VK4-7223-303-4-10

The VK4-7223-303-4-10 globe control valve, part of Schneider Electric's VB Series, is engineered for effective flow regulation. It features a 2-way configuration that is normally closed, utilizing a stem-up-closed mechanism for efficient operation. The valve is designed with a 1-1/2-inch size and is compatible with NPT and union sweat fittings, making it suitable for various installations.

Incorporating the MK-4621 pneumatic actuator, this valve includes an AK-42309-500 positive positioner, enhancing responsiveness and accuracy in flow control. A key performance metric of the valve is its flow coefficient, rated at 28 Cv, which demonstrates its capability to manage fluid flow effectively. The actuator operates with a specified spring range of 10 to 13 psi, allowing for reliable actuation.

Constructed from durable materials, the valve body and seat are crafted from bronze, ensuring longevity in demanding environments. The stem is made of stainless steel, and the plug is brass, which contributes to the reliability of the assembly. The packing material consists of a spring-loaded TFE/EPDM, designed to prevent leaks and facilitate maintenance.

This valve adheres to ANSI Class 250 for static pressure, allowing it to withstand significant operational pressures, with a maximum allowable differential water pressure of 35 psi (241 kPa). The media temperature range accommodates fluids between -7°C and 138°C, while the actuator can handle ambient temperatures up to 60°C. Overall, the VK4-7223-303-4-10 provides a robust solution for various control applications, ensuring precision and durability in operation.
