Description
The Johnson Controls VG7251LT is a precision-engineered 2-way, normally open globe valve designed for reliable flow control in commercial HVAC hydronic systems. Built with a cast bronze body and brass trim, this valve delivers long-lasting durability and corrosion resistance in demanding heating and cooling applications.
Key Features
- 2-way, normally open (NO) configuration for fail-safe operation
- 3/4″ union globe end connections for easy installation and removal
- 7.3 Cv flow coefficient for accurate system balancing
- Equal percentage flow characteristic for precise, stable modulating control
- Cast bronze body with brass trim for superior corrosion resistance
- Standard threaded stem design for compatibility with a wide range of actuators
- Push-down-to-close (PDC) stem action for predictable valve response
Construction & Design
The VG7251LT features a rugged cast bronze body that withstands the rigors of hydronic heating and cooling circuits. Union globe end connections simplify field installation and in-line servicing without disturbing adjacent piping. The standard threaded stem is compatible with Johnson Controls VA and VB series actuators, making this valve a versatile choice for new construction and retrofit projects alike.
Flow Characteristics
With an equal percentage flow characteristic and a 7.3 Cv rating, the VG7251LT provides smooth, proportional control across its full stroke range. This characteristic is ideal for modulating temperature control in air handling units, fan coil units, heat exchangers, and other hydronic terminal equipment.
