The Johnson Controls VG7443ST+823D01, part of the VG7000 Series, is engineered as a 2-way control valve made from cast bronze. Weighing in at 26.0 pounds, this valve is designed to handle a range of pressures and fluid temperatures effectively. It has a size of 2 inches, ensuring a robust fit for various plumbing configurations.

Constructed with a body of cast bronze and a bonnet of brass, its durability meets demanding operational requirements. The valve's trim is made from stainless steel, providing resistance against wear and corrosion. This model operates under a maximum actuator supply pressure of 25 psig (172 kPa), ensuring reliable performance under pressure.

The spring mechanism supports a range between 4 to 8 psig or 28 to 55 kPa, enabling flexibility in its pressure settings. Additionally, it can achieve a maximum closeoff pressure of 21 psig when configured as normally closed with a supply pressure of 0 psig. Fluid operating temperatures for this valve can go from 2°C to 170°C when using a pneumatic actuator designed for saturated steam applications at 690 kPa. In typical valve operation, the temperature range is limited to between 2°C and 65°C.

For reliable sealing, the stem, plug, and seat are constructed from stainless steel, utilizing PTFE/elastomer V-rings packing. This design enhances the valve's longevity and efficiency in sealing applications. The end connections are designed for NPT (National Pipe Thread) threaded applications, facilitating straightforward installation across various systems.
