Honeywell VBN2BJPL3000 Control Valve 7.4 Cv 3/4 in Npt

Product Description

The HONEYWELL VBN2BJPL3000 is a 2-way characterized control valve designed for modulating hydronic flow control in commercial and residential HVAC systems. It features a 3/4 inch NPT connection, a flow coefficient of 7.4 Cv, and brass trim construction. The valve pairs with a fail-in-place modulating actuator operating at 24 volts AC, making it suitable for variable flow applications where maintaining last position on power loss is a system requirement. HVAC technicians and mechanical contractors install this valve as part of fan coil, air handling, and terminal unit piping assemblies.

This valve assembly is intended for hydronic heating and cooling applications in light commercial and residential systems. It accepts an analog control signal for precise modulating operation, allowing the building automation or zone control system to regulate flow continuously across the full stroke range. The 3/4 inch NPT connections allow direct installation into standard threaded pipe assemblies without special adapters.

Key Features

• 2-way flow pattern for standard supply or return line installation
• 7.4 Cv flow coefficient for accurate hydronic flow sizing
• 3/4 inch NPT threaded connections for direct pipe installation
• Brass trim construction for durability in hydronic service
• Modulating analog control signal input for variable flow regulation
• Fail-in-place actuator maintains last valve position on loss of power or signal
• 24 volt AC actuator power for compatibility with standard low-voltage controls

Compatibility

Designed as an OEM-style characterized control valve assembly for use in modulating hydronic HVAC applications requiring 3/4 inch NPT connections and 7.4 Cv flow capacity.

Installation Notes

Installation should be performed by a licensed HVAC technician or mechanical contractor familiar with hydronic piping systems. Isolate and depressurize the hydronic circuit and shut off all associated electrical power before beginning work. Ensure pipe threads are clean and properly sealed with appropriate thread sealant rated for hydronic service. Verify actuator wiring and control signal connections comply with the system controller manufacturer specifications and applicable local codes.
