The VG7243LT+821C01 is a compact and functional control valve within Johnson Controls' VG7000 Series. With a size of 3/4 inches, this 2-way globe valve is designed to handle various fluid dynamics efficiently. It exhibits a solid weight of 14 lbs, ensuring stability in operation.
The body of the valve is composed of robust cast bronze, while stainless steel trim enhances its durability. This configuration is suited for applications with a fluid operating temperature range of 2°C to 170°C. The end connections are made with threaded (NPT) fittings, facilitating easy integration into piping systems.
In terms of performance, the VG7243LT+821C01 features an equal percentage flow characteristic, which promotes precise control across its operation range. Additionally, it possesses a high rangeability above 100:1, allowing for effective adjustments over a wide range of flow rates.
The leakage is rated at an impressive 0.05% of the maximum flow, which can be attributed to the stainless steel trim longevity. The actuator employed in this model is the MP82, incorporating a diaphragm area of 25 square inches for enhanced responsiveness and control capability. When it comes to pressure management, the valve can sustain a closeoff pressure of 308 PSI, thus ensuring reliability even under significant load conditions. The actuator housing is painted black while the valve body retains its bronze finish, making for a well-structured appearance suitable for many environments.
