The VG7443NT+423AGA model from Johnson Controls is a precision-engineered control valve made of durable bronze. This valve is tailored for a variety of applications and features a size of 1 inch (DN25). Weighing 8.0 lbs, this model is ideal for installation in a variety of systems. The design includes a two-way configuration that operates normally closed and pushes open with a simple downward action.
Integrated into this valve is the VA-4233-AGA-2 electric actuator, which utilizes a spring return mechanism and maintains the stem in an upright position. The control signal for this actuator operates on a floating (3-wire) basis to enhance its responsiveness. It functions consistently under an operational voltage of 24 VAC/VDC, compatible with standard networks.
The VG7443NT+423AGA is notably recognized for its flow efficiency, which is attributed to the stainless steel trim enabling equal percentage flow characteristics. With a flow coefficient of 11.6 (10.0 Kv), it ensures reliable flow management in demanding environments. Additionally, the maximum closeoff pressure is rated at 108 psig (744 kPa), allowing for robust performance under various conditions.
Designed for fluid operation, the valve functions effectively within an operating temperature range of 2 to 121°C for water and can also accommodate 15 psig of saturated steam. Constructed from cast bronze, this valve also features stainless steel components for the stem, plug, and seat, ensuring durability and longevity in service. The end connection type is threaded (NPT), providing straightforward integration into piping systems.
