VK4-7223-203-4-7

The VK4-7223-203-4-7 globe valve assembly from Schneider Electric is engineered for efficient fluid control in demanding environments. With a nominal size of 1 inch NPT, it effectively manages fluids with a flow coefficient of 10 Cv, which highlights its capability in precise fluid regulation. This device operates in a normally-closed configuration, meaning that it remains closed until signaled to open, which enhances safety in system management.

Central to its operation is the MK-2690 actuator, which integrates the AK-42309-500 positive positioner, ensuring high fidelity in flow control. The valve's operational characteristics permit a spring range from 8 to 13 psig, while its air supply pressure can range between 15 to 20 psig, making it adaptable to various applications.

Constructed from bronze for durability, the valve includes brass trim components for reliability. The valve’s effective area measures 6 square inches, allowing for substantial operational performance. Operating conditions for this assembly are well-defined: it can function in ambient temperatures up to 104 °C and withstand fluid temperatures reaching 121 °C. Connections to this valve utilize NPT air fittings, providing a secure and standard interface for installations. The VK4-7223-203-4-7 assembly is thus a viable solution for industrial processes requiring stringent control and reliability.
