Parker B5G1BCNXXC Solenoid Valve 1/4 Inch Npt

Product Description

The PARKER B5G1BCNXXC is a normally closed solenoid valve designed for fluid and gas control in industrial and commercial systems. With a 1/4 inch NPT port and an aluminum body fitted with a Buna-N seal, this valve is built for reliable, repeatable shutoff service. It operates within a working pressure range of 20 to 145 psi and carries a flow coefficient (Cv) of 1.4, making it suited for moderate-flow applications where precise on/off control is required. A licensed technician or qualified pipefitter typically installs this valve in process lines, HVAC auxiliary circuits, or fluid handling systems.

This valve fits residential and light commercial applications where a compact, normally closed solenoid valve is needed in a 1/4 inch NPT line. Typical installations include refrigeration solenoid circuits, pneumatic control lines, water or air service runs, and similar piping systems that require electrically actuated shutoff. The aluminum body keeps weight low while maintaining structural integrity across the rated pressure and temperature range. Note that the solenoid coil is not included and must be sourced separately to complete the assembly.

Key Features

• Normally closed configuration holds the valve shut when de-energized, providing fail-safe shutoff
• 1/4 inch NPT port for direct in-line pipe installation
• Aluminum body reduces overall assembly weight
• Buna-N seal material provides compatibility with water, air, and many petroleum-based fluids
• Cv factor of 1.4 supports moderate flow rates within the rated pressure band
• Maximum working pressure of 145 psi with a minimum inlet requirement of 20 psi

Compatibility

Designed as an OEM-style replacement or new-installation solenoid valve for 1/4 inch NPT normally closed valve applications operating within 20 to 145 psi. Solenoid coil is not included and must be ordered separately to actuate this valve.

Installation Notes

Installation should be performed by a licensed pipefitter, HVAC technician, or qualified trades professional following applicable local codes and IFGC or IPC guidelines where relevant. Isolate and depressurize the line completely before beginning any work, and verify system pressure falls within the 20 to 145 psi operating range before returning to service. Do not exceed the 120 degrees F maximum temperature rating. Because the solenoid coil ships separately, confirm coil voltage and electrical compatibility before energizing the valve.
