The VG2431TM+843E00 from Johnson Controls represents a robust option in flow regulation with its cast iron body. This particular globe valve is designed for two-way operations and features a weight of 76 lbs, providing substantial stability in installations.

Operating on a normally closed basis, users can activate the valve using a push-down-to-open (PDTO) approach. The end connections are compliant with flat-faced flanged ANSI Class 125 standards, ensuring compatibility in various setups. This valve size measures 2 1/2 inches, allowing for significant fluid movement, reinforced by a flow coefficient of Cv 47, which converts to Kv 40.3.

The valve uses a 3/8-inch threaded stem, categorized as an M stem, and can manage an actuator stroke of 3/4 inch (19 mm). The spring range spans from 9 to 13 psig (62 to 90 kPa), while the maximum closeoff pressure is rated at 75 psig (517 kPa), enabling robust functionality under pressure.

Fluid temperatures passing through the valve can vary from 2°C up to 138°C, demonstrating versatility for various applications. Additionally, it meets ASME B16.1, Class 125 ratings for body integrity.

For sealing, the packing material consists of EPT (Ethylene Propylene Terpolymer) ring packs, and the leakage rate is remarkably low, quantified at 0.1% of the maximum flow. This illustrates the VG2431TM+843E00 as a reliable choice for regulatory tasks in fluid control systems.
