The VG2231UL+823D00 from Johnson Controls is a cast iron 2-way flanged globe valve, known for its reliability in fluid management systems. Weighing 64 lbs, this valve is structured in a normally open configuration, utilizing a push-down-to-close mechanism for operation. Designed with efficiency in mind, it has flat-faced flanged ANSI Class 125 end connections, providing secure installation and adaptability to different systems.
Measuring 3 inches in size, this valve is engineered to handle modified linear flow, with brass trim contributing to its durability. The flow coefficient is rated at Cv 59 and Kv 50.6, facilitating effective flow regulation. The actuator stroke is 3/4 inch (19 mm), allowing for precise operation. The 3/8-inch threaded stem type (L Stem) promotes reliable functionality during operation.
For pressure handling, the valve features a spring range of 4 to 8 psig (28 to 55 kPa) with a maximum closeoff pressure of 34 psig (234 kPa), ensuring safe performance across varying conditions. The valve is suitable for fluid temperatures from 2°C to 138°C, aligning with the standards set by ASME B16.1, Class 125. Additionally, the packing material is comprised of EPT (Ethylene Propylene Terpolymer) ring packs, which help maintain its integrity and leak performance with a leakage rate of just 0.1% of the maximum flow.
