The VG18A5GT is a high-performance three-way ball valve from the VG1000 Series by Johnson Controls. This valve is ideal for applications requiring robust and accurate fluid regulation. Weighing 43 lbs, the valve is constructed with a body made of brass, complemented by ductile iron flanges for added strength.
This unit features 300 series stainless steel for the ball and stem, delivering lasting durability and resistance to corrosion. With a valve size of 2-1/2 inches (DN65) and large face-to-face dimensions, this valve integrates easily into existing systems via ASME Class 150 flange connections.
Fluid operating temperatures for the VG18A5GT range from -18 to 140 °C, making it suitable for various industrial processes. The valve's Cv ratings indicate a flow capacity of 74 Cv for the control port and 47 Cv for the bypass port. It is engineered with both equal percentage and linear flow characteristics, allowing for precise control and flexibility.
The valve's pressure ratings are robust, supporting 250 psi at temperatures between -20 and 38 °C and 218 psi at 140 °C. Additionally, it features exceptional rangeability of greater than 500:1, which enhances flow control capabilities across multiple operating conditions. For sealing efficiency, the valve is equipped with a graphite-reinforced PTFE seat backed by EPDM O-rings, ensuring minimal leakage. The VG18A5GT is compatible with actuators such as the M9124 and M9220, making it a versatile choice for fluid control applications.
