VK4-7223-303-4-5

The Schneider Electric VK4-7223-303-4-5 globe control valve is designed with a robust construction, featuring a bronze body and seat for reliability in fluid control applications. This valve is classified as a 2-way design with a normally-closed configuration, maintaining its closed position until acted upon by the actuator. The stem-up-closed feature ensures secure closure. This valve incorporates a pneumatic actuator, specifically the MK-4621, which provides necessary drive force, while the included AK-42309-500 positive positioner maintains the desired flow rates and accuracy.

With a size of 3/4 inches (or 20 mm), the valve is suitable for various installation options, including NPT and union sweat connections. The flow coefficient (Cv) of 5.5 allows for significant flow control, while the actuator spring operates within a pressure range of 10 to 13 psi. The valve is engineered to handle static pressure ratings of ANSI Class 250, ensuring it can withstand high-pressure applications. Additionally, the maximum allowable differential water pressure reaches up to 35 psi (241 kPa), making it an optimal choice for different operating conditions.

The VK4-7223-303-4-5 is designed for media temperatures ranging between -7 to 138°C, allowing it to function effectively across various temperature scenarios. Furthermore, the actuator can operate in ambient temperatures up to 60°C without compromising performance. The valve's stem is made from stainless steel, enhancing its durability, while brass is used for the plug material. Packaged with spring-loaded TFE/EPDM packing, this valve ensures reliable sealing and performance in demanding environments.
