Johnson Controls presents the VG2231VN 2-way globe valve, a robust component designed for effective fluid and steam regulation. The valve is rated according to ASME B16.1, Class 125, ensuring compliance with industry standards.
With a size of 4 inches, this valve utilizes a stem type that features a 1/2 inch threaded construction, identifiable as an "N" stem suitable for valves measuring 3 to 6 inches. Its operating temperatures range from 2°C to 138°C, making it versatile for various applications.
Pressure limits for water applications reach up to 175 psig at 66°C and 125 psig at 138°C. For steam, it can handle a maximum of 35 psig (241 kPa) of saturated steam at 138°C. The valve's flow characteristic is modified linear, allowing controlled fluid movement.
Constructed from sturdy cast iron, the body of the valve ensures durability. Its stem, made of 316 stainless steel, resists corrosion while the plug is crafted from brass for reliable sealing. This valve utilizes EPT (Ethylene Propylene Terpolymer) ring packs for effective packing.
The trim of the valve is also made from brass, contributing to its overall resistance properties. End connections are designed as flat-faced ANSI Class 125 flanges, simplifying installation and providing compatibility with various piping systems.
