The VG2431UM+845E01 valve is engineered as a 2-way, pneumatically-actuated globe control valve, designed for precision flow control in various applications. Weighing 92.0 lbs, it is built with a 3-inch valve size and features end connections that adhere to flat-faced flanged ANSI Class 125 specifications. The valve operates on a push-down-to-open basis, allowing it to control fluid flow efficiently.

The construction of this valve includes a housing made from die-formed carbon steel, finished with a corrosion-resistant layer. The internal trim is composed of brass, optimizing the valve's performance across various flow rates due to its modified linear flow characteristics. A valve stroke of 1-1/8 in. (29 mm) is provided for effective operation.

The actuator of the VG2431UM+845E01 has a spring range of 9 to 13 psig, translating to 62 to 90 kPa, and it connects via a barbed fitting designed for 1/4-inch O.D. polytubing. The diaphragm is made from EPDM, ensuring durability in demanding conditions. It can handle fluid temperatures as low as 2°C up to a maximum of 138°C. For actuator operation, temperatures can range from -29°C to 66°C, while storage temperatures are between -40°C and 80°C. With a closeoff pressure rating of 52 psig (358 kPa), the valve is capable of providing robust and reliable performance in a variety of situations.
