VK4-8213-602-5-13

The VK4-8213-602-5-13, a key component of Schneider Electric’s VB Series, is constructed as a 2-way globe valve assembly. It incorporates a robust cast iron body, ensuring durability for various industrial applications. With a valve size of 3 inches, it allows for significant fluid flow regulation capable of achieving a Cv rating of 85, equating to Kvs of 74.

Designed for a normally open operation, the valve utilizes a stem-up-open action, facilitating easy access for flow through the valve. It employs a pneumatic proportional actuator with a spring return mechanism, which ensures precise control based on the system's demands. The actuator features a control spring range between 5 and 10 psig, enhancing flexibility in its operation.

The diaphragm has an effective area of 50 square inches and allows for movements of 1 inch during stroke operations, which is crucial for fine-tuning operations in various systems. Air connections are made through a 1/8 inch NPT connection.

Additionally, this assembly is accompanied by a positioner, improving its response characteristics under varying flow conditions. Its NEMA Type 1 enclosure rating makes it suitable for use in environments where additional protection against dust and moisture is necessary. This valve operates effectively across a wide temperature spectrum, from -29°C to 104°C, ensuring reliability even in demanding conditions.
