VG2831VM+845C01

The VG2831VM+845C01 from Johnson Controls is a 3-way mixing flanged globe valve designed to facilitate effective flow control in various systems. This particular model has a substantial weight of 151 lbs and is crafted in a 4-inch size, making it suitable for significant applications in industrial settings.

The valve features a 3/8-inch threaded stem, commonly referred to as the 'M' stem, for secure connectivity, paired with a factory-mounted MP84 actuator that boasts a diaphragm with an effective area of 50 square inches. The actuator efficiently manages pneumatic control signals through its spring-return mechanism, which operates within a spring range of 3 to 7 psig.

The valve boasts a stroke length of 1 1/8 inches, ensuring responsiveness to control commands. Closeoff pressures are rated at 25 psig for normally open (N.O.) ports and 6 psig for normally closed (N.C.) ports. The actuator is designed to handle a maximum supply pressure of 25 psig (172 kPa) for pneumatic systems.

End connections utilize Class 125 ANSI flat-faced flanged connections, facilitating integration with existing piping configurations. A robust body constructed from cast iron and finished with black lacquer ensures durability in demanding environments. For enhanced longevity against corrosion, the stem is made of 316 stainless steel, reinforcing reliability in challenging conditions.
