The VG12A5KS part of Johnson Controls' VG1000 Series is engineered as a flanged ball valve suitable for various applications. With a size of 2-1/2 inches, its body is crafted from brass, while ductile iron flanges ensure durability at connection points. This two-way valve is compatible with ASME Class 150 flange connections.
In terms of fluid dynamics, the valve supports an equal percentage flow design and has a control port Cv rating of 47, making it efficient for fluid management. It can withstand a maximum closeoff pressure of 100 psig (689 kPa) and has a maximum recommended pressure drop of 30 psi (207 kPa).
The VG12A5KS is designed to operate effectively within a fluid temperature range of -18 °C to 140 °C. Depending on the actuator, it supports ambient temperatures as low as -40 °C (M9220 Spring Return) or -20 °C (VA9320 Non-Spring Return) and can function in environments as warm as 55 °C (for M9220) or 50 °C (for VA9320).
Furthermore, this model possesses low leakage, rated at just 0.01% of the maximum flow, enhancing its reliability in precise control applications. Its rangeability is rated at greater than 500:1, allowing for extensive operational flexibility and adaptability in various system demands.
