VG7842RT+823C00

The Johnson Controls VG7842RT+823C00 globe valve is designed for precise fluid control in various applications. Its noteworthy flow coefficient of 28.9 Cv allows efficient flow management in systems requiring stringent regulation. This valve weighs 19 lbs, making it manageable for installation and maintenance.

It features a 1-1/2 inch NPT threaded connection, which contributes to its adaptability in several piping configurations. The actuator utilized is an MP82 series pneumatic actuator with a diaphragm area measuring 25 square inches. This design incorporates a spring-return mechanism, enabling the valve to return to the closed position without the need for constant power, enhancing operational efficiency. The actuator has a spring range specified between 3 to 7 psig, providing versatility for various application requirements.

The valve is built with a cast bronze body, which ensures durability in demanding environments. Additionally, it is fitted with brass trim to prevent corrosion and extend its operational life. The VG7842RT+823C00 can withstand a closeoff pressure of up to 109 psig, making it suitable for many high-pressure conditions. Moreover, it has a maximum supply air pressure of 25 psig (172 kPa).

This valve operates effectively across a fluid temperature range from 2°C up to 140°C, allowing for use in diverse fluid applications. It also has a maximum steam pressure capability of 38 psig for saturated steam applications. The rangeability of the valve exceeds 100:1, facilitating precise control over flow rates. To ensure reliability and performance, the leakage class is rated at just 0.01% of maximum flow, underscoring its effectiveness in preventing unwanted flow losses.
