Johnson Controls presents the VG2231TM+843C00, an effective cast iron 2-way flanged globe valve suitable for various applications. Weighing in at 57 lbs, this valve operates with a normally open principle and utilizes a push-down-to-close (PDTC) mechanism. The valve is equipped with flat-faced flanged ANSI Class 125 connections, ensuring compatibility and stability.

In terms of size, the VG2231TM+843C00 has a 2 1/2-inch diameter, making it ideal for moderate flow applications. The internal trim of brass allows for a modified linear flow, giving it a flow coefficient of Cv 45 and Kv 38.6, which facilitates smooth operation. This globe valve comes with a stem type of 3/8-inch threaded stem (M Stem) and offers an actuator stroke of 3/4-inch (19 mm) for responsive actuation.

The valve's spring range operates between 3 to 7 psig, converted to 21 to 48 kPa, making it suitable for various pressure applications. Furthermore, it can handle a maximum closeoff pressure of 109 psig (751 kPa), along with an operating temperature range for valve fluid from 2°C to 138°C.

The valve body is rated according to ASME B16.1, Class 125, ensuring robust performance standards. For sealing, EPT (Ethylene Propylene Terpolymer) ring packs are used, providing effective leakage management. This valve maintains a leakage rate of just 0.1% of the maximum flow, reflecting its efficiency and reliability in operation.
