow condition when de-energized. The valve body is constructed from aluminum, and the seals are Buna-N, supporting a working pressure range of 45 to 145 psi. It carries a Cv factor of 7.0, indicating solid flow capacity for its port size. Licensed plumbers, pipefitters, and industrial service technicians typically specify and install this valve in process control, HVAC auxiliary, and fluid distribution systems.

This valve is suited for residential and light commercial fluid control applications where a 3/4 inch NPT connection is required. It fits into systems that need positive shutoff at rest, such as water treatment, irrigation control, compressed air circuits, and HVAC fluid lines. Maximum operating temperature is 120 degrees F. Note that solenoid coils are not included with this valve body and must be sourced separately. Verify coil voltage and electrical class compatibility before ordering.

Key Features

• All-ports-blocked unactuated state provides fail-closed operation with no flow when de-energized
• 3/4 inch NPT port size fits standard pipe fittings used in plumbing and fluid control systems
• Aluminum body offers lightweight construction suited for moderate-pressure applications
• Buna-N seals provide compatibility with water, air, and many common hydraulic fluids
• Cv factor of 7.0 supports adequate flow capacity for 3/4 inch line applications
• Working pressure range of 45 to 145 psi covers a broad range of system operating conditions

Compatibility

Designed as an OEM-style replacement or new-installation solenoid valve for 3/4 inch NPT fluid control systems operating within 45 to 145 psi and up to 120 degrees F. Solenoid coils are not included and must be selected and ordered separately to match the required coil voltage and configuration.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local codes and the system manufacturer's guidelines. Shut off fluid supply and relieve system pressure completely before removing or installing the valve. Apply thread sealant to NPT connections per standard practice and avoid overtightening, which can crack the aluminum body. Confirm coil voltage and electrical connections comply with NEC requirements before energizing the valve.
