VK4-7313-202-4-9

The Schneider Electric VK4-7313-202-4-9 represents a 3-way globe valve assembly equipped with a pneumatic actuator, enhancing control capabilities in fluid applications. The robust actuator model MK-2690 incorporates a spring-return mechanism along with a positive positioner for precise positioning. This assembly features an effective diaphragm area measuring 6 square inches (39 cm²), catering to efficient fluid dynamics.

Operating temperature capabilities range from -29°C to +104°C, allowing this valve to function effectively in various environments. Moreover, it can tolerate storage conditions within the temperature range of -40°C to +104°C. The design accommodates a humidity range of 5% to 95% relative humidity, ensuring reliability even in less favorable conditions.

Air supply pressure should nominally fall within 15-20 psig, with a maximum allowable pressure of 30 psig. The nominal spring range with actuator code 202 is estimated to be approximately 5-10 psig. The actuator achieves a nominal stroke of 1/2 inch (12.6 mm), enabling flexibility in control.

This 3-way valve exhibits a flow coefficient (Cv) rating of 20, correlating with efficient flow characteristics. The valve connects through a 1-1/4 inch NPT threaded connection, facilitating installation and integration into existing systems. The valve action allows for mixing; when the stem is positioned upwards, it directs flow from port B to port AB. Key materials include a bronze body, brass plug, and stainless steel stem, ensuring durability and resistance to wear.

Air connections are designated as 1/8 inch FNPT, adhering to standard connection practices. The valve linkage type AV-7400 contributes further to the module's operational integrity. Overall, the VK4-7313-202-4-9 valve assembly stands out as a reliable choice for various process control applications.
