The Johnson Controls VG12A5GS is an efficient flanged ball valve created to manage fluid flow in demanding environments. Weighing 34 lbs, its robust design incorporates 300 Series stainless steel for the ball and stem, enhancing corrosion resistance and longevity.
This valve is characterized by its operational temperature range from -18 °C to 140 °C. It also has a commendable Cv rating of 47, indicating its ability to handle substantial flow rates. With a maximum allowable closeoff pressure of 100 psi (689 kPa), the VG12A5GS can withstand significant pressure while maintaining operational integrity.
Designed with a size of 2-1/2 inches (DN65), the valve offers large face-to-face dimensions, making it easier to integrate into existing piping systems. The end connections comply with ASME Class 150 flanges, ensuring compatibility with standard industrial fittings. Fluid flow characteristics are defined as equal percentage, supported by a rangeability of greater than 500:1, which allows for precise control across varying flow conditions.
Leakage rates with this valve are impressively low, quantified at just 0.01% of maximum flow, which is critical in applications requiring high reliability. The valve body, constructed of brass and fitted with ductile iron flanges, provides a pressure rating of up to 250 psi at temperatures from -20 to 38 °C, and 218 psi at 140 °C. The seat is made from a graphite-reinforced PTFE material, backed by an EPDM O-ring, to ensure a robust seal. For actuation, this valve is compatible with M9124 or M9220 actuators, facilitating operational efficiency in various control scenarios.
