The VG7243GT+72CHGC from Johnson Controls functions as a robust two-way control valve, designed to excel in industrial applications. Weighing in at 4.8 lbs, it has a compact size of 1/2 inches, allowing ease of installation in confined spaces. Constructed from durable cast bronze, the valve body stands up to rigorous use, while the internal trim is made of stainless steel for enhanced longevity. This model employs an electric spring return actuator (VA7820-HGC-2) that requires a control signal of 24 VAC.
A noteworthy characteristic of this valve is its ability to manage a broad operating fluid temperature range from 2°C to 170°C, ensuring reliable performance across diverse conditions. The maximum closeoff pressure of 283 psig enables it to withstand significant pressure without compromising functionality. Additionally, the VG7243GT+72CHGC provides a flow coefficient (Cv) of 4.6, contributing to its effective flow characteristics.
Moreover, the valve features a proportional control signal within the 0-10 VDC range, offering precise adjustment capabilities for controlled environments. Feedback from the valve operation is also included, alongside two auxiliary switches, enhancing its functionality. With a rangeability greater than 100:1, this valve ensures fine-tuned performance, making it suitable for applications demanding high precision and reliability.
