VK4-7213-611-4-11

The VK4-7213-611-4-11 from Schneider Electric is a pneumatic control valve assembly that stands out in performance and design. This unit features a 2-inch NPT valve size and an impressive flow coefficient of 40 Cv, promoting efficient liquid and gas handling in diverse scenarios. Operating on a normally-open principle (stem-up-open), this valve is built from durable bronze for its body, complemented by brass trim and a stainless steel stem, ensuring longevity and resilience.

The control valve's design incorporates a spring-loaded TFE packing, enhancing its sealing capabilities and reliability during operation. The actuator is a pneumatic piston type fitted with a positive positioner (MK-6601), providing consistent control through ranges of 3-8 psig. With an effective area of 50 square inches, the actuator is capable of managing substantial flow volumes.

This valve assembly can withstand a static pressure rating of up to 250 psig, ensuring robust operation in demanding conditions, and can handle a maximum of 400 psig at temperatures below 150 degrees Fahrenheit. The media temperature range for effective operation lies between -7 to 138°C, accommodating various fluid types, including steam with a maximum inlet pressure of 35 psig. The flow characteristic is defined as equal percentage, enabling predictable flow performance across a range of conditions.
