The VG7441RT+3008D is engineered by Johnson Controls as part of its VG7000 Series of control valves. This bronze valve features a robust construction using cast bronze material. Weighing 12.1 lbs, this valve is designed for precision fluid control in various applications. With a size measuring 1-1/2 inches, this unit supports easy integration into existing systems.
The valve body functions as a two-way device that operates normally closed, requiring a push-down mechanism to open. It offers threaded NPT end connections for secure attachment to piping systems. In terms of flow control, the VG7441RT+3008D is equipped with brass trim, allowing for an equal percentage flow characteristic which aids in optimization across varying flow rates.
This model has a Cv value of 28.9 and a Kv value of 25.0, which indicates its capability to manage flow effectively. The valve operates efficiently at a fluid temperature range from 2 to 140°C for water, and also accommodates saturated steam at 38 psig. The valve's operating temperature ranges from 2 to 65°C, making it versatile for different applications. Its actuator, specifically the V-3000-8012 pneumatic actuator, is exposed and operates within a spring range of 4 to 8 psig.
The valve also boasts an exceptional rangeability of greater than 100:1, facilitating precise control over fluid dynamics. The maximum closeoff pressure for this model is rated at 9 psig (62 kPa), ensuring reliable operation under various pressure conditions.
