VK-7213-612-4-11

In the realm of fluid control, the Schneider Electric VK-7213-612-4-11 model stands out as a pneumatic globe control valve assembly. This piece is designed primarily for two-way operation with a stem-up-open configuration, typically remaining open unless actuated otherwise. With a valve size of 2 inches NPT, it is suitable for various applications requiring durable and efficient flow management.

The valve achieves a flow coefficient of 40 Cv, ensuring robust performance across different media. Crafted from bronze material (ASTM B584), it combines strength with resistance to corrosion. Internal components feature a brass plug and an EPDM disc, while the stem is constructed of 316 stainless steel, providing durability under pressure.

At the heart of this assembly is the MK-6611 pneumatic actuator, which offers an effective area of 50 sq. in. This actuator operates within a spring range of 5 to 10 psig and connects to the valve via the AV-430 linkage. It requires a supply air pressure of either 15 or 20 psig for operation. Notably, the valve can withstand a close-off pressure rating of up to 60 psi with a 15 psig supply and can handle pressures up to 120 psi when supplied with 20 psig.

This control valve performs within a temperature range of -7°C to 138°C for the control media, accommodating various environmental conditions. Additionally, it meets ANSI pressure class standards, rated at 250 psi. Impressively, it can handle pressures up to 400 psi at temperatures lower than 65°C, showcasing its impressive capability to adapt to demanding applications.
