The VG2231UL+823C00 from Johnson Controls is part of the VG2000 Series, designed as a robust cast iron 2-way flanged globe valve. With a weight of 64 lbs, this valve is constructed to endure demanding conditions. It operates under a normally open configuration and utilizes a push-down-to-close mechanism, facilitating quick and reliable closure.

This model connects through flat-faced flanged ANSI Class 125, ensuring compatibility with a variety of piping systems. The valve size is 3 inches, which balances flow capacity and control precision. The flow coefficient is rated at Cv 59/Kv 50.6, promoting efficient fluid management. An integral feature of this valve is its brass trim combined with modified linear flow, which optimizes performance.

The valve incorporates a 3/8-inch threaded stem suitable for various actuators and exercises a stroke of 3/4-inch (19 mm). Spring range settings from 3 to 7 psig (21 to 48 kPa) allow for adjustment to meet specific application requirements, while the maximum closeoff pressure is rated at 37 psig (255 kPa).

Capable of handling an operating temperature range for valve fluid from 2°C to 138°C, the VG2231UL+823C00 is built to suit diverse operational scenarios. The valve body is rated according to ASME B16.1 Class 125 standards. Additionally, it utilizes EPT (Ethylene Propylene Terpolymer) ring packs for packing material, providing reliable sealing and leakage performance with a rate of only 0.1% of the maximum flow.
